Someone in my club has said "freeze distilling is illegal!!11!1!"
Just like im sure all of us stay under our 200 gallon limit per year.
TBH, I have never made an eisbock and I don't know the process. Sounds like the beer is brought down to freezing and then ice is removed when it forms to strengthen the beer... something like that. Doesn't really sound like 'distilling' to me but what do I know.
