COARSE Ground Aeropress? Game - changer! 

According to a new study about making espresso, there is a sort of point of no return when going finer, after which the flavor gets weaker rather than stronger, and this is apparently due to a „channeling effect“. With a coarser grind, more water can pass by more of what‘s in the puck, thus extracting from a greater volume of beans altogether. With a (too) find grind, the water being pushed through the puck under pressure has to sort of fight its way through more, thus leading to channels/rivulets where most of the water penetrates the puck, thus extracting only the beans passed by, and sort of leaving a large amount of the puck unextracted. This is my layman‘s way of stating the findings of the study, but it makes a lot of sense...AND finally explains why my own experience with both the AeroPress and the Staresso gave me a less flavorful cup when I went sort of fine (pre-espresso fine, but finer than coarse). When I backed off a bit, the flavor improved considerably. So it seems you guys are confirming the same phenomenon.

It is great and all but a 7 minutes video talking about coarser grind without showing what you mean by coarser grind? It would have taken you 3 seconds or something....

I was hoping to see photos of the both grinds.

How is this helpful? You are presenting a result, without giving us any initial data.What type of coffee roast? What temperature? Brew time?

Best way to use Aeropress for multiple cups of coffee. Multiply the amount of coffee used by the cups needed. So for example, I use 14gms of coffee for one cup so to make 3 cups I add 42gms of coffee and then fill up with water. Express your coffee mixture to a jug when finished brewing and then add three cups of hot water. Great coffee for you and two of your friends.

Interested in trying the coarse. The video would be imo way more informative if you took some shots of coarse and fine ground coffee and compared them side by side before you started brewing. I'm a coffee amateur so when you say 'coarse' I have no idea how it should look like...

Hands down the best method for brewing a single cup of coffee! I'll have to try the coarse.

There's no mystery to it really. The fine grind needs to be constantly mixed, otherwise they'll all clump down and settle instead of contacting the surface of the water.

Kinda painful that they both said it’s a pain only being able to make 1 cup at a time when you can make a litre at a time (use 4 scoops of beans, fill to 4, split across 4 cups and top up with water)

I'm very late to comment, but just found this. I managed a coffee house for years, and am super picky, and was unsatisfied with the Aeropress until I accidentally used a grinder set to a courser level. It was a revelation. I now keep the grind on slightly courser than medium, and it's perfect.

Just wanted to chime in as another person that does dilute the concentrate to make multiple servings of coffee. For whatever reason, I get the feeling that people generally don't think this will yield good results, but it does in my opinion! Also, the coarse vs fine grind thing is interesting, but something that Alan Adler mentions in the Aeropress movie, is that some of these championship recipes call for a lot of coffee to produce a single cup. A common coffee to water ratio I've seen for various methods, including Aeropress, is around 60 to 75 g coffee per liter of water, whereas some Aeropress Championship recipes have been in the range of 100 to 140 g of coffee per L of water such as the coarse grind recipe used here. So, while interesting, might not be economical or practical to use a recipe that results in going through a bag of coffee twice as fast.

It's great to see you guys enjoying your brew ☕☕☕ Great video♨ You inspired me to go and experiment a little bit more with the AeroPress! Happy Brewing🔥🙌

So all the methods and then just back to what inventor Alan Adler said about grind size and method. Amazing.

So I just tried the coarser grind you recommended and my god did it make a difference. You guys are my coffee gurus

Have I got this right? "The coarse ground method wins because it uses over twice the amount of coffee (35g) than the medium/fine method (16g)." The coarse method wins because a relatively small amount of water (200ml) is steeped in an unusually large amount (35g) of coarsely ground coffee. The coffee is under-extracted, but that's OK because there's so much of it being used that you're effectively quickly stealing the best part of the coffee's essence and then whisking it away in hot water before it can be fully, or even over extracted, potentially spoiling the flavour. I'll try this method one day and I'm sure I'll agree with you. But man, about 60g per litre is where I draw the line. By my calculations, 35g of coffee brewed with 200ml of water (the Aeropress's max volume) equates to 175g per litre. Have I got that right or am I just tired? Ha, if I'm brewing at a ratio of 175g per litre, it had better be the best coffee I've ever tasted! My new life goal: to be able to afford to brew at 175g per litre 😂.

I noticed this as well…I was using a fine grind and for some reason the taste wasn’t coming out very well. As soon as I changed the grind to something a little more coarse the flavor ended up becoming bolder and better which really surprised me.

I always wonder about the paper vs metal filter argument as far as environmental impact . Especially when it comes to resources used in and during production

I've also used a cloth filter. Cutting up an old T-shirt gives you a large supply of Aeropress filters.. One or two of them together works pretty well, and then you don't have any paper to discard.

I double the coffee and make 2 cups at a time. Also I reuse my paper filters. Just a rinse and dry.

Just thought I would give this coarse recipe a try, I have been doing finer and 18g previously, and straight off a excellent cup of coffee. Thanks looks like this is my new recipe for now.

The coarse ground thing works because there is a point in the neighborhood of underextracted where the coffee is indeed underextracted, but it still tastes good. I don’t know why. This is also the main principle behind many competition recipes.

I forgot to readjust my grinder from a french press grind and it was amazing! Can't wait for cold brew/iced coffee season.

Would you not over extract if you use a medium fine grind and the inverted method? I thought you were supposed to grind course for that

Going coarser and low temp brewing are the trends in Aeropress championships. Either you grind it coarser or adjust the temperature because the Aeropress retains heat

Organic chemistry tiled wall in background - any known compounds?

Thanks guys, very helpful for this coffee snob newbie.

So what was the brew time for the course grind? And did you do a bloom first?

What was your coarse grind receipy?

What is the recipe? What is the grinder? What is the grind setting? What are the beans? What is the water?

Getting mine tomorrow. My mill is currently set for drip coffee. I think I'll start with that grind.

Where can I get that crema mug?!

cool vid! would recommend a double blind protocol at very least if u do it again.

They have a new"travel" version. The paddle? That is another part of the briliiant design that is the perfect length so it wont scrape the bottom with the paper filter but still agitate the coffee AND it rests in the brewer without toppling it over or leaning on one side like a spoon might. IMO, the best invention ever in the coffee industry. Coarser grind? With the Aeropress I get a grapefruit like acidity on some coffees that I'm not fond of. I do use a coarser grind than what I used to for a V60 and prefer it over the usual medium fine grind.

You don't have to flip it just put pour the water put the plunger so to seals the areopress. The air pressure will keep the water in the areopress

Always read the comments before hitting PLAY. This way we never waste our time if not needed. Thanks to the comenters below.

Where's the mug used in the mug from?. Somehow a mug with Crema written on it seems like peak Coffee obsession and I want it.

Surely this is all dependent on brew time, water temp, roast, etc? More info needed here please.

But if you’re wanting to achieve the most espresso like end product, should you still do a coarser grind?

I used a metal filter for a while... For this I kept going finer and finer grind, just to stop the water from flowing right through. But then I get fines flowing through... Takes a while to find the right size. Also if I can be fast and get the plunger in, it helps slow the water from just rushing right through. Paper filter is better, but I am a tree hugger so I only use them once in a while, I also rinse and reuse them a few times

Good to know!! Looking forward to trying this when I receive my Aeropress 🙏🏼 thanks guys ;) enjoying your content!

Have you read the manual? You can easily make 4 cups at once.

To all the people commenting and compiling about them not telling you what grind size. That’s not the point. The point is however fine you’re doing it, try going more coarse and play with it until it’s right for you. It’s gunna vary from one grinder to the next and depending on what beans you have as well as personal preference. So it doesn’t matter what they did. The takeaway is whatever you’re doing, make it more coarse and it will be better

Smoother because you actually extract less coffee from the grounds .

This guy is cool. Very cool.

Is "Coarse" coarser than drip or coarser than espresso, like adler it prefers?

This is just a theory but these beans might contain some slowly extractable taste material that masks some faster extracting good tasting material. In that case more extraction means less taste after the point where the goood tasting material has finished extracting

Pro tip: you can reuse your paper filters. Just rinse them after use. I use mine for a whole week before I toss it.

So rookie! love it at the same time

It's fascinating how there's like a million ways to make coffee with this thing and no consensus on what actually is best. What I would find interesting is that if you have 1 person specifically judge, can you derive a procedure that is optimal for that person's preferences, or will there be multiple vastly different routes to make a cup of coffee that the individual will not be able to distinguish one as superior?

Prismo filter for the win!

I make concentrate in my Aeropress. Using 40grams of coffee then filling the vessel full of water, I get 4 cups out of that. One serving of concentrate is about 40grams, and I add 150ish grams of water to make a cup of coffee. It has made for a much more enjoyable experience, I only have to make one batch per day instead of several.

Interesting ...

Best espresso recipe with aeropress by far: 18,5 grams (13 clicks) 60 grams water Inverted method 20 second stir 2 min steep Flipover and press harder than normal (not too hard)

I've tried 4.... Doesn't work....two at once tops

I just use the larger Aeropress and treat it exactly like any old press pot. No need for watering down calculations.

the inventor himself said not too fine. not espresso fine, just somewhere in the middle of espresso and drip grind.

Hmmmm interesting

When did using paper become bad for the environment. It is a renewable resource. You do realize that they have to dig that metal out of the ground and then they have to smelt it. I do realize that everyone claims that metal is somehow better for the environment in every video I've ever seen.

How did I find this shot?! I'm about fed up with bland tasting with fine or medium fine gind. Then out of desperation I just winged it for something new. For taste. So my hand grinder has a dial. 0-1 full turn is med fine. Did that for 30 second. I've never went over 1.5 turns. But I did go to 2 turns at 30 seconds. So I have 2 kinds of grinds. I should of just went with what u guys had. Full course grind. So I had the 2 and it was rather good. Better than fine grind. So my new game is course grind coffee. Also it really goes through the press easy. So might want to let it sit a bit. It's much better taste than find grind. Who drank my coffee.? That went down fast. Midnight drink 12:26am. Full moon sleep like a log. Zzz

Arguing about the waste of paper filters, something completely compostable and the amount of paper per cup being minimal always seems silly to me. It's not even worth expending the mental energy worrying about this when there are so many other factors that are much more wasteful than a paper filter for your morning cup of coffee. If we really wanted to go there, let's talk about the chemex papers and how much larger and thicker those are, but then again, let's not, for the same reasons i mentioned.

A blend of coarse & fine grind, then stir w paddle for 10 sec.

I can't take me eyes off that guy's earlobes flappping about like Dumbo.

How many discarded aeropress paper filters will it take to destroy the planet? Should the government get involved? Should Congress hold hearing?

Lost me at 'forgot the paddle'.

35 grams of coffee for 1 cup is ridiculous and not practical for everyday drinking.

JFK

I am ashamed to say I've never used an Aeropress.

Show us the coffee in the cup next time please. Lotsssssss if talking. Music too loud during extraction. Crema or no crema?

How about you give me YOUR recipe... THEN I'll give you mine. #smh

I imparted no information from this video. You don't give water ratios, coarseness, steeping time. Nothing. I doubt you even made two cups separately. This was the second video from you guys I watched and its the same pattern.

This video is terrible. 7 minutes video titled "COARSE Ground Aeropress? Game - changer" 0 minutes showing the grin or tips on achieving it.

You can easily make two to three cups - I have a small carafe I press into that holds two cups - I measure out enough coffee for two and it’s perfect
