If you have heard of Kvass or have tasted it already, you must be eager to find out what goes into making it. The unique taste of Kvass must be lingering on your taste buds. If you want to enjoy the delicious flavors of this lacto-fermented beverage, here’s all that you need to know to prepare it at home.

What is kvass

Kvass is a refreshing and effervescent lacto-fermented beverage usually made from old bread. It is full of probiotics and is easy and affordable to brew it.

Kvass is common drink in many Eastern European countries with origins in Russia, Ukraine and Lithuania. It is considered a non-alcoholic drink as the alcohol content from the fermentation is only 0.5%-1%.

To make kvass you will need sourdough starter or you can use a packet of yeast to start kvass instead. Traditionally kvass is made from rye bread, but bread from wheat or other grains can also be used. The bread should be stale but fresh bread is fine too.

What does kvass taste like

Kvass is slightly sweetish in taste with a tinge of bitterness. However, depending on how you prepare it, you can reduce or increase the sweet and bitter taste to suit your preferences.

You can let the sweet taste dominate while masking the bitterness. Alternatively, you can enjoy the mix of the sweet-bitter taste of classic Kvass.

You will also feel the traces of the taste of yeast or black bread, usually in small amounts. It bites your tongue and creates that sense of tingling. This is due to the process of carbonation and the small amount of alcohol present in it.

Kvass is a refreshing and effervescent lacto-fermented beverage usually made from old bread



  • 450 gr stale or fresh rye bread
  • 9 litres water
  • Handful of raisins
  • 4 cups sugar
  • 250 gr sourdough starter


  1. Fill the stockpot with 9 litres of water and bring to boil.
  2. Toast bread in a toaster on the darkest setting twice or directly on the racks in a preheated oven on 200°C. The darker the bread is toasted, the more flavourful the kvass will be.
  3. Cut bread in thin slices. Remove water from the heat and add the handful of raisins and toasted sliced bread. Cover it with the lid and leave it to soak for next 8 hours or overnight.
  4. Remove the toasted bread and discard it. Keep the raisins in the stockpot.
  5. Add sugar and sourdough started to the stockpot. Cover it with the lid. Leave kvass to ferment for another 8 hours and stir it as often as possible (ideally every 2 hours).
  6. Kvass should be bubbling which means it is ready to be bottled.
  7. Discard floating raisins by scooping them up with a large spoon.
  8. Gently pour kvass into plastic bottles using strainer or cheesecloth to remove any particles. Add two raisins in each bottle then close the lids.
  9. Leave the ferment in a cool place. In the next 24 hours raisins will rise to the top as kvass carbonates.
  10. Once kvass is carbonated take out the raisins and transfer bottles into refrigerator to slow continued carbonation.
  11. Serve bread kvass as cold beverage.


Equipment:3 large glass or plastic bottles, large stockpot, chopping board, knife, strainer or cheesecloth and a spoon.
