How to Choose Kvass
Quality kvass is naturally fermented and has a lightly sour, tangy aroma; it should be distinguished from carbonated drinks made only with flavoring and carbonation that merely taste like kvass.
- It should be naturally fermented, not merely a flavored soda
- It should have a lightly sour, tangy, bready aroma
- It should have been kept refrigerated and be within its date
How to Store Kvass
Because kvass is a live fermented product, it keeps for a few days in a sealed bottle in the refrigerator; fermentation continues, so pressure may build up in the bottle, which should be opened carefully.

How to Make Kvass
Toasted rye or dark bread slices are placed in hot water, then sugar and yeast are added; after fermenting for a few days, the mixture is strained, bottled, and chilled before serving.
