Malt beverage used to add acidity and sour taste to soups.
It is a sour fermented drink that is made from a mixture of wheat bran, rye flour, and water that has been left to ferment for several days. During the fermentation process, lactic acid bacteria grow and multiply, giving the drink its distinctive sour taste.
Raureni Bors Acru is often used as a base for traditional Romanian soups and stews, such as ciorba and borscht.
