Coffee nerds don’t like pressurized baskets because it takes the fun out of dialing in a shot and does the work for them, making a really nice shot without their expertise. Can’t change my mind. Also feel this way about moka pots. Not necessary to pour hot water into the bottom chamber first (cough Hoffman cough). The moka pot has a perfect design already and is dead simple, not much experience needed.
@@homedepotindustrialfan936 I agree with the pressurized baskets. They make good coffee. However, they are also boring and it's way more fun to have horrible shots sometimes and exceptional shots other times
@@homedepotindustrialfan936lol have u guys ever tried to 1) do latte art with espresso pulled on pressurised porta filter and 2)make decent light roast coffee espresso
I feel like they are the same people. Those who tend to get deep into hobbies like espresso or hifi will most likely get into the other as well. At this point it must be a personality trait "how deep into *insert run of the mill object" can I go?" Audiophiles are usually into coffee, and napolean pizza, and beer, and wine, and so on...
Lance, I love you. You have a hypothesis, and then you experiment and present data. Thank you for inquisitive nature and not trying to hype the latest thing.
I don't know, there are dozens of cases of researchers presenting evidence that seems to support their long-held belief which turns out not to replicate when a neutral researcher repeats the experiment. Especially in an area with as many variables as espresso, we should be pretty careful of confirmation bias. Still, if the results are as obvious as shown here, they should be easy for others to replicate!
I always had a feeling breville may have known something making their entry stuff 54mm. Makes sense for a beginner machine to be easier to dial in and more forgiving on the grind with the cheap grinders of the all-in-one machines. Same with full automatics, they always use smaller pucks than 58mm, might have different reasons there with space and costs but still.
Lol it’s not really about size of the basket but the potential in puck dept, the Caravel is just small in every regard. There small diameter basket out there that allows the high columns of coffee but it’s not true on all small diameter machines as some of them just make very small shots.
Yep it is small. The aspect ratio is definitely more analogue TV than widescreen but a deeper basket would be v.cool. I'm used to my 12.5gm in 31gm out. It means I get to drink more coffees per day.
I have a cheap 51mm Delonghi ECP3420 set up at my vacation pad with a Timemore hand grinder and a bottomless portafilter and I’ve noticed a richer mouthfeel and almost chocolate like consistency in the espresso I make on this set up. So… your experience here adds up to my experience! Thanks for all you do. You are really pushing the frontiers of espresso my man!
Aspect ratio is almost certainly the wrong metric. Depth of puck is almost certainly the only thing that matters, and the aspect ratio is just a derived value that comes from nothing other than the dose. Working with a deep 58mm basket is still only going to be a matter of depth. I would feel 100% certain that if you pulled a shot in the 49mm and 58mm with the same depth, but ran the shots so that they had a volume of fluid proportional to the volume of coffee in the baskets, the shots would be near identical. There is something important here, and you have been iterating towards it for a while now. This is good stuff. I suspect that what is needed is a parametrisable model of extractives flow for a coffee particle, and basic 3D model of flow though the puck coupled to extractives flow. You have a range of polar and non-polar extractives. The rate of extraction of polar extractives will depend upon the concentration already in the water flowing past. Non polar extractives may extract differently with changes in pH and other interesting things. In principle it should be possible to predict the extraction profile if you have such a model. All the messing about with grind size, grind distribution, and pressure is just a very decoupled and inexact way of trying to optimise the the balance of extractives. But it is horridly unstable, and there is no sensible overarching model to guide us. These videos point the way in a useful manner.
++ having worked as a barista and serviced a variety of commercial machines, my experience is that the bed depth is what matters. This is likely also the reason that shots extracted using a "single" basket are never as good as with a "double" basket on the same machine with the same coffee, grind notwithstanding.
I‘m with you on this. So Coffee bed height and water flow per surface area has to be constant to achieve similar results. So in theory if you 2 shots on the decent with same flow / area ratio and puck height they should be quite similar…
Yep I agree with you here 100%. Depth is the important metric being tested here, not aspect ratio. Should be easy to test as well with the same setup in this video. The dose ratio would be 58^2 / 49^2 = 1.401. That does mean you'd need some pretty beefy 58mm shots, 28g of coffee compared to 20!
Selling all my 58mm machines and moving back to the Flair PRO 2. Lol. Great video, super interesting results! Did you by any chance compare with a declining pressure profile? We know that those shots tend to taste better so I'd be curious to know if the cups converge in terms of taste when you go a little easier on the shallower puck.
Glad to hear this as I have a Flair Espresso, which has a narrow, deep, bed. To keep it brief, I've always liked the shots I've pulled with it but now I'm not going to feel the FOMO of the Flair 58. Thank you!
Ok, so this hansome man, just proves that all tha baristas said you need professional coffee machine for more pressure, you have to have 58 mm basket for better taste were wrong. This exactly man, Lance Hedrick, eventually prooved, that awesome cup of espresso can be done with home machine like Dedica 685 or similar, that gives you 7 bar pressure, have more narrow basket, which is 51 for delonghi! And you also don't need Niche Zero anymore because of Turin DF 40 and DF 54. Love you man, thank you som much!
I think the 58mm is also the most popular because you have the most available accessory options for it. Lots of baskets, tampers, funnels, so that makes it more convenient.
Lol, just made a similar comment before seeing yours. Seems there's a cycle going on. More accessories, parts and upgrades are available because it's so popular commercially and their availability makes the size more attractive which keeps it popular.
I tried doing 20g in my 58mm portafilter instead of my usual 18g with the idea that I would have to go coarser to maintain the the same extraction time. Best cup I've made in a long time. Thank you for the thoughts and helping me better understand what's going on.
I have the step down and got the dosing funnel made for it. It makes the workflow better as you don’t have to clean the sides. I also got a bunch of puck screens to fill the head space. Overall I’m happy with the results.
Thank you for making this video. I have not purchased my espresso machine yet and this kind of content makes me feel better about buying a smaller portafilter machines. I've been mentally giving negative 'points' to any machine without a 58mm when trying to decide what to buy. I might still get a 58mm machine, but this kind of content helps me make a more informed decision when purchasing. And yes, please lets have the follow-up video!
This is amazing and fascinating information. Maybe I can stop having 58mm envy! My kit is all Breville (Barista Express for years, with the recent addition of a Bambino), and I generally really enjoy them. I've never worried much about the grinder on the Barista Express, because I've always known my technique is the limiting factor. I'm just not that much of an expert. But in the back of my mind, I've always had this nagging worry that the 54mm baskets were leaving something on the table. Not "professional" enough. Somehow the "lesser" option. I think I'm done with that. I will continue to rock my 54mm baskets without that inferiority complex. Thank you for all of your work, Lance. I've also switched to your "coarser grind, fuller basket" workflow, and it's significantly improved the consistency of the shots I pull with the Barista Express grinder. No joke, that video was like a $100 grinder upgrade for me.
I too had puck envy using my 54mm Breville Basista Express portafilter thinking someday that I would upgrade to a a more "professional" 58mm portafilter espresso machine. This video finally answered my curiosity whether or not 58mm filters are indeed better. Looks like my Breville will be sticking around for a long time. BTW, I upgraded to an IMS Precision 18-22g filter basket a long time ago since I wanted a fuller espresso shot with 20g to 22g of coffee (vs only 18g with stock dual shot filter basket).
This is actually very similar to a philosophy that you use in Brewing of high-end tea. Use more leaf less water and a short contact time. Have whole Leaf not ground or broken leaves. And a lot of them use a smaller amount of water and have a contact time of less than 30 seconds. This will give you a rich and vibrant Brew extracting the delicious parts of the leaf without digging too far into the bitter and tannic unpleasant flavors that live at the end of Brewing when seeking every ounce of extraction. Now this is easy to say for tea because Tea Leaves Can much more easily be rebrewed to make up for the Lost cost that using so much product creates. And for most people the cost of that extra gram or two of coffee can be tough to stomach.
I would say it is definitely because of 1. Coarser grind size leads to less channelling over time. The dense fine ground puck will certainly have many channels forming everywhere. 2. Larger depth in puck gives more time for the various higher and lower pressure zones coming from the group head to even out. 3. It probably also creates a lower disparity between the over extracted centre of the puck, and the under extracted edges. (as demonstrated in the experiments with the cooker cutter you previously mentioned). It would be interesting to repeat the cooker cutter experiment with various ratios and depths of puck.
Great video. As someone who’s recently swapped from a lifetime of 58mm machines to a La San Marco group lever - I’m totally with you. Would love to see more lever content from you too, as a side point.
This reminds me a lot of the discussions (pre pandemic) of the Flair Pro / Pro 2 vs the Robot basket. Somehow it was to be believed that Robot’s bigger basket yield a more professional shot than Flair’s 45.5 due to its size but it was never my experience 😅 I also preferred shots made by these antique Italian lever machines. Thing is, with the smaller Flair Pro size (which I still use, the first one with the new basket) it was really, really difficult to make a bad shot. It’s also very much true that you could grind quite a bit coarser than on the robot. The texture was always quite good, even with coarser grounds, and channeling still happened but 90% of the time it was due to weak tamping. Even Flair has moved to 58 now so don’t really know how reversible this trend is or if it’s worth it, but loved the video and what you brought to the table!
Fuji are growing faster than anyone right now and Sony’s ZV line and Canon’s crop stuff helps their sales. It’s really only numbskulls (like me!) and pros that understand why a larger sensor might be better for their work that use them.
What a rabbit hole you have just opened for me 😅. I dialled in my Solis/Breville (54mm) as follows: 18gr in, 36gr out -> adjust grind size to taste/ pressure/ speed. I was only a click away from minimum on the grinder… Started thinking about better grinders, new machine,…. Now I just tried 24gr/ 52gr with a much coarser grind….. and it completely changed the espresso. What a difference ❤. Instead of buying new gear, I’m just going to use more beans from now on 😅 & much more experimenting the coming days 😊 Thanks for another great video. PS: If I were to consider a new machine, it would have to be one that is ready to use in a few minutes… so please keep the reviews of thermoblock machines coming ❤
Cant honestly believe how great of a content you are creating right here. Thank you very much and keep up the good work. I do not tend to fomo after a new machine, but it is so interesting to dig deeper into the world of espresso making through the lens of an coffee expert like yourself. Hope im nit being too needy/positive or something, but i wanted to give you a positive feedback for a long time.
I’m using a 53mm La Spaziale, the puck integrity is better but can’t say it tastes any better than a 58mm. The quality of coffee is still the most important thing.
Finally the biggest contemporary debate! Although you mentioned the comparison in some of your previous reviews, BuT this video def needed. Thank you Lance for bringing up the topic!
Thanks for the video! Some pointers/thoughts: - I think John from Decent says larger headspace leads to more body/texture, which also aligns with my experience so far. - A thicker puck should be much more forgiving regarding inconsitencies (grinder, puck prec, pump, shower head) - 58 mm pucks are much more prone to mistakes in prepariation and espresso extraction is pure chaos - A thicker puck should lead to an increased extraction gradient from top to bottom, as water accumulates solubles throughout its flow through the puck. I would imagine in extreme cases you promote overextraction of the top and underextraction of the bottom (obviously, this is always the case during espresso extraction to some extent) - I still think extraction yield is merely a macroscopic quantity, that does not provide information on what is actually happening inside the puck. It mainly provides a measure of consistency. - For me 58mm is mainly interesting as an ecosystem (baskets, portafilters etc) - How about a basket that resticts flow, while maintaining even extraction (anti high flow basket)? This would allow for a coarser grind and maybe lead to the same results? Keep up the good work!
if John says that, I heartily disagree. I believe i've discussed the science of it in a video, but it is pretty well known, hence the spacer kit Sworks sells and the lessening of the headspace John has been doing on the decent. i'd be curious to see where he said that. I have not heard this from him
As a photographer, I care deeply about Aspect Ratio. Give is 65:24 in-camera for more camera bodies, folks! Fuji *manufactured* the XPan/TX1, the legacy is there, they should put it in their X-Mount bodies. I also vibe hard with manufacturers having a hard time selling narrower baskets because there's some market perception that 58mm is the best. Folks just figure the bigger number is better, but there are also often a lot of ways where it's not relevant.
@@Spoobie123 That 55 seems like a sweet lens. Part of what seems really sweet about the GFX line is that even if you crop to FF area, you still have around 60mp or more. With the 55 you get a wide normal to a tight normal with no loss of resolution compared to something like a Canon R5. Plus, native 65:24. :)
Very interesting, thank you for constantly searching, trying and brainstorming ideas, challenging curent standarts and putting them to the test. One fella mentioned that flair pro 2 has tottally different taste from flair 58 because of the filter size, and your video ties it up nicely.
Thank you Lance for calling out, questioning and investigating things we take for granted. I’m a beginner looking into an espresso machine and I was wondering about this as well when I was looking into portafilter size. I thought this it would be better if the water whatever route it chooses had more coffee grounds to travel than a broader area with less travel.
I have literally always wondered about this. But like Lance said at the start. Unless it is on the same machine. There was always waaaay to much variables. I do a standard of 18g per puck.
Banger after banger. Coincidentally, I'm currently using a 51mm machine, but I also own a 58mm machine, both at different locations and paired with a different grinder. I always found the shots from the 51mm machine to be more pleasant, with less astringency. I would've bet it was because of the different grinder, but now I am unsure. I plan to make a fair (enough) comparison one day to find out for myself.
as a flair signature owner i am very excited for this. experimenting with dosing on that portafilter can be weird, i usually stay in the 15.75-16.5g range though but i've been having a sneaking suspicion I could be going higher. excited to see your findings!
Darcy’s law applied to espresso: total shot mass = some constants*5% smaller particles size^2*basket diameter^2*pump pressure/coffee depth*shot time. Can’t wait to see the next experiment!
I ran out of coffee during a bad ice storm in February, resorted to re-grinding some of my GF's Folgers Classic (from Costco). The results were surprisingly tasty, there was some nice crema.
@@missinglink_eth It worked better than I expected, especially with the pressurized basket. Lance is known to be a big fan of pressurized baskets (not):):):):)
It's much easier to remove a used puck from a 58mm portafilter than from smaller ones, which could explain why commercial establishments and machines opt for this size. Also, the tamp is more consistent with a shallower portafilter - you might have to go double with a deeper one.
You may be onto something. Speed of puck removal and having a clean basket ready for a reload is an important consideration in a commercial establishment -- as well as speed of preparation in many home use applications. The unaddressed factor: #Drinks/hour.
@@LanceHedrick Well, it's certainly true in my experience. A thin puck is always easier to dispose of than a thick one. Less tension holding it in the basket.
Im a home roaster and let me tell you... temperature greatly affects the way my roasts come out. Winter sucks for roasting and hot summer nights is almost as wild. I too try to roast when i have a consistent temp. 20c to 25c has served me well but sometimes that may be very early in the morning.
It's an interesting proposition basket depth vs width. I don't imagine there was much science involved in the selection of the basket diameter going back to the early days of espresso, it would have been a process of trial and error and settling on 58mm because it just worked. Keep digging Lance, there's some very intriguing results in these experimental espresso videos and we're all here of the ride 😎
It was quite interesting listening to your analysis of this phenomena. As a brewer of beer we have a similar tendency to opt for tall skinny mash tuns to create a column of grain, often adding rice hulls to create a "coarser" mash to prevent channeling and, in essence, better extraction. I'd love to bring pressure into our world, as everything is done via gravity, it could be really interesting!
You have just confirmed in a quite a bit more scientific way, my observations going from 51mm to 58mm. Even though I went from a pretty shitty machine like the Dedica to the Bianca, as long as I stick with medium dark roasted coffees (I imagine mostly because the lack of temperature control or any stability to speak of on the Dedica really affect lighter roasted coffee), I'm able to consistently pull good shots and the Sage Smart Grinder Pro is able to do a very decent job at grinding the beans for the required outcome. Slight variations in my workflow barely affect the end result. Several days into owning the Bianca with the 58mm portafilter, I discovered that the Sage was really running out of steam when trying to grind lighter roasts to the much finer level required for the shallower 58mm puck to deliver the necessary resistance. I went and bought a DF64V that's doing an awesome job but I've discovered that every little difference in the way I'm prepping the puck or pulling the shot can make or break the end result. P.S. I do not yet have puck screens for the 58mm portafilter and I was using a relatively thick mesh one with the Dedica.
I started my espresso journey with a BBE about 8 years ago and always felt I got my best espresso shots with it despite slowly climbing my way to 58mm machines - more recently a GCP, then an ECM Classika. Then 2 months ago we snatched up a Bambino Plus for coffee during an extended stay at a distant friend’s. And wouldn’t you know it? I was pulling really tasty espresso again. I thought maybe I was romanticizing the quality of the BBE espresso but your video, Lance, shows that maybe my mind wasn’t playing tricks on me after all. Apparently aspect ratio matters! Thanks for the video!!
I’ve still got my old La Pavoni Pro, despite upgrading (through various steps) to a LM Leva X, and I’ve often wondered about this. So much more surface area for channeling to occur in the 58mm!
Its true that with more width, there is more surface area, but the puck is therefore also thinner with same amount of coffee - to me it seems then less likely that a channel might appear, compared to a much deeper puck where differences in the puck prep quickly add up to more easily allow high/low pressure zones. Shallow puck means less variance across the surface imo... so a bit less finicky, less prone to prepping errors in my experience
If you want to test the effects that different puck thicknesses have on how shots taste you could also consider using a Cafelat Robot where the basket can basically hold as much coffee as you might want and you don't have problems with headspace since you pour water directly on top of the coffee. Then you can play around with smaller doses with finely ground coffee (thin puck) and bigger doses with coarser grounds (thick puck), trying to find different doses and grind size combinations that give you similar flow rate and shot times for the same shot ratios. Obviously with a manual machine like the Robot the biggest challenge will be to keep the pressure profile and the other variables as consistent as possible from shot to shot.
Really enjoyed this, great investigation! I think there are 2 parts to it, which you mention but smushed together a bit: 1) It appears that puck depth is key to being able to grind coarser; 2) With a deep puck, it is more economical to have a narrow basket so you don't have to use a lot of coffee to get the effect. If this is right, then you should get similar results with the same puck depth, regardless of basket diameter or aspect ratio. Looking forward to tests of this! The 58mm EPNW triple basket (and similar baskets) were favorites of mine for many years. I'm currently using IMS 29mm deep basket on my Cremina for same reasons.
Love the video and I love that you are pushing to re-examine "best practices" that may just turn out to be Dogma. I suspect you will be better served in your goals of inviting other people to try this experiment, making a scientific approach to coffee more common, and to not cause FOMO/upgrade-itis by minimizing the comments about which trial tasted "better" and focusing on highlighting which trial had more/less floral, sweetness, acidity, astringency, bitterness, viscosity, evenness/efficiency of extraction, etc. (sorry for the run-on sentence 😃) I think when you invoke the word "better" you instantly spark the thought chain of, "well if that makes better coffee then I want to buy that!" You also run the risk of alienating people by challenging their idea of what "better" coffee is or sounding condescending, which I know is something you are specifically working on in your presentation style. For what it's worth, I rarely if ever thought you sounded condescending and this video will certainly be in the back of my mind if I ever buy an espresso machine. Cheers❤
this further suggests that going finer bears diminished returns. after a certain point the porosity of the bean itself allows for maximum potential extraction, there is no need to break it down further, and instead we should focus on is optimized water flow through the puck, i.e. by creating deeper baskets that concentrate the water flow, as opposed to shallow wide baskets that will have "macro channels".
Great video. Another reason to go with the Strietman. 49 mm basket to boot. As a relative newbie it allowed me to experiment and make great espresso . I learn each time I use it.
So funny that I had this thought recently. As I used a Breville 870XL for years, and upgraded to a Lelit Bianca. And noticed the difference in how much more punishing it was on the 58mm and how much more fine I had to grind. About 4-5 steps on my Kopi Concept grinder for the exact beans for years.
The engineer in me loves what your doing Lance, another few of these vids are you'll be talkin' at full on Irish speeds . Crackin' stuff Daddy Hoff must be proud.
Thank you so much for this! I have a really cheap 51mm 28g portafilter because I like big espressos, and I was grinding super coarse to keep extraction at 30s and the shots every time would taste delicious and I wouldnt understand why, because of my cheap weird portafilter was against anything else I have seen people recommend on their recipies. I always thought that 58mm was the standard for a reason, so I was aiming to upgrade one day. I have the cheapest possible equipment Dedica with Fellow Opus and 1 euro portafilter from aliexpress and my shots taste better vs any coffee shop I have every tasted in my country. And I have tasted every coffee shop I could find.
Thanks for opening my eyes for dosing up. Still using my non-high-flow 58mm basket, but simply using ~19g instead of 17,5g and getting 1:2 shots as a result. Made my espresso so much better 👌🏻
That's why I'm not upgrading my Sage B.E. All it needs is a few accesorries, to help the dial in process, and it's a great machine for home baristas. Proper settings to the grinder and a single dose hopper also helps a lot. And freshly roasted, good quality coffee of course. At the end of the day if you like what you taste, you reached your goal. It's always, however, good to follow your videos Lance. Lot's of things to learn. Thank you for your dedication and experimenting.
I have a 51mm Pf on my Delonghi EC155 with a few mods (steam wand and depressurized bottomless pf), and I know lots of people who love the Lucca, which has a 53mm pf. I can totally agree with the findings in this video. I always felt like I had more body and better extraction overall. It also helps the pucks come out cleaner, which is a great bonus.
My reason for choosing 58mm was that at the time, it had the most options for upgrades and accessories from baskets to puck screens and paper filters and tampers, portafilters, funnels, etc. And the used market made entry cheap. Seems that the scene is expanding though, which is good. Have to consider options in the future if/when the time comes.
If the ability to grind coarser is one of the main driving force of this experiment, I wonder using the pressurized basket that is often included in entry level espresso machine can give (approximately) similar result. 🤔
The one thing a deeper puck gives you that a pressurized basket won’t is the puck’s self-filtering ability. I like Lance’s conjecture that the puck itself is pulling some of the bitterness and astringency out of the shot. Look forward to some gas chromatography data on this!
You are doing amazing work, thank you! This video helped me improve my daily espresso.. Seems like every other video you release is mind blowing!! Super impressive
I think this is interesting to say "hey, lower diameters are different, not necessarily worse." I would love to see you dial in for best taste with both and see how that concludes. How do the recipes differ, and how do the results differ?
Something I personally just realized by watching a this video. I have the Timemore Sculptor 078s grinder, and even with low roast coffees I have never had to dial below the number 1 on my espresso machine. So I have never had to take it apart and recalibrate it either. The reason for this is is likely that my machine is a La Spazialle Mini Vivaldi II, which actually has a deeper but smaller diameter portafilter basket at 53 mm. This enables me to grind my coffee just a tad courser than the standard shallow 58 mm basket to get the proper shot. So far it has been a perfect match and I am getting much better tasting coffee than I did out of my $900 Eureka Atom grinder.
I still use my stock Breville baskets, they gave me single shot and double shot, the single shot is that shallow conical shaped one, and double is deeper straight edge one. I now know why they made it conical with less hole, it is to make setting up single shot easier with same grind setting as the double shot basket. I noticed that when I make the same recipes, same dose size, same grind size, pulling 2 single shots for each cup always tastes different than pulling 1 double shot into 2 cups. I came to conclusion that deeper basket is my favorite, it always give better extraction and more margin somehow, but I didn't think much about it of how and why that is the case. lol Your video is very useful getting in depth with depth of basket of how and why it affected extraction. Thank you.
Thank you Lance. Very good. If you read the history of the standard distance between modern day train rail tracks (which is an odd one, 4 feet and 8.5 inches!?) you will see that it dates back to the distance between the wheels of Roman Chariots made to fit two horse arses! No joke! Later on horse wagons used the same measurements so wheels can fit groves on the first roads dug by wheels of Roman Chariots! People who built those horse wagons used the same jigs and tools to build mining wagons, then first road tramways and subsequently trains! It organically became a norm even though it doesn't have any practical application for the modern day equipment! So thank you Lance for debunking and challenging the norm! That's brave 🥰
Got my first coffeephile equipment back in 2013 and the first 3 things i learned is get single origin fresh roasted coffee, first drop @ 6-7 sec, last drop @ 25-30 and the biggest basket i can find, so got 24gr. Using a 7gr or 12 gr leaves no room for error and is less coffee, I ended up throwing them all in the sink. Some guy came up with this 58mm thing and everyone was like ... ok.
Next Video from Lance will be ideal particle size based on bed diameter. I hope anyways. I seriously enjoy these videos, Lance. While some will say it's unnecessary, by deepening our understanding in espresso, we come closer to good coffee
I've noticed from using an original flair exclusively for years that flow rate seems to effect the overall taste the most. Particularly steady flow. Seems like this confirms my hypothesis.
I'm still pretty new to espresso and very much learning. We have a Breville Oracle which has a 58mm basket, and for a while that was my only data point. I've had good and bad shots with it, as any newbie would. More recently, we picked up a Flair Pro 2 for when we're out camping, which has a 46mm basket and even with a 16 gram dose which is on the low end for the Flair Pro 2, the puck is notably deeper than the pucks of the 58mm Oracle. While there are a load of variables at play here, I have noticed that once I got the hang of the Flair Pro 2, I can seemingly get better shots far more consistently, even with the inherent variability of a manual lever machine, and needing to preheat the brew chamber manually. I might even go as far to say that I can get better shots from the Flair Pro 2 than I can get from the Oracle at all, but that might just be that the window to hit a good shot is smaller with the Oracle, perhaps due to the pressure profile and thinner puck depth. Not really concrete evidence of anything, but anecdotally, I do think there may be some real truth here, and I will definitely start playing around with deeper puck beds on my Oracle.
Wow, Lance deserves something big in espresso to be named after him for centuries to come! Also I want 49mm dual boiler now, even though I know I should not buy anything new as you stated...
A few months ago i stopped using an ims high flow in favor of a traditional tapered basket for added puck depth/less headspace. Easier to dial, easier to knock out, less coffee used, and better body, which is what I was looking for. I tend to prefer medium/dark w robusta so my point could be moot in these modern times but definitely interesting to see a bit of the traditional style bleed into the modern one. Thanks for the video!
Thanks for the amazing video Lance! You are awesome! I was thinking between Gaggia Classic Pro + Baratza Encore ESP Vs Breville Barista Express and was leaning towards the Gaggia solely for the 58mm, well this changes it all!
I made such good choices with starting with coffee, because the more i watch stuff, the bigger fan i am of my choice of the aeropress (and aeropress go) and my recent purchase, the flair classic. Just tried went up from 15 to 17grams , a bit coarser then i thought i had to and pulled the loveliest shot i have ever done on it, even with cheap, darkroasted espresso beans (to experiment with)
This couldnt have come at a better time! Just today i was pulling shots of a light roast with a 17g 58mm and decided to switch to my 24g basket which is considerably deeper, i only did it because i wanted a slightly higher volume of espresso using the same ratio and was suprised that the shots were tasting better every time, much sweeter and more velvety :)
The scientist in me says if narrower and deeper gave a better result, keep going until it's no longer better. You might end up with something crazy like 1/2 inch wide and 3 inches deep being optimal. The traditional aspect ratio is probably mostly for practicality.
Thanks a bunch, Lance, one of your best videos ever. A lot of experimentations awaits with aspect ratio as a variable. I understand that I don’t have to, but I’m very tempted to get this stepped basket.
