Discover how to make Kvass, a traditional fermented beverage made from rye bread. This easy-to-follow recipe captures the unique, tangy flavor of this ancient Slavic drink. Perfect for enjoying chilled or using as a base for refreshing summer cocktails. Learn the step-by-step process to create your own homemade Kvass with simple ingredients.

Ingredients:

- 1 loaf of rye bread (preferably stale or toasted)

- 10 cups water

- 1 cup sugar

- 1/2 cup raisins

- 1 tablespoon active dry yeast

- 1/4 cup lemon juice (optional)

- Fresh mint leaves (for garnish, optional)

Instructions:

Prepare the Bread:

  - Cut the rye bread into small cubes and toast them lightly in the oven until they are crispy and browned. This enhances the flavor of the Kvass.

Make the Bread Mixture:

  - In a large pot, bring 10 cups of water to a boil. Remove from heat and add the toasted bread cubes. Let the mixture steep for about 4-6 hours or overnight, covered with a clean cloth.

Strain the Liquid:

  - Once the bread mixture has steeped, strain it through a fine mesh sieve or cheesecloth into a clean bowl, discarding the bread solids.

Add Sweeteners and Yeast:

  - Stir the sugar into the strained liquid until completely dissolved. Sprinkle the active dry yeast over the top and let it sit for about 15 minutes to activate.

Ferment the Kvass:

  - Transfer the mixture to a clean fermenting jar or bottle. If desired, add raisins and lemon juice for additional flavor. Cover the jar with a cloth or loose lid to allow gases to escape. Leave the jar at room temperature for 1-2 days to ferment. The length of fermentation will affect the level of sourness.

Bottle and Refrigerate:

  - Once the Kvass has reached your desired level of fermentation, strain out the raisins and transfer the liquid into clean bottles with tight-fitting lids. Refrigerate to stop the fermentation process. The Kvass can be enjoyed chilled or at room temperature.

Serve:

  - Pour the Kvass into glasses, garnish with fresh mint leaves if desired, and enjoy this refreshing, tangy beverage.
