What is Beet Kvass?
Beet Kvass is a traditional Eastern European drink made by fermenting raw beets in salt water. This Russian probiotic drink is tangy, slightly earthy, and an acquired taste for many. Often referred to as the “blood of the earth,” Beet Kvass is loaded with good bacteria that support digestion and overall health.
How Long Does It Take to Ferment?
Typically, Beet Kvass takes about 3-4 days to ferment at room temperature in a large glass jar. The time can vary depending on the temperature and the size of the beet pieces. The longer it ferments, the stronger and more tangy the flavor becomes.
Can I Use Tap Water?
It’s best to use filtered water or spring water for making Beet Kvass. Regular tap water often contains chlorine and other chemicals that can interfere with the fermentation of beet kvass. If you must use tap water, let it sit for 24 hours to allow the chlorine to evaporate, or use a reverse osmosis filter.
Is Beet Kvass Alcoholic?
Beet Kvass contains a minimal amount of alcohol, similar to other lacto-fermented drinks like ginger ale or kombucha. The alcohol content is very low, making it safe for most people, including those who are sensitive to alcohol.
How Do I Know If My Kvass Has Gone Bad?
If your kvass has an off smell, a slimy texture, or visible mold that isn’t Kahm yeast, it’s best to discard it. Proper sanitation of your jars and utensils is the only thing that can prevent contamination. If in doubt, start a second batch to ensure safety.

Tips On How To Make Fermented Beet Kvass
- Use Organic Beets: Raw beets are the star of this recipe. If possible, buy organic at your local health food store or farmers market to avoid pesticides. If they’re organic, you can leave the skin on, which adds extra nutrients and flavor.
- Choose the Right Salt: Opt for high-quality sea salt, like Celtic Sea Salt or Pink Himalayan Salt. Using less salt is key to a balanced flavor while still promoting good fermentation.
- Avoid Metal Utensils: Use wooden or plastic utensils when working with your kvass. Metal can react with the salt, affecting the fermentation of beet kvass.
- Keep it at Room Temperature: Store your kvass at room temperature, away from direct sunlight, in a large jar or fermenting jar. The ideal environment helps the beet kvass ferments properly.
- Skim Off Kahm Yeast: If you notice a white film on top of the liquid, it’s likely Kahm yeast. Skim it off regularly to prevent it from affecting the taste.
