Caffeine In Kombucha: How Much Is It & Can It Replace Coffee?

Caffeine is a substance that can be a friend or foe to your health. Most people are in love with its energy-boosting effect but it also makes anxiety worse for those suffering from the condition. As kombucha infiltrates the health space, the caffeine in kombucha is one of the frequently asked questions from recovered caffeine addicts and caffeine-sensitive individuals. 

In this post, we will share the amount of caffeine in kombucha and how much it differs from the caffeine in common caffeinated food and drinks like coffee, chocolate, and energy drinks. Since kombucha brands do not include caffeine content in their labels, we created a comprehensive list to serve as a buyer’s guide. 

Does kombucha have caffeine & how much is it?

Kombucha is made of sugar, tea, water, and starter culture. The teas used in making kombucha are black, green, and white tea, which all contain 28mg to 47mg of caffeine. Most brewers believe that during the fermentation process, the yeast and bacteria in SCOBY feed on the caffeine and sugar and turn it into ethanol. 

After the fermentation process, the caffeine left in kombucha is only one-third of its pre-fermentation values. So, if the sweet black tea contains 40mg of caffeine before the first fermentation, the caffeine content of kombucha is 13.32mg.

One brave kombucha enthusiast, Michael R. Roussin seeks to debunk the truth behind the relationship between SCOBY and caffeine. In his research, he found that the caffeine in kombucha is the same amount leached from the tea during the pre-fermentation phase. 

Whether it’s true that yeast and bacteria feed on caffeine or not, it’s still a fact that there are some traces of caffeine in kombucha. The source and the reduced amount of caffeine are just the hazy part of the process and are still under an ongoing debate. 

Going back to the caffeine in kombucha, you’re probably wondering if 20mg to 40mg is too much or at par with coffee. Well, it’s significantly lower than you think. Check out the comparison of caffeine in kombucha and coffee below:

To give you some context, the daily recommended caffeine intake is 400mg. If you love buying coffee in your local coffee shop every morning, the range that you might be consuming is roughly around 48mg to 317mg, according to a study

As for kombucha, a 16 oz. store-bought bottle of kombucha may contain around 4mg to 58mg. If we bring in some math, your average cup of coffee contains  81% to 91% more caffeine than kombucha. If a cup of coffee doesn’t cause any jittery feeling, then your body won’t likely experience any side effects. 

Effects of caffeine in kombucha on the body

Each person has a different caffeine sensitivity. A cup of Arabica brewed coffee can make one person feel energized while making the other anxious and restless. The good news is there’s a difference in the effects of caffeine in kombucha and coffee. Interesting isn’t it?

Aside from having less caffeine than coffee, the black and green tea used in kombucha both contain a relaxing substance called L-theanine. Have you ever wondered why even if it has caffeine, people often go for a cup of tea to calm down and relax? It’s because L-theanine works with caffeine to perform its mood-altering prowess.

The combination of L-theanine and caffeine in the tea added in kombucha provides the following benefits:

  • Lower levels of stress hormones and cortisol.
  • Lower risks of developing dementia and depression.
  • Induces a sense of calm without being sleepy.
  • Improves alertness and cognition.

In summary, the effect of caffeine in kombucha can give you the perfect balance of energy to get through the day and a sense of calm against the daily anxieties of life. Kombucha is also low in calories and sugar, making it a perfect healthy alternative to coffee. 

What affects the caffeine levels in kombucha

If you are home brewing kombucha, it can be hard to gauge its caffeine levels.  There are some factors involved that may cause varying caffeine content in homebrewed kombucha. These include:

  • Length of time the tea is steeped. 
  • Type of tea used and how it is harvested (Peak season tea harvests contain more caffeine).
  • Water temperature when the tea is steeped.
  • Water and tea leaf ratio.

Kombucha offers a wide selection of flavors that you can enjoy. It can help restore the joy of enjoying some delectable but low-in-caffeine drinks for people with anxiety disorders, especially if they hate the unpleasant taste of decaffeinated drinks. 

While kombucha offers an attractive set of potential health benefits, caffeine-sensitive individuals must consider taking some precautions. For a more calculated caffeine intake, it’s best to opt for store-bought kombucha that indicates the amount of caffeine on its label or the company’s website.
