Kombucha has become one of the most talked-about wellness drinks in the U.S., often found in everything from farmers’ markets to national grocery chains. But as more people swap out sodas and energy drinks for this fizzy, fermented tea, one question keeps coming up: Does kombucha have caffeine?
The answer isn’t entirely straightforward. Kombucha is made from tea—usually black or green—which naturally contains caffeine. But fermentation changes things. In this article, we’ll break down how much caffeine kombucha actually has, how it compares to coffee and other drinks, and what you should consider in 2025 as kombucha continues to trend in the U.S.
What Is Kombucha, Exactly?
Kombucha is a fermented tea beverage made by combining brewed tea with sugar and a SCOBY (symbiotic culture of bacteria and yeast). Over time, the microbes in the SCOBY consume the sugar and caffeine, producing a tangy, slightly effervescent drink that’s rich in probiotics, acids, and sometimes trace amounts of alcohol.
Kombucha has been consumed for centuries, but its popularity in the United States has skyrocketed in the past decade. According to market analysts, the U.S. kombucha market is projected to reach over $8 billion by 2027, fueled by a growing demand for natural gut-health solutions.
Does Kombucha Have Caffeine?
Short answer: Yes, kombucha contains caffeine—but in relatively small amounts.
Since kombucha starts with tea (usually black or green), it naturally contains some caffeine. However, the fermentation process reduces caffeine levels. Exactly how much remains depends on a few factors:
- Type of tea used (black tea has more caffeine than green)
- Fermentation time (longer fermentation = lower caffeine)
- Dilution (some kombuchas are cut with fruit juices or herbal teas)
Typical Caffeine Content in Kombucha
Here’s a general comparison of caffeine levels:
| Beverage | Caffeine (per 8 oz) |
| Black tea (brewed) | 40–70 mg |
| Green tea (brewed) | 20–45 mg |
| Kombucha (avg store-bought) | 10–25 mg |
| Decaf coffee | 2–5 mg |
| Regular coffee | 80–100 mg |
| Soda (cola) | 20–40 mg |
In 2025, many leading kombucha brands in the U.S. list caffeine content directly on their labels to accommodate consumer preferences and FDA guidance for transparency.
What Influences the Caffeine Level in Kombucha?
Several variables can change how much caffeine ends up in your kombucha:
1. Type of Tea
Black tea-based kombucha typically has higher caffeine levels than green or white tea versions. Herbal teas like hibiscus or rooibos, when used alone, result in caffeine-free kombucha.
2. Length of Fermentation
The longer the brew ferments, the more caffeine the SCOBY consumes. Home-brewed kombucha that ferments for 14+ days may contain less caffeine than store-bought varieties fermented quickly for flavor consistency.
3. Brand and Recipe
Some commercial brands add extra tea or infuse their kombucha with green coffee bean extract or yerba mate for an energy boost—meaning added caffeine. Others dilute their final product with fruit juices or adaptogens like ashwagandha.
To know what you’re drinking, always check the label—or visit the brand’s website for a caffeine disclosure.
Does Caffeine in Kombucha Affect You Like Coffee or Soda?
For most people, the low-to-moderate caffeine content in kombucha isn’t enough to cause jitters, insomnia, or a caffeine crash. However, sensitivity varies. If you’re caffeine-sensitive, even a small amount (10–20 mg) can make a difference.
Consider these scenarios:
- Morning kombucha can give a subtle lift without the crash.
- Afternoon sipping may still be energizing without disrupting your sleep.
- Evening consumption is better with caffeine-free kombucha options.
Can You Get Caffeine-Free Kombucha?
Yes! Caffeine-free kombucha is available and growing in popularity, especially for kids, pregnant women, and people trying to reduce stimulant intake.
Look for these labels:
- “Herbal kombucha”
- “Caffeine-free”
- “Naturally decaffeinated”
Brands like Health-Ade and Brew Dr. now offer caffeine-free options using herbal teas such as chamomile or hibiscus.
Kombucha Trends in the U.S. (2024–2025)
As of 2025, kombucha isn’t just a niche drink—it’s gone mainstream. New U.S. trends include:
- Kombucha on tap at cafes and co-working spaces
- Kombucha cocktails and mocktails in restaurants
- Hard kombucha with up to 7% alcohol content (regulated by the TTB)
- CBD-infused and adaptogenic kombuchas offering stress support
The U.S. Food and Drug Administration (FDA) requires kombucha products containing more than 0.5% alcohol to be labeled accordingly (FDA Alcohol Regulations).
Meanwhile, the Centers for Disease Control and Prevention (CDC) continues to recognize kombucha as “likely safe” when consumed in moderation, while warning that home-brewed versions can pose contamination risks if not made properly (CDC food safety page).
Is Kombucha a Good Alternative to Coffee?
If you’re looking to cut back on coffee but don’t want to go entirely caffeine-free, kombucha might be a great choice. It offers:
- A natural energy boost without the highs and lows of coffee
- Added gut-health benefits from probiotics
- A refreshing taste profile that keeps hydration interesting
Some people even report that kombucha helps them transition off soda or sugary energy drinks, thanks to its carbonation and subtle caffeine kick.
Who Should Watch Their Caffeine Intake?
Although kombucha is generally considered low in caffeine, these groups should keep an eye on consumption:
- Pregnant or breastfeeding individuals
- People with anxiety or sleep disorders
- Those with heart rhythm issues
- Children and teens (in excess)
According to the American Academy of Pediatrics, children should avoid caffeine as much as possible. Opting for caffeine-free kombucha or limiting intake is a safer choice for younger drinkers.
How to Check the Caffeine Content in Kombucha
Since there’s no federal requirement to list caffeine content on kombucha, some brands voluntarily disclose it. Here’s what to do:
- Read the label: Look for “Contains caffeine” or specific mg amounts.
- Check the brand’s website: Many FAQs or product pages list caffeine levels.
- Contact customer service: They’re usually happy to help, especially as consumer interest in caffeine grows.
In 2025, more kombucha companies are embracing full transparency to build trust and meet rising consumer demands for accurate nutrition information.
Final Thoughts: Does Kombucha Have Caffeine? Yes—But It’s Manageable
So, does kombucha have caffeine? Yes, but typically not enough to interfere with most people’s sleep or cause the jitters. If you’re sensitive or trying to avoid caffeine altogether, choose kombucha made with herbal teas or look for caffeine-free labeling.
With its balance of flavor, fizz, probiotics, and just a touch of caffeine, kombucha is holding its spot as a top beverage choice for health-conscious Americans in 2025.
