Kvass is a traditional Eastern European fermented beverage commonly made from rye bread. Here, nutrient-rich beets are used to create a briny, probiotic-packed beverage that boasts many health benefits. The fermentation process unlocks key nutrients and makes them more available for your body to absorb. Choose local, organic beets, if possible, and leave the skin on—it contains naturally occurring bacteria and yeast from the soil that will drive the fermentation process. The introduction of salt allows the good bacteria to proliferate, which keeps the ferment safe. Enjoy beet kvass as a lower-sugar alternative to beet juice or mix it with mineral water, lemon juice, and a dash of bitters for a refreshing mocktail.
