Sauerkraut (/ˈsaʊ.ərˌkraʊt/; German: [ˈzaʊ.ɐˌkʁaʊt] , lit. 'sour cabbage')[1] is finely cut raw cabbage that has been fermented by various lactic acid bacteria.[2][3] It has a long shelf life and a distinctive sour flavor, both of which result from the lactic acid formed when the bacteria ferment the sugars in the cabbage leaves.[4]
