Does the word “Eisbock” make you think of ice cream? Well, that’s no coincidence.

Today, we invite you to discover Eisbock, a distinctive style from the Bock family, a 19th-century German beer style. Although it originated from a brewing mishap, this rich and powerful beer has since carved out a place of honour in the world of beer, especially among those who appreciate bold flavours.

History of Eisbock

You may already be familiar with Bock, a bottom-fermented lager dating back to the 16th century, known for its Bavarian roots and unique brewing method. This family includes robust beers like Doppelbock, Maibock, Dunkles Bock, and of course, Eisbock.

The story of Eisbock began in Kulmbach, Bavaria, in the late 19th century. After the invention of Doppelbock, a young brewer left a vat of beer outside overnight in winter. The cold froze most of the water, but the alcohol remained liquid. As punishment, he was told to drink the unfrozen portion. To his surprise, it was delicious—concentrated, sweet, and warming. Thus, Eisbock was born: a stronger, richer version of Bock.

Did you know? Eisbock is technically illegal in the U.S. because its production involves a form of distillation, which requires a special permit and taxation scheme. Most breweries there cannot label or market true Eisbocks as beer.

The birth of a style

The Eisbock brewing method involves freezing the beer, separating the ice from the remaining liquid (concentrated alcohol), then warming and bottling it. This process is both time-consuming and expensive, which explains the higher price point of many Eisbock beers. The name itself comes from the German word “Eis” (ice) and “Bock”.

The resulting beer is intense and full-bodied, with an alcohol content ranging from 9% to over 14%. Many breweries now compete to brew the strongest Eisbock possible, with some reaching over 33%. Creating an authentic Eisbock requires balance, technical skill, and flavour complexity—without adding external alcohol.

The notorious Snake Venom, marketed as the strongest beer in the world at 67.5%, is rumoured to contain added ethanol. While impressive in strength, it deviates from the traditional Eisbock method, raising questions about whether it should be considered a true beer.

What does an Eisbock taste like?

Eisbock typically ranges in colour from deep brown to near black. It delivers an exceptionally rich, warming flavour profile with notes of dark fruits (plums, raisins), wood, and roasted malt. Low in hops, it retains the clean character of a lager but introduces caramel, chocolate, and toast-like elements.

How to taste an Eisbock?

For optimal tasting, Eisbock should be served at around 16°C in a brandy glass or snifter. This shape helps capture and concentrate the aromas while preserving a creamy head. Gently warming the glass by hand enhances the sensory experience.

Pairing suggestions include slow-cooked pork in a fruity sauce or aged cheeses like Gouda. Eisbock also complements rich desserts such as dark chocolate cake or crème brûlée. But don't hesitate to sip it on its own to appreciate its intricate nuances.
