Fermented Beverages Beyond Kombucha: 9 Probiotic Drinks You Should Try

Kombucha has become the gateway fermented beverage for millions of health-conscious consumers. But if kombucha is all you know, you’re missing an entire world of probiotic drinks with different flavors, health benefits, and cultural traditions. From Russian kvass made with bread to Mexican tepache from pineapple peels, fermented beverages have developed independently across every culture with access to sugar, water, and time.

Each fermented beverage offers unique advantages. Water kefir produces more probiotic diversity than kombucha with less caffeine. Kvass provides an earthy, savory alternative for those who find kombucha too sweet. Tepache transforms kitchen scraps into a tropical probiotic treat. And milk kefir delivers more beneficial bacteria per serving than almost any other food.

This guide explores nine fermented beverages beyond kombucha, explaining their origins, health benefits, flavor profiles, and how to make them at home. Whether you’re looking for dairy-free options, faster fermentation times, or simply new flavors, you’ll find probiotic drinks that expand your fermentation repertoire.

1. Water Kefir: The Versatile Dairy-Free Probiotic

What is Water Kefir?

Water kefir is a fermented beverage made by culturing sugar water with water kefir grains – gelatinous clusters of bacteria and yeast that look like small, translucent crystals. Unlike milk kefir grains, water kefir grains don’t require dairy, making this an excellent probiotic option for vegans and those avoiding lactose.

The fermentation produces a mildly sweet, slightly tangy, effervescent drink similar to a natural soda. Water kefir serves as an excellent base for flavoring – add fruit juice, ginger, herbs, or citrus during a second fermentation to create endless flavor variations.

Probiotic Benefits

Water kefir contains numerous strains of beneficial bacteria including Lactobacillus, Leuconostoc, and Acetobacter species, plus beneficial yeasts like Saccharomyces. The probiotic diversity rivals or exceeds kombucha, and the absence of caffeine makes it appropriate for children and those sensitive to stimulants.

How to Make Water Kefir

Ingredients:

• 1/4 cup water kefir grains
• 1/4 cup organic cane sugar
• 4 cups filtered water (chlorine-free)
• Pinch of unrefined salt (provides minerals for grain health)

Instructions:

1. Dissolve sugar in warm water, then cool to room temperature
2. Add water kefir grains and salt to a quart jar
3. Cover with cloth and rubber band (needs air flow)
4. Ferment 24-48 hours at room temperature
5. Strain out grains (reuse for next batch)
6. Optional: Second ferment with fruit for 24-48 hours in sealed bottles for carbonation

Fermentation time: 24-48 hours primary, plus 24-48 hours secondary if carbonating

Difficulty: Easy – very forgiving process

2. Milk Kefir: The Probiotic Powerhouse

What is Milk Kefir?

Milk kefir is fermented milk, similar to drinkable yogurt but with dramatically more probiotic diversity. Kefir grains – cauliflower-like clusters of bacteria and yeast – ferment the milk’s lactose into lactic acid, creating a tangy, slightly effervescent beverage with a thin, pourable consistency.

Originating in the Caucasus Mountains, kefir has been consumed for over 2,000 years. The word “kefir” comes from the Turkish word for “feeling good,” reflecting its traditional reputation for health benefits.

Probiotic Benefits

Milk kefir is arguably the most probiotic-rich food available. A single serving can contain up to 61 different strains of bacteria and yeasts – compared to yogurt’s typical 2-7 strains or kombucha’s 10-15. These include Lactobacillus kefiri, found exclusively in kefir and shown to inhibit harmful bacteria like Salmonella and E. coli.

The fermentation process breaks down most lactose, making kefir tolerable for many people with lactose intolerance. The proteins are also partially digested, improving digestibility.

How to Make Milk Kefir

Ingredients:

• 1-2 tablespoons milk kefir grains
• 2 cups whole milk (pasteurized is fine, avoid ultra-pasteurized)

Instructions:

1. Place kefir grains in a quart jar
2. Add room-temperature milk
3. Cover with cloth and rubber band
4. Ferment 12-24 hours at room temperature until thickened
5. Strain out grains (reuse for next batch)
6. Refrigerate finished kefir

Fermentation time: 12-24 hours

Difficulty: Easy – hard to fail if using active grains

3. Kvass: The Russian Bread Beverage

What is Kvass?

Kvass is a traditional Slavic fermented beverage made from rye bread (bread kvass) or beets (beet kvass). The bread version tastes malty, slightly sour, and earthy – like a very mild beer but with minimal alcohol (typically 0.5-1%). Beet kvass is earthier, with the deep red color and subtle sweetness of beets.

In Russia and Eastern Europe, kvass has been consumed daily for centuries. Street vendors traditionally sold it from large tanks, and many families maintain generations-old recipes. It’s sometimes called “Russian cola” due to its everyday popularity.

Health Benefits

Beet kvass is particularly valued for liver support and blood purification in traditional medicine. Modern research confirms beets’ beneficial effects on blood pressure, athletic performance, and detoxification pathways. Fermenting beets makes these benefits more bioavailable while adding probiotic bacteria.

Bread kvass provides B vitamins from the yeast fermentation and the probiotics from lacto-fermentation. It’s a traditional remedy for digestive complaints and hangover relief in Russia.

How to Make Beet Kvass

Ingredients:

• 2-3 medium beets, peeled and roughly chopped (not grated)
• 1 tablespoon sea salt
• Filtered water to fill jar
• Optional: 2 tablespoons sauerkraut juice (as starter)

Instructions:

1. Place chopped beets in a half-gallon jar
2. Add salt and optional starter
3. Fill with filtered water, leaving 1-inch headspace
4. Cover with cloth and rubber band
5. Ferment 3-7 days at room temperature until pleasantly sour
6. Strain and refrigerate (use beets in salads)

Fermentation time: 3-7 days

Difficulty: Easy – very forgiving, hard to fail

4. Tepache: Mexican Pineapple Probiotic

What is Tepache?

Tepache is a traditional Mexican fermented beverage made primarily from pineapple rinds and cores – the parts usually discarded. It’s lightly fermented, mildly alcoholic (1-2%), and tastes like sparkling pineapple juice with spice notes. Street vendors throughout Mexico serve it with tajin (chili-lime seasoning) and as a mixer for cocktails.

Tepache represents the zero-waste wisdom of traditional fermentation. Parts of the pineapple too tough to eat directly transform into a refreshing probiotic drink, extending the value of each fruit.

Health Benefits

Pineapple contains bromelain, an enzyme that aids protein digestion and reduces inflammation. Fermentation increases bromelain bioavailability while adding beneficial bacteria. The vitamin C from pineapple also remains largely intact.

Tepache’s quick fermentation means lower alcohol than beverages like wine or beer, making it a refreshing alternative to both soda and alcoholic drinks.

How to Make Tepache

Ingredients:

• Rind and core of 1 ripe pineapple
• 1 cup piloncillo or brown sugar
• 1 cinnamon stick
• 4-5 whole cloves
• 8 cups water

Instructions:

1. Combine all ingredients in a large jar or pitcher
2. Cover with cloth and rubber band
3. Ferment 2-3 days at room temperature, stirring once daily
4. When bubbling and pleasantly sour-sweet, strain and refrigerate
5. Serve cold with ice, optional chili-lime seasoning

Fermentation time: 2-3 days (one of the fastest ferments!)

Difficulty: Very easy – great beginner project

5. Jun Tea: The Champagne of Kombucha

What is Jun Tea?

Jun tea is sometimes called “the champagne of kombucha” for its lighter, more effervescent character. Made with green tea and raw honey instead of black tea and sugar, jun produces a more delicate, floral flavor profile than traditional kombucha. The honey contributes subtle sweetness and complexity.

Jun’s origins are debated – some claim ancient Tibetan monasteries, others suggest it’s a modern adaptation. Regardless of history, jun has developed its own culture (literally – the SCOBY) that’s distinct from kombucha and specifically adapted to honey fermentation.

Probiotic Benefits

Jun contains similar probiotic strains to kombucha but with added benefits from raw honey’s natural antimicrobial and prebiotic properties. Some practitioners find jun easier to digest than kombucha, possibly due to the gentler acids produced from green tea fermentation.

How to Make Jun Tea

Ingredients:

• 1 jun SCOBY with 1 cup starter tea (not a kombucha SCOBY)
• 1 gallon filtered water
• 4-5 bags green tea (or 4 tablespoons loose leaf)
• 1 cup raw honey

Instructions:

1. Brew green tea in hot (not boiling) water for 3-5 minutes
2. Remove tea and add honey while warm (not hot – protect enzymes)
3. Cool to room temperature
4. Add jun SCOBY and starter tea
5. Cover with cloth, ferment 5-7 days
6. Second ferment with fruits/herbs if desired

Important: Use a jun-specific SCOBY. Kombucha SCOBYs are adapted to cane sugar and may not thrive with honey.

Fermentation time: 5-7 days primary (faster than kombucha)

Difficulty: Moderate – requires specific culture and temperature attention

6. Ginger Beer: Spicy Probiotic Soda

What is Fermented Ginger Beer?

True fermented ginger beer (not the commercial soda variety) is a naturally carbonated beverage made by fermenting fresh ginger with sugar and water. The result is a spicy, effervescent drink with actual ginger heat and complex flavor – far superior to artificial ginger ales.

Fermented ginger beer requires a “ginger bug” – a starter culture created by feeding grated ginger and sugar with water over several days. Once established, this bug can ferment batch after batch of ginger beer indefinitely.

Health Benefits

Ginger provides well-documented digestive benefits: it reduces nausea, stimulates digestive enzymes, and has anti-inflammatory properties. Fermented ginger beer combines these benefits with probiotics from the fermentation. It’s traditionally used for motion sickness, morning sickness, and general digestive upset.

How to Make a Ginger Bug

Ingredients:

• 2 tablespoons grated fresh ginger (with skin)
• 2 tablespoons sugar
• 2 cups filtered water

Instructions:

1. Combine ingredients in a quart jar
2. Cover with cloth, stir daily
3. Each day for 5-7 days, add another tablespoon each of ginger and sugar
4. When actively bubbling, your ginger bug is ready to use
5. Maintain by feeding weekly if not using regularly

How to Make Ginger Beer

Ingredients:

• 1/4 cup strained ginger bug liquid
• 1/4 cup grated fresh ginger
• 1/2 cup sugar
• Juice of 2 lemons
• 4 cups water

Instructions:

1. Simmer ginger in 2 cups water for 15 minutes to make ginger “tea”
2. Add sugar and stir to dissolve
3. Cool to room temperature, add remaining water, lemon juice, and ginger bug
4. Pour into flip-top bottles, leaving headspace
5. Ferment 2-3 days, burping bottles daily
6. Refrigerate when carbonated

Fermentation time: 5-7 days for bug, then 2-3 days per batch

Difficulty: Easy-moderate – forgiving process once bug is established

7. Switchel: The Original Energy Drink

What is Switchel?

Switchel (also called haymaker’s punch) is a traditional American beverage made from apple cider vinegar, ginger, and sweetener mixed with water. Originally served to farmers during harvest to prevent heat exhaustion, it’s experiencing a modern revival as a natural sports drink.

While traditional switchel isn’t fermented beyond the vinegar, a fermented version can be made by allowing the mixture to develop wild fermentation, creating additional probiotics and natural carbonation.

Health Benefits

Apple cider vinegar with “the mother” contains acetic acid bacteria and may help with blood sugar regulation, appetite control, and digestive health. Ginger adds anti-inflammatory and digestive benefits. The combination of acids, minerals, and natural sugars creates an effective rehydration drink.

How to Make Fermented Switchel

Ingredients:

• 1/4 cup apple cider vinegar with “the mother”
• 2 tablespoons fresh grated ginger (or 1 tablespoon ginger juice)
• 2 tablespoons maple syrup or honey
• 4 cups filtered water
• Pinch of sea salt

For fermented version, add:

• 2 tablespoons ginger bug liquid OR
• 2 tablespoons water kefir

Instructions:

1. Combine all ingredients and stir well
2. For unfermented version: refrigerate and enjoy immediately
3. For fermented version: bottle in flip-top bottles, ferment 1-3 days at room temperature until carbonated, then refrigerate

Fermentation time: 0-3 days (can be enjoyed immediately or fermented)

Difficulty: Very easy – essentially just mixing ingredients

8. Rejuvelac: The Fermented Grain Water

What is Rejuvelac?

Rejuvelac is a fermented drink made from sprouted grains – typically wheat berries, quinoa, or rye. The grains are sprouted, then soaked in water to ferment, creating a tangy, lemony beverage rich in enzymes and beneficial bacteria.

Popularized by raw food advocate Ann Wigmore in the 1960s, rejuvelac is used both as a probiotic drink and as a starter culture for making raw vegan cheeses and other fermented foods.

Health Benefits

Rejuvelac is enzyme-rich, containing amylase, protease, and other digestive enzymes that may improve nutrient absorption. The fermentation process creates B vitamins and beneficial Lactobacillus bacteria. For those avoiding dairy, rejuvelac provides a grain-based probiotic option.

How to Make Rejuvelac

Ingredients:

• 1 cup wheat berries, quinoa, or rye berries
• Filtered water for sprouting and fermenting

Instructions:

1. Soak grains in water overnight, then drain
2. Sprout grains 2-3 days, rinsing twice daily, until small tails appear
3. Place sprouted grains in a jar with 4 cups filtered water
4. Cover with cloth, ferment 1-3 days at room temperature
5. When cloudy and pleasantly tangy (like lemon water), strain and refrigerate
6. Can do second batch with same grains (will ferment faster)

Fermentation time: 2-3 days sprouting, then 1-3 days fermenting

Difficulty: Easy – but requires patience for sprouting phase

9. Amazake: The Sweet Japanese Rice Drink

What is Amazake?

Amazake (sweet sake) is a traditional Japanese fermented rice beverage made with koji – the same Aspergillus oryzae mold used to make sake, miso, and soy sauce. Unlike sake, amazake is either non-alcoholic or very low in alcohol, and tastes naturally sweet despite no added sugar.

The koji enzymes break down rice starches into sugars during fermentation, creating natural sweetness. The texture is thick and creamy, often served warm as a comforting winter drink or chilled as a summer refresher.

Health Benefits

Amazake is sometimes called “drinkable IV” in Japan because its nutritional profile resembles intravenous nutrient solutions. It’s rich in B vitamins, amino acids, and easily digestible carbohydrates. Traditional Japanese medicine uses amazake to support digestive health, provide energy, and aid recovery from illness.

How to Make Amazake

Ingredients:

• 1 cup cooked short-grain white rice (cooled)
• 1 cup rice koji (available at Japanese grocers or online)
• 2-3 cups water

Instructions:

1. Combine cooled rice, koji, and water in a pot or rice cooker
2. Keep at 130-140°F (55-60°C) for 8-12 hours. Use a yogurt maker, instant pot “yogurt” setting, or oven with light on
3. The mixture should become sweet and fragrant
4. Blend for smooth texture or leave chunky
5. Refrigerate and consume within 1-2 weeks
6. Serve warm, cold, or blended into smoothies

Fermentation time: 8-12 hours at warm temperature

Difficulty: Moderate – requires temperature control

Frequently Asked Questions

Which fermented beverage has the most probiotics?

Milk kefir contains the highest probiotic diversity, with up to 61 different bacterial and yeast strains per serving. Water kefir is the best dairy-free option for probiotic diversity, typically containing 10-20+ strains. Kombucha usually contains 10-15 strains.

Are these beverages safe for children?

Water kefir, milk kefir, kvass, tepache, and amazake are generally safe for children in appropriate portions. Jun and kombucha contain caffeine and should be limited or avoided for young children. Ginger beer and tepache contain trace alcohol (1-2%) and should be served to children in small amounts if at all. Always introduce new fermented foods gradually.

How do I know if my fermented beverage has gone bad?

Signs of spoilage include visible mold (fuzzy growth on surface), extremely unpleasant odors (beyond normal fermented sourness), slimy texture (except for naturally viscous beverages like amazake), or off colors. When in doubt, discard and start fresh. Properly fermented beverages should smell pleasantly tangy, not putrid.

Can I use the same SCOBY or grains interchangeably?

No – different cultures are adapted to different environments. Kombucha SCOBYs won’t thrive in honey (use jun SCOBYs). Milk kefir grains will die in water (use water kefir grains). Ginger bugs are distinct from kefir grains. Each culture is a unique microbial ecosystem suited to its specific fermentation environment.

Which fermented beverage is best for weight loss?

Low-sugar options like kvass, unsweetened kombucha, and diluted switchel contain minimal calories while providing probiotics linked to healthy weight management. Avoid highly sweetened second fermentations. Milk kefir provides protein that supports satiety. No fermented beverage is a magic weight loss solution, but they’re healthier alternatives to soda and sugary drinks.

Food Safety Note

When fermenting at home, always use clean equipment, filtered water (chlorine inhibits fermentation), and fresh ingredients. Most fermented beverages should be refrigerated after reaching desired fermentation to slow ongoing fermentation. Be cautious with carbonated beverages – always burp bottles during fermentation to prevent explosions. If immunocompromised or pregnant, consult healthcare providers before consuming homemade fermented beverages.
