The method

Step by step

  1. 1

    Preheat your oven to 150°C (300°F).

    About 5 min

  2. 2

    Spread the rye bread cubes on a baking sheet.

  3. 3

    Toast the bread cubes in the oven for 15-20 minutes, or until they are deeply browned but not burnt.

    About 20 min

    Cook’s note: Darker toast produces a richer kvass flavor.

  4. 4

    Remove the toasted bread from the oven and let it cool completely.

    About 10 min

  5. 5

    Place the cooled toasted bread into a large, clean glass jar or pitcher.

    Cook’s note: A 2-liter capacity is ideal.

  6. 6

    Heat the water in a saucepan until it is warm to the touch, about 40°C (105°F).

    About 5 min

    Cook’s note: Avoid making the water too hot, as it can kill the yeast.

  7. 7

    Dissolve the granulated sugar in the warm water, then stir in the active dry yeast.

    About 1 min

  8. 8

    Pour the yeast mixture over the toasted rye bread in the jar.

  9. 9

    Add the optional fresh mint leaves and raisins to the mixture.

    Cook’s note: Raisins can help kickstart fermentation.

  10. 10

    Cover the jar loosely with a clean cloth or lid, allowing air to circulate.

    Cook’s note: Do not seal tightly, as fermentation produces gas.

  11. 11

    Let the mixture ferment at room temperature for 12-24 hours.

    About 12 hr

    Cook’s note: Fermentation time varies with temperature; taste periodically to check for desired sourness.

  12. 12

    Once the kvass has reached your preferred level of sourness, strain the liquid through a fine-mesh sieve into a clean bottle or pitcher.

    About 2 min

    Cook’s note: Discard the spent bread and any solids.

  13. 13

    Seal the bottle tightly and refrigerate the kvass immediately.

    Cook’s note: Chilling slows down fermentation and improves flavor.
