Kraut juice

Kraut juice (called Sauerkrautsaft in German, Moare in Romanian or Rasol in Serbian and Bulgarian) 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.
