What is an “ice” beer?
- Sam J., Bucks County, PA
Interestingly enough, the name is almost backwards. There isn’t anything additional in an ice beer. Instead, ice is actually removed. After finishing the beer itself, it’s brought down to temperatures below freezing and “fractional freezing” occurs. Fractional freezing is the process of separating two liquids with different melting (or freezing) points. In this case, water freezes long before alcohol, and the beer begins to form ice crystals. The ice crystals are then filtered out of the beer, leaving a stronger, higher ABV beer. It is, in fact, a type of distillation known as “freeze distillation.” Ice beers are actually partially distilled and find their pedigree in German Eisbock beer. These beers, made by fractional freezing of doppelbocks, create beers that range from 9% to 43% ABV. Read more…
