14. BOCK
14D. Eisbock
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.
Mouthfeel: Full-bodied. Carbonation low.
Overall Impression: An extremely strong lager beer.
History: A Kulmbach specialty traditionally brewed by freezing a Bock or Doppelbock and removing the water ice to concentrate the flavor and alcohol content.
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.
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.
