How to Make Kvas or Kvass


  • 1Preheat oven to 200 degrees F and spread bread cubes on a baking sheet; bake until the bread is fairly dried out, about 1 hour.
  • 2In a large pot, bring 3 quarts of water to a boil, remove from heat, and stir in bread; cover with a clean towel and let rest in a cool, dark place for 8 to 10 hours.
  • 3Pour the liquid through a fine meshed sieve, or strainer, and gently press bread to get the liquid (don't press too hard or your finished product will be cloudy).
  • 4Mix the yeast with the warm water and a pinch of sugar; set aside and let proof 10 minutes. Stir into the strained liquid along with 1 cup sugar, stirring until sugar is dissolved; cover and let stand another 8 to 10 hours.
  • 5Strain again and pour into a 1 gallon container; add raisins, cover tightly with plastic wrap and a rubber band. Let stand in a cool, dark place 4 to 5 days until the yeast sediment has settled to the bottom, leaving a clear liquid
  • 6Carefully pour the clear liquid into a clean container or individual bottles, trying not to disturb the yeast sediment. Chill well.
  • 7VARIATIONS: add 2 tablespoons fresh mint leaves with the yeast and sugar. Or substitute 2 to 3 cups of berry juice for some of the water to give it a fruity flavor. It can also be served with the yeast sediment. This gives it a richer flavor and more vitamins.
