A Look at the Popular Sparkling Beverage

Kombucha, the sparkling fermented tea, has become a beloved beverage amongst the health-conscious community. This beverage, with its origins stretching back 2,000 years to China, has experienced a modern resurgence due to its numerous health benefits, particularly those linked to digestion and gut health. But there's one question that bubbles up often: what about its caffeine content?


Caffeine: A Natural Stimulant

Caffeine, a natural substance found not only in coffee but also in tea, cacao plants, and some soft drinks, is a renowned alertness booster, featuring heavily in our daily lives. In fact, over half of all American adults consume more than 300 mg of caffeine every day. To give you a snapshot of what this looks like, here's the typical caffeine content in some common items:

  •  A cup of brewed coffee: 96 mg
  • A cup of decaffeinated coffee: 2 mg
  • A cup of tea: 47 mg
  • A can of regular cola: 22 mg
  • A can of energy drink: 29 mg


What is a Kombucha Scoby?

Kombucha: A Balance of Energy and Calm

Given that Kombucha is brewed using tea (green, black, white, or oolong), it naturally contains caffeine. However, the caffeine content in Kombucha is relatively minimal, averaging around just 15mg per serving – barely noticeable even to those sensitive to caffeine.

This balance is achieved through the fermentation process, where yeast and bacteria naturally consume the caffeine. The longer the fermentation, the lower the caffeine content. This property of Kombucha makes it a fantastic option for those looking to reduce their daily caffeine intake while still enjoying a little energy boost.

And there's more! Unlike coffee, which can raise anxiety levels, tea – and by extension, Kombucha – has a calming effect on the drinker. This is due to the presence of the amino acid L-theanine, which works against caffeine's stimulative effects, resulting in a calming effect 30-40 minutes after ingestion.
