Given that OMBucha® Kombucha is brewed using tea, we’re frequently asked “How much caffeine is there in each bottle of Kombucha?”.
Caffeine: The Basics
Let’s start with a basic pharmacology lesson on caffeine and why it’s so heavily scrutinised.
Caffeine is a central nervous system (CNS) stimulant. It’s most commonly consumed in modern society via coffee beans, although it’s widely acknowledged that tea contains a significant amount of caffeine too depending on the origin and type of tea you’re consuming.
The contention with caffeine is the positives VS negatives: consume a reasonable amount, and you can reap many benefits such as enhanced metabolic rate, and even the potential to protect against various diseases given that it’s found within antioxidant-based products in its natural state.
The negatives of overuse of caffeine include anxiety, sleep deprivation and enhanced heart rate/blood pressure, which is what most users are generally concerned with.
The threshold dosage to reach these positives and negatives is often the cause of fierce debate which we will avoid for the sake of simplicity. However, it’s widely acknowledged that under 200 mg for the average adult per day is a sensible limit on caffeine consumption to reap its benefits without any of the adverse side-effects.
Caffeine in OMBucha® Kombucha
Back to our lovingly crafted homemade ‘booch.
At OMBucha®, we use a blend of black tea (around 20%), green sencha and a delicate balance of other hand-picked teas depending on time of the year it’s picked, origin and quality available to us when importing the product.
What is interesting about tea is that the variation of caffeine is greatly influenced by several factors, including:
- How long it’s steeped for in the brew
- Origin of the tea and time of year it’s picked
- Storage time of the tea leaves
- Natural variation between tea leaves
There are other factors that influence caffeine content in tea, but these are some of the main ones.
With that being said, when fermented correctly, the caffeine content is greatly reduced in the overall product leading to a modest amount of caffeine in each kombucha you consume.
L-Theanine: The Modulating Amino Acid
Interestingly, tea also contains a significant amount of the amino acid L-Theanine, which exerts a strong modulating effect on caffeine in antagonising its stimulatory effects.
This may be a huge benefit to people worried about jittery feelings and anxiety consuming kombucha: the L-Theanine content effectively allows you to reap the benefits of caffeine kombucha while simultaneously reducing the anxiety that overconsumption may provide.
And, given that OMBucha® kombucha only contains a mild amount of caffeine per serving (as you’ll see below), it’s unlikely this will be an issue anyway.
The Lowdown: How Much Caffeine is in OMBucha® Kombucha?
Roughly 50-60 mg per 250 ml of product, and 100 mg per 500 ml (full bottle).
With the aforementioned variables, it’s important to note that this is a rough estimate and not a set-in-stone figure. However, with a passionately brewed kombucha made at home that undergoes a meticulous fermentation process such as ours, the likelihood is that it’s on the lower side of the scale.
In conclusion: consume OMBucha® Kombucha with confidence, and don’t worry about the caffeine content too much!
