It is a living beverage that transforms simple root vegetables into a sophisticated, medicinal masterpiece that glows with a stunning magenta hue.
🥗 Ingredients
The Base
- 3-4 large Organic Red Beets (firm, unpeeled, and scrubbed clean)
- 2 quarts Filtered Water (chlorine-free to ensure healthy bacterial growth)
- 1.5 tablespoons Sea Salt (non-iodized, such as Celtic or Himalayan)
Aromatics & Flavor Enhancers
- 2 inch piece Fresh Ginger (sliced into thin rounds)
- 2 pieces Garlic Cloves (smashed)
- 1 teaspoon Black Peppercorns (whole)
- 3 pieces Allspice Berries (optional, for traditional depth)
- 2 sprigs Fresh Dill (optional)
Fermentation Starter (Optional)
- 1/4 cup Sauerkraut Juice or Liquid Whey (accelerates the process, must be unpasteurized)
👨🍳 Instructions
-
1
Thoroughly scrub the beets to remove any dirt, but do not peel them; the skins contain the beneficial wild yeasts necessary for fermentation.
-
2
Dice the beets into roughly 1-inch cubes. Avoid grating them, as too much surface area can cause the sugars to release too quickly, leading to alcohol production rather than lactic acid.
-
3
Prepare your brine by dissolving the sea salt into the filtered water. Stir vigorously until the water is clear and the salt is fully incorporated.
-
4
Place the diced beets, smashed garlic, ginger slices, peppercorns, and allspice berries into a clean 2-quart wide-mouth glass jar.
-
5
If using a starter like sauerkraut juice or whey, pour it over the beets now to give the 'good' bacteria a head start.
-
6
Pour the salt brine over the beets, ensuring they are completely submerged. Leave at least 1-2 inches of headspace at the top of the jar to allow for expansion and gas.
-
7
Seal the jar with a lid. If using a standard lid, you will need to 'burp' it daily; otherwise, use an airlock fermentation lid for a set-it-and-forget-it approach.
-
8
Place the jar in a cool, dark spot on your kitchen counter (65-75°F is ideal) and let it sit for 5 to 7 days.
-
9
Check the jar daily. If any white film (Kahm yeast) forms on the surface, simply skim it off with a clean spoon; it is harmless but can affect flavor.
-
10
Taste the liquid after day 5. It should be deep red, slightly fizzy, and have a pleasant tang. If you prefer a stronger flavor, let it ferment for up to 10 days.
-
11
Once the desired flavor profile is reached, strain the liquid into clean glass bottles using a fine-mesh sieve.
-
12
Reserve the used beet chunks! You can use them for one more 'second-run' batch (though it will be lighter) or toss them into a salad.
-
13
Transfer the bottled kvass to the refrigerator. Chilling stops the fermentation process and develops a crisp, refreshing finish.
💡 Chef's Tips
Always use filtered water, as chlorine can kill the beneficial bacteria needed for fermentation. Do not use table salt; the anti-caking agents can make your kvass cloudy and inhibit the process. If your kvass becomes syrupy or 'ropey' in texture, the temperature was likely too high; it's best to discard and start over. For a citrus twist, add a few strips of organic lemon or orange zest to the jar during the initial soak. Keep the beets submerged; if they float, use a glass fermentation weight to keep them under the brine.
🍽️ Serving Suggestions
Drink 4 ounces chilled in the morning as a probiotic digestive tonic. Use it as a vibrant, tangy base for a cold summer Borscht soup. Mix with sparkling water and a squeeze of lime for a refreshing, savory mocktail. Use it as a pickling liquid for hard-boiled eggs to give them a stunning purple ring. Whisk a splash into olive oil and Dijon mustard for a probiotic-rich salad dressing.
