BJCP 2015 Guideline

Strong European Beer Eisbock

BJCP 9B

BJCP 2015 9B Eisbock example
9B - Eisbock

Aroma

Dominated by a balance of rich, intense malt and a definite alcohol presence. No hop aroma. May have significant malt-derived dark fruit esters. Alcohol aromas should not be harsh or solventy.

Appearance

Deep copper to dark brown in color, often with attractive ruby highlights. Lagering should provide good clarity. Head retention may be moderate to poor. Off-white to deep ivory colored head. Pronounced legs are often evident.

Flavor

Rich, sweet malt balanced by a significant alcohol presence. The malt can have Maillard products, toasty qualities, some caramel, and occasionally a slight chocolate flavor. No hop flavor. Hop bitterness just offsets the malt sweetness enough to avoid a cloying character. May have significant malt-derived dark fruit esters. The alcohol should be smooth, not harsh or hot, and should help the hop bitterness balance the strong malt presence. The finish should be of malt and alcohol, and can have a certain dryness from the alcohol. It should not by sticky, syrupy or cloyingly sweet. Clean lager character.

Mouth Feel

Full to very full-bodied. Low carbonation. Significant alcohol warmth without sharp hotness. Very smooth without harsh edges from alcohol, bitterness, fusels, or other concentrated flavors.

Overall Impression

A strong, full-bodied, rich, and malty dark German lager often with a viscous quality and strong flavors. Even though flavors are concentrated, the alcohol should be smooth and warming, not burning.

Ingredients

Same as doppelbock. Commercial eisbocks are generally concentrated anywhere from 7% to 33% (by volume).;

Comments

Extended lagering is often needed post-freezing to smooth the alcohol and enhance the malt and alcohol balance. Pronounced "ICE-bock."

History

A traditional Kulmbach specialty brewed by freezing a doppelbock and removing the ice to concentrate the flavor and alcohol content (as well as any defects).

Commercial Examples

Kulmbacher Eisbock

Style Comparison

Eisbocks are not simply stronger doppelbocks; the name refers to the process of freezing and concentrating the beer and is not a statement on alcohol; some doppelbocks are stronger than Eisbocks. Not as thick, rich, or sweet as a Wheatwine.
