Which process is used to create eisbocks?

• A. Freeze concentration
• B. Distillation
• C. Fermentation
• D. Aging

Answer: (A)

Eisbock is produced by freeze concentration. A strong beer, typically a doppelbock, is partially frozen and the ice that forms (mostly water) is removed, leaving a more concentrated liquid with higher alcohol by volume and a richer malt character. This relies on water freezing while ethanol remains liquid, so removing the ice increases concentration without any distillation of alcohol. Distillation would separate alcohol by vaporization and isn’t how eisbocks are made in brewing. Fermentation or aging alone doesn’t concentrate the beer after fermentation; they change flavor or alcohol content, but not by removing water to boost strength.
