I was talking to a doctor and he said around 7% ABV hits the bloodstream quicker and therefore you you get a quicker alcohol hit. Much above that figure and the body has to dilute the alcohol down to around 7% which the body can handle.
Using the alternative formula, ABV =(76.08 * (og-fg) / (1.775-og)) * (fg / 0.794), which is purported to be more accurate for high gravity beers, this beer actually could be 9.4%!
The problem would be is that 1 gallon of glycol and 1 gallon of water does not make 2 gallons of mix. Really it doesn't matter as long as it doesn't freeze.
You can just simplify it all by going with a 2:1 ratio of Water to Glycol, or 33% and 67% (vs. 35% and 65%)... which is ultimately what he did with 4 gallons of water and 2 gallons of glycol.
That chiller is huge! My Stasis unit is dwarfed by that badboy. Love brewing DIIPAs....I actually never do more than 30min boils for them. I have been using London Ale III recently and lots of post-fermentation hop additions. Big, juicy and tropical....love em! Thanks again for the great content!
Thank you for the video as always Martin. One trick I've learned with my Clawhammer brew system is if you need to cool the wort down faster get a cooler with water and ice and just drop your chiller in it while cooling wort. Cheers and keep up the great content! BrewswithCason
Thanks for the vid man. You just gave me an excellent idea of what I can do with a water chiller tower, an stc1000 and some good ole H20. This is gonna be gooood! thanks.
Personnaly i’m more intrested in the 22th category, especially barley wine, since i’m european so i’m a bit overwhelmed by all the belgian ales here haha. But i guess you are in the same situation just the other way around
You probably got your answer already but this is basic maths. Just make an equation, 2 * 0.35 = x, which can be rewritten x=2/0.35. Great video by the way, will try this one next week
17:02 missing fermentation data. Btw. whenever you have only one fermenter in a chest freezer, you can achieve accurate temperature control just by placing the probe on the outside of the fermenter with a insulating pad taped over it.
by the way martin, the amount is 3.71 gallons of water. The calculation is 2/0.35 - 2 (you minus 2 at the end as otherwise it shows how much water and glycol combined)
You have any old equipment you don't want anymore, I'd be glad to take it off your hands for free lol!! Been watching every episode since the beginning, just moved from Fayetteville. Atlantic Brew Supply was my spot to get everything. Really wanting one of those anvil cooling systems, all sold out right now! Great video!! Looking forward to seeing you brew this section with the Barleywine, also looking forward to the sours and prohibiton beers
If you ask me Martin has gone too native :-) It is bad enough this non metric Fahrenheit and Ounces nonsense. No Brit in their right mind would say "MATH". Next he will say Zee rather than Zed. You should be more grateful for the pain he must be going through to appeal to you Americans and Canadians ! Personally I would be trying to educate you all to talk, spell and measure correctly :-)
Thats the first thing I thought of it when I see at Clawhammer Supply videos.. Why wouldn’t they do that, would it effect the water flow, no.. Would it effect the balance of the lid, maybe, but with the hose pulling all the time, and squezed by pulling, both the balance and water flow effect anyway..
I LOVE Double IPAs...awesome recipe, awesome video as always! I want that Clawhammer system SO badly...but I'm eyeing up the Brewer's Edge Mash and Boil (w/ pump) for now. It's a lot cheaper, but obviously not reaching the level of the Clawhammer. Anyway, loving the series! Thanks! The American accent btw...SPOT on. ROFL
Little bit late to the party, but for your glycol - if 35% is 2 Gallons then your total amount is 2/0.35 = ~5.7. So your 65% part is ~3.7 Gallons (5.7*0.65 or 5.7-2)
More or less. I use BeerSmith to scale my recipes and everything is mostly half. The hops are slightly more than half. But honestly you won’t be far off just halving everything.
So regarding your math problem... 2 gallons is 35% of your total volume. 2=0.35X X=5.7 Your total volume is 5.7 gallons. So 5.7 minus 2 is 3.7 gallons of water. You were close.
Can also use similar ratios, same math, different reasoning: glycol/water = 35/65 = 2/w (multiply both sides by w) 35w/65 = 2 (multiply both sides by by 65) 35w=2*65 (divide both sides by 35) w=2*65/35 And then you're just like Adam said, just a different way of thinking about it.
even simpler I think. Since it is only a ratio between two substances.. 65/35 = 1.86. So you will have about 1.86 more gal of water per gal of glycol. 1.86 * 2gal of glycol = 3.71gal water.
This beer sounds great especially the Antipodean hopping profile. Can you advise what the ABV /OG would be if I dropped the dextrose as I would prefer a lighter beer I can actually drink. Does the dextrose addition effect more than the ABV? I.e Is it crucial to the mouthfeel / balance of the beer and lighten it. Great video as ever !
I just did 6 gallons of water and 2 gallons of glycol. I can get down to 25 degrees without a problem, and I haven't found a reason to go any lower. I usually keep it at 27 degrees and that gets everything done with 12 gallons of beer split between two fermenters. Is that Oasis playing very faintly in the background?
Temperature controller probes must be put in the vicinity of the fermenting wort. I put mine inside the fermenter, in the wort. Another way would be to stick the temperature probe on the side of the fermenter, below wort level, with insulation over it. Otherwise it will not give accurate readings of the temperature of the fermenting wort, which always rises during fermentation. That bottle with the probe only measures the temperature inside the chest freezer, not the rising fermenting wort temperature.
One of the best videos you ever made Martin.. Really enjoyed to watch it.. A few more adjustments would make it perfect.. Btw, too many types of hops makes the flavor a bit confusing I think.. Something like 3 style complementing hop would make a more promounced aroma and flavor from each hops.. For this beer, even just do Motueka only would make a nice and interesting beer😃🍺🍺
yeah metric is just crazy hey. boil is 100 and freeze is 0. so hard to do the calculations. id much rather get out my calculator when trying to work out what 100mm is. oh its 3.937008 of an inch. much easier :D
I'm drinking homebrew in my mancave whilst binge watching your videos. I've got a tonne of cascade and amarillo to use so I think it's a double ipa next. What would you recommend the max corn sugar to use in the grain bill, about 10%? I want it strong without it tasting boozy
It’s 3.71 gallons. To figure it out in future divisions how much glycol you have bye 35 then times that number bye 65 and that’s how much distilled water you should add
I was wondering, how are you going to brew the sour styles that need longer aging? Will they be skipped at first, or did you already start them when you started the challenge ?
The math is as follows 2 gallons is 35 of what x is to 65 2 x 65 / 35 = 3,714 gallons or 475,43 US fluid ounces assuming you have US gallons to start with. 4 gallons of water gives you a 33% mixture.
So, Martin do you have a lot of brits coming over? I have a similar setup to you. A SS brew bucket that as the FTSS system and tilt and I just made a glycol chiller but I haven’t used it yet. California right now is 70 during the day and 55 at night. So I am in between needing cooling and heating. But what did you think about using the glycol chiller? Did it make a difference?
To solve this problem, we can use the concept of proportions. If 2 gallons represents 35% of the mixture, then we can set up a proportion: 2 / x = 35 / 100 where x is the total number of gallons in the mixture. To solve for x, we can cross-multiply and simplify: 2 * 100 = 35 * x 200 = 35x x = 200 / 35 x = 5.71 Therefore, the total number of gallons in the mixture is approximately 5.71 gallons. To find the remaining percentage of the mixture, we can subtract the percentage of the 2 gallons from 100%: 100% - 35% = 65% So the remaining percentage of the mixture is 65%. If the total number of gallons in the mixture is approximately 5.71 gallons, then 65% of the mixture is: 0.65 * 5.71 = 3.71 gallons (rounded to two decimal places) Therefore, the remaining percentage of the mixture is approximately 3.71 gallons.
On the whirlpooling of your hops........I find myself clamping my wort return line directly into the hop basket. Not sure if it helps or not, but figured it could'nt hurt!
For what it's worth, I've added my hops outside the basket and then put the return line into the hop basket. In a 20 - 30 minute whirlpool it seems to filter almost all of it and I feel like I'm getting better contact that way.
Ratios my man, easiest way to calculate. 2 gallons/0.35 = x gallons/0.65 X = 3.71 gallons distilled water I'm a pharmacist though and this is the type of calculation I have to do all the time so it may have seemed more intuitive to me.
Where are you finding these tasting partners? Your videos are a 10/10 until the grand finale tasting part and it falls flat. I’d like someone who can speak on real tasting notes please. Your dad is the man. I’d rather you just have him do all the tastings.
Just for future reference, Motueka is pronounced: MOT (like not) - CHEW - ACHE - ER. It’s named after the place just outside of Nelson, on the South Island. Where Nelson Sauvin comes from. It’s a beautiful place with beautiful hops. Also, another great vid. Lacking some otter though 😉
If 35% of the total volume (x) equal 2 gallons of glycol: 0.35(x) = 2 x = 2/0.35 x = 5.71 gallons total volume Therefore, 5.71 - 2 = 3.71 gallons of water.
Is it just me, or is that glycol chiller a bit overcomplicated? Just put a bucket of glycol in your freezer, and run a pump with your inkbird or whatever and that's it. I'd expect a whole lot more from an expensive glycol chiller as this one in the video.
That's not a hard calculation 😂 2 gallons is 35% of the total amount of liquid. This makes 1% of the total amount 2/35=0.0571 gallons. Multiply that by 65 and you get the 65% number you were looking for =>3.71 gallons
