Salty beet kvass has a salty, sweet and sour flavour that is surprisingly refreshing when chilled before serving. It reminds me of a clear Polish-style borscht, and makes an excellent mid-afternoon snack.
What is beet kvass?
Kvass is Russian word for a simple fermented sparkling beverage. Beer likely originated from a sourdough bread kvass. Brad’s Doukhobor cookbooks always have a recipe for cucumber kvass. And beet kvass is a simple beverage made from fermented beets. It can be made salty or sweet, depending on whether you use salt or honey to control the fermentation.
Though I occasionally make sweet beet kvass, and I usually have a jar of immune boosting beet kvass in my fridge all winter long, salty beet kvass is my favourite. It tastes like a mix between a chilled soup and a salty beverage. I particularly like having a glass as a delicious and satisfying mid-afternoon snack.
Salty beet kvass is also a good starter for other ferments. I personally like using kvass to make purple fermented eggs.

- Category: Beverages
- Method: Fermented
- Cuisine: Polish
Ingredients
- 1 cup beets washed, and diced into cubes (about 2–4 whole beets)
- 1/4 cup of starter culture (see notes)
- 1/2 tbsp salt (non-iodized)
- 2 1/2 cups filtered water, to cover (chlorine free)
Instructions
- Sterilize a quart-sized jar and fill it with the beet cubes.
- Add the culture.
- Dissolve the salt in 1/2 cup of water, pour over the beets. Add the remaining water to cover the beets.
- Use a weight to keep the beets submerged, top with a lid, and allow to ferment somewhere cool for 1 week.
- Store in the fridge and consume within 1 month.
Notes
- Beets don’t require a starter, however, I usually use whey. You could also use sauerkraut juice or a purchased starter (affiliate link.)
- You can flavour the kvass by adding fresh dill and garlic (for a borscht flavour). Brad enjoys adding a stick of celery and drinking it like an vegetable juice!

I add a bit of ginger bug to mine to get things started.
What a good idea!
