Eisbocks are produced by freeze concentration.

Eisbocks are produced by freeze concentration.

• A. Freeze concentration
• B. Pasteurization
• C. Distillation
• D. Filtration

Answer: (A)

Freeze concentration is the method used to make eisbocks. By freezing beer, ice forms from water and can be removed, leaving behind a liquid enriched in alcohol and dissolved flavor compounds. This selective removal of water concentrates the beer without distilling, producing a stronger, malt-forward beer. It’s different from pasteurization, which uses heat to kill microbes; distillation, which separates and collects alcohol as vapor; or filtration, which removes solids. Eis bock takes advantage of this physical separation to increase strength and body while keeping it beer-like.
