❤️ Beet Kvass With Honey for Natural Fizz

Beet kvass is a beautiful ruby-red fermented drink made with beets, water, and salt. It has a pleasantly earthy, tangy flavor, and with a little honey added during bottling, you can encourage a natural second fermentation that creates gentle carbonation.

The result is a sparkling, slightly sweet, pleasantly tart drink that’s especially beautiful served cold over ice.

Important: Adding honey at bottling gives the remaining microorganisms a new source of sugar, which can create carbon dioxide. That also means pressure can build quickly. Use only bottles designed for carbonated beverages, leave headspace, refrigerate once adequately carbonated, and don’t use ordinary glass jars or bottles that aren’t pressure-rated.

🥤 Beet Kvass Recipe

Ingredients

For the First Fermentation

2–3 medium fresh beets
4 cups non-chlorinated water
1½ tablespoons non-iodized salt, approximately 27 g
2 cloves garlic, optional
1 small piece fresh ginger, optional
1 teaspoon caraway seeds, optional

For Bottling

1–2 teaspoons raw or regular honey per 16-ounce (475 ml) bottle
Fermented beet kvass, strained
Optional: a small squeeze of lemon juice

Equipment

1-quart (1-liter) fermentation jar
Fermentation weight, if available
Clean cloth or fermentation lid
Fine-mesh strainer
Pressure-rated bottles suitable for carbonation
Funnel
Refrigerator

🥣 Step 1: Prepare the Beets

Wash the beets thoroughly.

Trim away the tops and roots and peel them if desired. Cut the beets into roughly ½-inch cubes.

There’s no need to make the pieces perfectly uniform.

Place the beet cubes into your clean fermentation jar.

If you’re using garlic, ginger, or caraway, add them now.

🧂 Step 2: Make the Salt Brine

Dissolve approximately 27 grams of non-iodized salt in 4 cups (946 ml) of water.

A kitchen scale is the most reliable way to measure salt for fermentation because different types of salt have different volumes by weight.

Pour the brine over the beets.

The vegetables should remain completely submerged.

If necessary, use a fermentation weight to keep the beet pieces underneath the liquid.

Why the salt?

Salt helps create an environment favorable to lactic-acid fermentation while discouraging many unwanted microorganisms.

🫙 Step 3: Begin Fermentation

Cover the jar with a fermentation lid or another appropriate setup that allows fermentation gases to escape.

Keep the jar at room temperature, away from direct sunlight.

The fermentation time can vary with temperature and your preferred flavor, but about 3–5 days is a reasonable starting point.

You may notice:

Small bubbles
A pleasant sour aroma
A slightly tangy taste
The liquid becoming increasingly vibrant red

Taste a little each day once fermentation is underway.

When the kvass has developed a pleasantly sour flavor that you enjoy, it’s ready for the next step.

🧊 Step 4: Strain the Kvass

Pour the fermented liquid through a clean fine-mesh strainer.

Remove the beet pieces and other solids.

The finished liquid should be a gorgeous deep ruby color.

At this point, you have beet kvass.

But we’re going one step further.

We’re going to add a little honey during bottling to encourage natural carbonation.

🍯 Step 5: Add Honey for Carbonation

Pour the strained kvass into a clean measuring jug.

For carbonation, add approximately:

1–2 teaspoons honey per 16-ounce (475 ml) bottle.

Start toward the lower end if you’re new to bottle conditioning.

The honey provides fermentable sugar. Microorganisms remaining in the kvass can consume some of that sugar and produce carbon dioxide, creating the fizz.

Don’t add a large amount of honey thinking it will simply make the drink sweeter.

More honey can mean more fermentation and more pressure.

🍾 Step 6: Bottle Carefully

Using a clean funnel, transfer the kvass into pressure-rated bottles specifically designed for carbonated beverages.

Leave the amount of headspace recommended by the bottle manufacturer.

Seal the bottles.

Don’t use ordinary decorative bottles, thin glass bottles, mason jars, or other containers that aren’t designed to withstand carbonation pressure.

⏰ Step 7: Let It Carbonate

Leave the sealed bottles at room temperature for a short period while carbonation develops.

The exact timing depends on the temperature, amount of honey, microbial activity, and bottle size, so don’t rely on a fixed number of hours as a guarantee.

Check the bottles regularly.

Once the kvass has reached the carbonation level you want, move the bottles to the refrigerator.

Cold temperatures slow fermentation considerably and help preserve the carbonation.

❄️ Step 8: Refrigerate Before Drinking

Chilling the bottles is important.

The colder liquid also holds carbon dioxide more effectively, so your kvass will generally pour more pleasantly once thoroughly chilled.

When opening a bottle for the first time, do so slowly and over a sink, especially if you’re unsure how much pressure has developed.

If it appears excessively pressurized, don’t shake it or point the opening toward anyone.

🍋 Optional Flavor Ideas

The earthy flavor of beet kvass pairs beautifully with other ingredients.

Try adding one of these during the initial fermentation:

Ginger Beet Kvass

Add several slices of fresh ginger.

The ginger gives the earthy beets a bright, spicy note.

Garlic Beet Kvass

Add one or two cloves of garlic for a more savory version.

Lemon-Ginger Beet Kvass

Add ginger during fermentation and a small amount of fresh lemon juice after straining and before bottling.

Beet & Caraway

A small amount of caraway gives the kvass a distinctive savory flavor.

❤️ What Does Beet Kvass Taste Like?

If you’ve never tried it, don’t expect it to taste like beet juice.

Traditional beet kvass is usually:

Tangy
Earthy
Slightly salty
Savory
Lightly fermented

Adding honey during bottling can give it a gentle sweetness and a naturally fizzy finish.

The combination of earthy beet + tangy fermentation + a little honey + carbonation makes a surprisingly interesting drink.

🫙 What About the Fermented Beets?

Don’t automatically throw them away!

The fermented beet pieces can sometimes be incorporated into meals, provided they remain wholesome and have been handled and stored safely.

Try chopping them into:

Salads
Grain bowls
Sandwiches
Vegetable dishes

Or simply enjoy a small amount alongside a meal.

⚠️ Important Fermentation Safety

Because this recipe involves fermentation and sealed bottles, safety deserves special attention.

Use clean equipment

Wash jars, utensils, weights, and bottles thoroughly before beginning.

Keep the vegetables submerged

Vegetables exposed above the brine are more likely to develop mold or other undesirable growth.

Don’t use visibly spoiled fermentation

If you see fuzzy mold, unusual colors, or anything that looks genuinely rotten or contaminated, discard the batch rather than trying to save it.

Don’t over-sugar the bottles

Honey is being used here as a fermentation fuel, not simply as a sweetener.

Too much fermentable sugar can result in excessive carbonation and dangerous pressure.

Use proper bottles

This is perhaps the most important point.

Use bottles specifically manufactured for carbonated drinks.

Don’t improvise with ordinary glass containers.

Refrigerate when carbonated

Once you’ve reached the carbonation you want, move the bottles into the refrigerator to slow fermentation.

🍯 Why Add Honey at Bottling?

This is essentially a small second fermentation.

During the first fermentation, naturally occurring microorganisms consume some of the available carbohydrates and produce acids and other fermentation products.

After straining, adding a measured amount of honey gives those microorganisms another source of fermentable sugar.

Inside a sealed carbonation bottle, the carbon dioxide produced during this process becomes dissolved in the liquid.

That’s where the bubbles come from.

So the honey isn’t simply making the kvass taste sweeter.

It’s helping create the fizz.
