What Is Kombucha Made From?

In its simplest form kombucha is merely sweetened green or black tea. This based then has bacteria and yeast added to it, this is when the fermentation process begins and the magic happens!

This mix of culture of bacteria and yeast is referred to as SCOBY (Symbiotic Culture of Bacteria and Yeast).

It is this SCOBY that transforms the otherwise regular tea into a carbonated, gut-friendly probiotic, healthy glass of deliciousness.

Despite kombucha being made through a process of fermentation, it does not have any alcohol content, it is purely a grown-up soft drink.

What Does Kombucha Taste Of?

There are many different varieties of kombucha these days, some more fruity than others. The original (plain) version of kombucha is a really difficult taste to describe. It has a more distinct taste than your average soft drink. The first thing that you will notice when tasting it, is its fizzy ‘buzz’, this will soon fill your mouth.

This fizz is a by-production of the fermentation process producing carbon dioxide. It has a zingy taste to it. The original blend is not fruity or floral, so is really difficult to describe. Give it a go and let us know how you would describe the taste in the comments below! ???

Furthermore, don’t be put off by the smell, it can smell slightly acidic a bit like mild vinegar. This is due to the acetic acid which is produced during fermentation.

I know the first time that I tried it I was really skeptical because of the smell alone, but this is not a reflection of how it tastes! This smell is a by-product of the fermentation process.

That is just a brief list of some of the flavors that are available, the flavors available are increasing every day as manufacturers play with this growing favorite.

Kombucha originally was a non-alcoholic drink, however, during the fermentation process, this can be adapted to create kombucha of an ABV of around 14%.

Here, we are discussing the non-alcoholic version, sorry! Check out this article if you want to know more about drinking alcohol on a keto diet.

Health Benefits Of Kombucha

There are numerous health benefits to kombucha. The three main benefits that you should know about are;

  1. Contains Probiotic – Drinking probiotics add healthy bacteria to your gut. These bacteria can have many health benefits. The most common are, improving digestion, reducing inflammation, and even weight loss.
  2. Contains Antioxidants – antioxidants fight the free radicals which can damage your cells and prevent them from repairing.
  3. Contains Healthy Bacteria – acetic acid, which is produced during the fermentation process is able to kill many potentially harmful microorganisms that live in the gut.

In summary, it’s amazing for digestive health and is vegan friendly, and definitely beats the sugary soda drinks that you can buy in the store. A lot of people will drink this as an alcohol-free, carbonated beer alternative.

Negatives To Drinking Kombucha

There are some potential side effects that you should be aware of, especially if you are new to kombucha. If you have any doubt as to whether or not you should be drinking it, please seek medical advice.

  1. May Cause Bloating – due to the ‘fizz’ in kombucha, drinking too much of it can make you feel bloated, just the same as any other carbonated drink.
  2. Consume Excessive Sugar – drinking too much can lead to an intake of an unnecessary amount of sugar, and in turn, calories, which can lead to weight gain. Don’t worry about this though, we’ll show you how to get around this below!
  3. Allergic Reaction – although rare, there have been reported cases of persons being allergic to kombucha
  4. Unpasteurized – Kombucha is unpasteurized, meaning that persons with any health conditions that have been advised not to consume unpasteurized products should avoid it.

Summary: Is regular, pre-made Kombucha Keto Friendly?

‘Regular’ kombucha contains around 5.6 grams of sugar and no fiber, which means it has 5.6 grams of net carbs per serving. Drinking this volume of sugar is likely to rapidly raise your blood sugar levels and knock you out of ketosis.

There are a number of shop-bought options that claim to be keto, however,  the sugar content of these can be really high.

Please ensure that you read the nutritional label before you purchase.

Making Keto Friendly Kombucha

Depending on how you like your kombucha, most people will ferment it for between 7-14 days. However, if you leave it for 21 -30 days (I find 25 days is perfect for me), more of the sugar is ‘eaten’ by the bacteria and yeast during the fermentation process and as such will reduce the number of carbs in the drink.

Once fermented, bottle and place in the fridge immediately, this will stop the fermentation process, otherwise, your kombucha will end up tasting like vinegar.

Serve up with seltzer and if you want to add further flavor or sweetness you can use Skinny Syrups or the like. Mixing it with the seltzer reduces the amount of kombucha that you are drinking, which reduces the number of grams of carbs you will be consuming.

Unfortunately, you cannot use sugar alternatives to create a zero-carb kombucha as the sugar is needed for the fermentation process.

At the moment I am experimenting with reducing the amount of sugar I am supplementing with sugar alternatives to see if I can find the perfect keto kombucha recipe. I will keep you posted.
