Welcome to the homeBBBrew board!
Like the BBB, the homeBBBrew board is not a club, just a place to talk about making beer. Is there a swap you would like to see happen? If we can find a few others who have something similar then lets do it!

NO SPECIFIC REASON FOR THIS LINK...
I just really like the work levifunk is doing!

Angels share/evaporation
for some reason I had this thought last night while sleeping (I blame the cooking shows that always say the alcohol will cook off when using wine)....does the alcohol in a barrel evaporate at the same rate as everything else? For example, if I have a 60gallon barrel of 5% lambic, which evaporated 5 gallons.....do I then have 55 gallons of 5% lambic? Or 55 gallons of something with a higher/lower abv. I've been operating under the assumption that it's the same, or close enough to not really bother with adjusting the beer I top off the barrel with.

Re: Angels share/evaporation
I wish I had an answer Dan - that is a really great question. I wanted to ask though, is that level of evaporation out of a keg something that could really happen? Or is that just an example to dial in your question?

Rate of water evaporation depends on humidity of the air. If 100% humidity then no water will evaporate, only alcohol.

Re: Angels share/evaporation
From what I've read it's similar enough to not really matter. I don't think Jean Van Roy is doing any lab testing to see just what evaporated and replacing it with wort that would balance it out, so I don't think there's a reason to worry about it.

In fact in general I don't worry about anything doesn't affect the taste of the finished product. When I have a good lambic, any thought of how much alcohol in it is far out of my mind.
