Yorsh

Yorsh (Ёрш, lit. ruffe, a little spiky fish), also known as mora grogg, is a Russian mixed drink consisting of beer thoroughly mixed with an ample quantity of vodka. It is traditionally drunk in a social setting, typically with a toast followed by downing a full glass of it at one go. It is commonly consumed in Russia. The term is colloquially used similarly to the "jungle juice" in English to designate an alcoholic mix of incompatible ingredients.

Vodka is a neutral spirit which does not greatly alter the flavor of the beer, but does greatly increase its alcohol content.

Probably the first evidence of presence of such a mix in Russian drinking culture is the Tale of Woe and Misfortune, an anonymous 17th-century poem. The early version of yorsh described there included a precursor to vodka, Хлебное вино, however.

The total amount of alcohol in the traditional version is not very high (but the kick from the mix is unordinary): a pseudonymous author of the book on the home-made libations suggests mixing 50 grams of vodka with 200 grams of beer. For a heavier "Chpock" (Чпок, an imitation of the popping sound), a more potent mix of just 50 grams of beer to 100 grams of vodka is suggested. The name of the latter drink is related to the way of mixing: after pouring both liquids into a glass, it is supposed to be covered with a palm of the hand, turned over and hit against the knee, producing the desired sound. For a full effect consumption is supposed to be completed quickly, while the bubbles and the foam are still present.
