Beet kvass is an old digestive remedy and is very easy to make. To drink, pour out a serving and enjoy it straight, or dilute with equal part of filtered water or mineral water. Drinking too much at once can provoke a detoxification reaction. So a suggestion is that the first time you drink it, you can drink 1 tsp of beet kvass, diluted with an equal amount of water, once a day for several days, and increase the amount you take slowly. You can add to it your favorite spices or aromatic seeds, or some grated ginger as well.
