BJCP 2008 Guideline

Bock - Eisbock


BJCP 2008 5D Eisbock style example
5D - Bock / Eisbock



An extremely strong, full and malty dark lager.


Eisbocks are not simply stronger doppelbocks; the name refers to the process of freezing and concentrating the beer. Some doppelbocks are stronger than Eisbocks. Extended lagering is often needed post-freezing to smooth the alcohol and enhance the malt and alcohol balance. Any fruitiness is due to Munich and other specialty malts, not yeast-derived esters developed during fermentation.
