Yorsh
Yorsh is a Russian mixed drink consisting of beer thoroughly mixed with an ample quantity of vodka. 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.
The origins of the drink and the etymology of its name are disputed. Pseudonymous author Alkofan suggests that the cocktail was discovered by Russian merchants who, after a meal, poured all the leftover alcohol into a single vessel called "yoursh".
The total amount of alcohol in the traditional version is not very high : 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", 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.
