badbeer 434:
Do we actually even know that Dave is 29%? Was it tested by a lab, or was it incorrectly assumed to be 29% based on how much it was condensed?

There is no way Dave was 29%... likely closer to 18-20%.

Err based on everything being said here wouldn’t the variance put Dave more in the range of 23-30%? I’m sure Alan is going with the high side so at most 30 surely. But would it really be off more than 9%. I would think variance would be closer to 6%.

No, because the concentration of alcohol in the frozen substance gets higher and higher the more you freeze. Freezing off 2/3 of a 10% beer means the maximum possible you can have is 30%, but he obviously wouldn’t have even close to that. In reality one would assume his numbers to be closer to something like 70% concentration increase in the first 50% frozen off (up to 17%), and then maybe 30% in the next 1/3rd, giving him 22% or so.

Thats actually what I was thinking. 22% if he is assuming 28 or 29% is about 6%. 22 or 23% sounds about right. I don’t think it would be below 20% though.

It won’t be for a couple of weeks, but we will have the answer. It turns out one of the science types in my homebrew club has the equipment to measure alcohol content in his home lab. We aren’t going to have the time to get together for the 4 hour test until after the 4th, so donít expect the results anytime soon.

All prognostications welcome, I’m going to say 20%+.

I say 75% abv. Why not aim high?

i’m betting it’s less than the base beer

Do you know what technique he uses for determining it? There are some that will work, and some that won’t.
