Beet kvass is the brine from fermented beets (beetroot). It combines the benefits of beets with the benefits of fermentation! Beets contain vitamin B9 (folate) and vitamin C, plus iron and a variety of minerals that are necessary for proper nerve and muscle function and for healthy bones, liver, kidneys, and pancreas. Beet kvass is easy to make, and a shot of it is a great morning tonic and organ cleanser. If you buy organic beets and ginger, you don’t even have to peel them. This recipe works well in a half gallon (2 L) Mason jar.
