Bock - Eisbock

BJCP 14-D

AROMA

Dominated by malt. Definite alcohol presence. No hop aroma. No diacetyl or esters.

APPEARANCE

Deep gold to dark brown in color. Lagering should provide good clarity. Head retention may be impaired by higher-than-average alcohol content.

FLAVOR

Rich malt and concentrated alcohol. No hop flavor. Hop bitterness just balances the malt sweetness to avoid a cloying character. No diacetyl or esters.

MOUTH FEEL

Full-bodied. Carbonation low

OVERALL

An extremely strong lager beer

INGREDIENTS

Pale lager malt for pale versions, Munich and Vienna malts for darker ones and occasionally a small fraction of dark-roasted malt in those. Continental European hops for bitterness only. Lager yeast. Water hardness will vary.

COMMENTS

The process of concentrating the alcohol content by freezing may impart significant smoothness to the flavor. The effective OG range due to the freezing effect is 1.092-1.150.

HISTORY

A Kulmbach specialty traditionally brewed by freezing a Bock or Doppelbock and removing the water ice to concentrate the flavor and alcohol content.
