Kombucha vs Water Kefir





Which is better for you?

When it comes to drinking healthy, many of us consider a number of factors when choosing what to drink in order to gain all the health benefits that comes with a healthy beverage. Some of these factors are; how the drink is made, nutritional benefits, flavour and texture. While both these drinks are fermented, they have some differences in terms of production, nutrition and taste. This article will review the differences between water kefir and kombucha to help you decide which one is right for you.


The most obvious difference in the way kombucha and water kefir is made is with the cultures used. Both use a live culture to create a colony of bacteria and yeast during the fermentation process. Kombucha is made with a symbiotic colony of bacteria and yeast (scoby), while water kefir is made with a grain-like culture of bacteria and yeast. Both these cultures produce a very different result, yet they are highly probiotic because they have undergone fermentation, whereby the bacteria, yeasts and other microorganisms break down sucrose into fructose and glucose molecules (or sugar), which feed the yeast and which in turn feeds the bacteria that ultimately feeds you. This sugar conversion is what makes these probiotic drinks so good for you, and which makes both these drinks a low sugar alternative to soft drinks, sodas, energy drinks and even alcohol. More notably, the main difference between the two drinks, is that kombucha has a sweet tea base, while water kefir has sugar water base. Both create a nutritious and delicious beverage when the balance of flavours is achieved through the fermentation process.

Nutritional Benefits: Pros & Cons

The nutritional composition of kombucha and water kefir can vary depending on the ingredients used to make them. Both drinks contain probiotics, that include lactic acid bacteria and acetic acid. These drinks provide a rich source of probiotics, which are the good bacteria that help promote a healthy bacterial balance in your digestive tract. Both kombucha and water kefir are packed with natural probiotics that promote good gut and overall health. Many people see varied results when consuming these drinks regularly. This is because they contain antimicrobial, antioxidant, anticancer and anti-inflammatory i.e. good fighting bacteria. Other effects of drinking these health drinks, is that people experience natural weight loss due to regular consumption causing an increase in their metabolism. Kombucha contains natural caffeine that has also been linked to weight loss, while water kefir is made with kefir grains that make you feel fuller, which makes you eat less.

The only downside that you may experience from these drinks is initially when adjusting to drinking them. You may feel a tummy upset from kombucha because your stomach may need to get use to the acetic acid (i.e. vinegar base) that is created during the natural fermentation process. This is usually not serious, if you don’t drink it on an empty stomach or consume more than the daily recommended dosage. Kombucha may also be problematic for people with caffeine sensitivity and should be limited. It is not recommended for pregnant or breastfeeding women because it does contain a very small amount of alcohol. Water kefir is generally easier to adjust to because it is not as tart as kombucha, however drinking too much water kefir may inhibit weight loss as it is rich in protein, but this is nothing to worry about. The most beneficial reason for drinking these highly probiotic drinks, is that they are low in sugar and provide many health benefits that outweigh the downsides. Even better is that ISIKO kombucha and water kefir has a clean, fresh and authentic taste because it is made the traditional way. You can taste the difference and if you’re anything like me, you’ll find that once trying these probiotic beverages, you no longer reach out for a soft drink but for a kombucha or water kefir instead.

Taste, Texture and Flavour

Because ISIKO kombucha and water kefir are fermented drinks that are batch-brewed, we know exactly what goes into our drinks, and therefore we can control the consistency and taste of our probiotic beverages. We use purified water and only natural and organic ingredients in our brews, so you get the fresh, clean and refreshing notes of the drink. An authentic kombucha should have a light tart taste that is not too overpowering and that marries well with the natural fruit flavours added to it to give it an enhanced aroma. Water kefir, on the other hand, has a sweet effervescent taste with natural carbonation that tastes so good it could be mistaken for a lemonade, yet it is ten times better for you!

In terms of texture, both kombucha and water kefir have a thin texture. Kombucha can have a vinegar-rich aroma and a slight bitterness as it ferments. This is because it is usually carbonated and fizzed to enhance the taste. A good kombucha should have the balance of flavours just right and not be too tart. The sour notes come from the carbon dioxide molecules that result from acetic acid and other gases being released during the fermentation process. Kombucha is very versatile as it comes in a wide range of flavours. Traditionally made kombucha is easily identifiable particularly in flavouring. ISIKO kombucha is made using real fruit and natural flavours. It does not contain any artificial additives, enhancers, preservatives or colourants.

Water kefir has a rich, delightfully sweet flavour that is as a result of using healthy, well-fed grains. ISIKO water kefir grains are cultivated and fed with minerals in order to give you a rich-tasting yet extremely probiotic beverage. In order to keep the grains healthy, we feed our grains sugar water until it is at the right consistency and taste. The sugar water needs to changed every 24-48hrs so that the grains do not starve. As it cultures, the grains consume the sugars and convert them to carbon dioxide (carbonation), acids, bacteria, and yeasts. This makes it a great low sugar drink because as the kefir grains ferment, the sugar is dramatically reduced. If you are wanting to avoid unnecessary sugar, both these health drinks can be substituted for your favourite sodas as they make a great, refreshing beverage and you don’t even have to compromise on taste.

Which To Choose?

Which one is healthiest may depend on what you’re looking to get from consuming these beverages. In the end, which one you choose may depend primarily on your personal preference. In any case, it’s a good idea to read the ingredients label and nutrition facts panel when deciding between the two or which brand to try.
