Kir (keer), or cassis au vin blanc (cass-ee oh vahn blawn) as it is also called, is a refreshing wine drink popular all over France.
As its alternative name suggests, it is a mixture of what the French call creme de cassis, or essence of blackcurrant juice, and white wine – preferably the white wine of Burgundy where the drink originated. While the proportion of one to the other is mostly a matter of personal taste, usually it is ABOUT 1 tablespoonful of cassis to
4 fluid ounces of wine.
Kir is generally drunk as an aperitif.
