Beet kvass has a long tradition of use in Russia, Ukraine and other eastern European countries, where it is consumed as a general health tonic. Fermenting your beets rather than eating them raw gives you all the health-boosting benefits of raw beets in a more bioavailable form — plus the beneficial bacteria and enzymes that result from fermentation. Traditionally, beet kvass has been used to boost immune function, cleanse blood, combat fatigue and treat kidney stones, chemical sensitivities, allergies and digestive problems. The Kraut & Krunch beet kvass does not use whey as a starter and is, therefore, suitable for vegans. All ingredients are certified organic or naturally grown.
