Beet kvass: The easiest, quickest fermented drink you can make

I just made this for the first time, and I want to share how easy it is! I found it full of umami flavor – earthy, salty, and tangy.

Everyone is learning how good fermented foods are — tangy, tasty, and a way to get probiotics into your gut without expensive supplements that may or may not actually get those probiotics to just the right place in your digestive tract.

Beet kvass is something you can easily make at home that is ready to consume in as little as two days! And…it’s a time-tested traditional food known to have profound health-giving qualities.

beet kvass, The Well

My First Batch

Since I wasn’t sure if I’d even like it enough to make it again, my first batch was small. I put one golden beet, washed but unpeeled and cut into half-inch cubes, into a quart jar, added 1 tablespoon of salt, a teaspoon of sauerkraut juice (from the refrigerated live kind, not canned cooked kraut), and filled the jar with filtered water, leaving an inch of space at the top. Swished it around a bit before clamping the jar tightly shut.

I left it out on the counter and let it ferment for two days. I opened the jar daily to release gases. No scum formed on the top, but if it had, this is when I’d scoop it off and discard it.

I recommend sniffing and tasting it each day, because with experience, you’ll know when it’s fermented to just the right degree for your tastebuds. It’s warm in Austin, Texas, in early June, and warmth speeds fermentation. It will take longer if your kitchen is cooler. A week is more typical.

After two days, the brine had turned golden at the bottom of the jar. I stirred it to mix and then drank a little to test.

Wow. Yum! I really liked the taste! It had a mineral earthiness from the beet, saltiness, and a sour tanginess from the fermentation and the kraut juice. I drank half a cup and then another! It was as if my body really needed these nutrients.

I put the jar, beets and all, into the refrigerator to stop the fermentation and preserve the goodness.

Making Another Batch

Kvass (sometimes spelled kvas), like sourdough and kombucha, keeps on giving. When you’ve drunk most of the brine, leave the beets and a bit of the liquid in the jar to act as a starter, refill the jar with filtered water, and add salt. Let it sit on the counter for a few days again. Smell and taste to see when it’s done.

Always save a bit of the brine for starter, but if you don’t have any, you can use sauerkraut juice, whey (not the body-building powder but the byproduct of making cheese or Greek yogurt), or a commercial starter. After two or three batches, start over with fresh beets. Use the discarded beets in soups or juices or compost them.

I can’t wait to try it with red beets for the beautiful color! I’ll make a larger batch next time since I like the flavor so much.

Update: It’s now October 2016, and I’ve made beet kvass numerous times, keeping it on hand always. Use red or golden beets, your choice. Haven’t tried the striped Chioggia beets yet, but I will.

I’ve shared my kvass with someone who loves beets but thought it was too salty, so I’ve experimented with using less salt.

Right now I’m liking this recipe per half gallon jar:

2 medium diced beets, unpeeled
1 teaspoon Real salt
1 tablespoon thinly sliced fresh ginger or 1 tablespoon whole cloves
1/2 to 1/4 cup kvass from previous batch (or sauerkraut juice, whey, or starter)
filtered water

Cover the jar with a lid. Check daily, smelling, tasting, and removing any scum from the top. Refrigerate when it tastes “done” to your taste. Reuse beets 2 or 3 times before starting over.

Medicinal and Nutritional Qualities

According to the cookbook Nourishing Traditions:

This drink is valuable for its medicinal qualities and as a digestive aid. Beets are just loaded with nutrients. One 4-ounce glass, morning and night is an excellent blood tonic, promotes regularity, aids digestion, alkalizes the blood, cleanses the liver and is a good treatment for kidney stones and other ailments.

Folk medicine values beets and beet kvass for their liver cleansing properties and beet kvass is widely used in cancer therapy in Europe. Anecdotal reports indicate that beet kvass is an excellent therapy for chronic fatigue, chemical sensitivities, allergies and digestive problems.

According to the Weston A. Price Foundation, kvass was historically known to protect against infectious diseases such as cholera.

Beets contain the following vitamins and minerals: folate, manganese, potassium, magnesium, phosphorus, Vitamin C, iron, and Vitamin B6. They also contain betalains, phytonutrients with anti-inflammatory, anti-oxidant, and detoxifying qualities, and are the highest known non-grain source of betaine for cardiovascular health and reducing inflammation.

Origins

According to Wikipedia, kvass (which simply means “leavened”) is a drink made of fermented bread. It is popular in Russia and has been a common drink in Eastern Europe since at least the Middle Ages. Bakers make it from stale sourdough rye bread, itself a fermented food.

From what I could tell, beet kvass is common in Ukraine and probably comes from there. WAPF describes beet kvass as more medicinal than epicurean but notes that in Ukraine, beet kvass is added to borscht.

Sources say kvass can be flavored with currants, raspberries, lemons, apples, pears, cherries, bilberries, lingonberries, herbs, and birch sap. It is unclear whether these are used as flavorings for bread kvass, or if they are additions to beet kvass, or both.

I’ve experimented with adding ginger, cinnamon sticks, cloves, and allspice to add spiciness to the mix with good results.

      • In my next batch, I filled the jar 1/3 full of red beets and used the full 1 Tablespoon of salt. This made a stronger brew because the added salt draws out more beet goodness. When I drink it, I often add my fiber mix (ground flax seeds, chia, and psyllium) to make a really tasty drink. It’s interesting that now I don’t experience it as being too salty, perhaps because I dilute it when I drink it. I used the beets from my first batch in a salad and it was OK. The beets had lost a lot of their flavor to the drink. Still healthy, though. I just re-read this blog and see that I can make another batch by re-using the beets. You don’t say–should I add another TB of salt with the added water? I also added a bit of whey to the mix in addition to the sauerkraut juice. It didn’t change the taste, but probably added a few additional types of bacteria.

        Thanks so much for sharing this! It’s now part of my daily regimen.

      • Peggy, how much do you dilute your kvass? I would add slightly less than a TB of salt to the second batch since you’re adding a bit of fermented kvass along with the beets from the first batch. I added ginger shavings to my most recent batch: delicious!

  1. I didn’t add any salt to the second batch because you didn’t mention it. How much I dilute it depends on how strong I’ve made it. I like it full strength, too. Just tasted the second batch that I put out yesterday. It tasted like it needs salt, so I added 1 tsp. Even after 1 day, it tastes great. And you ferment the ginger along with it? Even more health benefits! Just added some to a glass of it now and it tastes great.
