Kraut juice
Kraut juice (called Sauerkrautsaft in German or Rasol in Serbian) is a beverage that consists of the liquid in which sauerkraut is cured. It is the juice of the vegetable itself and the pickling brine.
It is widely available in many central and eastern European countries, such as Germany and Serbia, and in the parts of the U.S. Northeast and Midwest where German immigrants settled, such as central and western Pennsylvania.
It is considered as an excellent natural dietary supplement since it`s extremely rich in vitamin C, as well as vitamins of B group, E, K, rare U and potassium (475 mg), calcium, phosphorus, sulphur, iron, copper, zinc, magnesium and lactic acid. It also contains live lactic acid bacteria. It helps normalize the gut flora and is also used as a laxative.
