Kefir Water vs. Kombucha – Choosing Your Liquid Probiotic


Kefir and kombucha are fermented drinks known for their health benefits, yet they differ in production, nutrition, flavor, and texture. This review aims to highlight the distinctions between water kefir and kombucha, assisting you in choosing the beverage that aligns better with your health preferences.

What is water kefir?

Kefir water grains, known as tibicos in Mexican culture, have been cherished for centuries as the foundation for crafting this timeless fermented beverage. These age-old tibicos grains play a pivotal role in the creation of our delightful Agua de Madre kefir water.

In contrast to kombucha’s botanical and slightly bitter profile, kefir water boasts a more robust and hoppy flavor, coupled with a delightful effervescence. Unlike kombucha, kefir water carries less bitterness, readily absorbing the fruity essence with which it’s brewed.

While kombucha derives its essence from tea, offering caffeine along with beneficial antioxidants, enzymes, and acids, kefir water stands apart since it doesn’t have caffeine. Instead, it embraces trace amounts of alcohol (<1.2% abv) as a cheerful by-product of the fermentation process.

Is water kefir a type of kombucha?

No, kombucha and kefir water are not the same; they’re more like distant cousins in the world of fermented beverages. Despite both being probiotic-rich and fermented, they have distinct flavors and textures. Kombucha is created by fermenting green or black tea with sugar and often adding fruits or berries, resulting in a slightly fizzy, faintly acetic drink. The kombucha scoby, or symbiotic culture of bacteria and yeast, transforms most of the alcohol and some sugar into beneficial acids, providing approximately 100 million live cultures per 100 ml.

In comparison, kefir water, like Agua de Madre, uses small, clear, and crystalline kefir grains, not a scoby. With a whopping 55 billion live cultures per 100 ml, kefir water is a top choice for those seeking to boost their gut’s live culture count.

Aqua kefir vs. kombucha starter culture

The starter culture for Kombucha is a harmonious assembly of bacteria and yeast, forming a symbiotic colony, often abbreviated as SCOBY. This unique entity is bound by polysaccharides and, despite its mushroom cap resemblance, it’s essential to note that it isn’t a fungus, even though it’s sometimes colloquially referred to as a mushroom. Kombucha boasts a diverse composition of bacteria and yeast, contributing to its distinctive characteristics.

Water kefir grains consist of a community of bacteria and yeast, but they present a distinct appearance—tiny and translucent. The term “grains” merely characterizes their look and does not imply the presence of traditional grains like wheat or rye. Contrary to the name, water kefir grains are not grains in the cereal sense. They are acknowledged for harboring a diverse range of bacteria and yeasts, contributing to their unique composition and qualities.

Kombucha vs. water kefir preparation

To craft Kombucha, one combines starter tea and a Kombucha culture (SCOBY) with sweet tea, allowing the blend to ferment for a period of up to 30 days. On the other hand, the creation of water kefir involves introducing water kefir grains into a mixture of sugar water, fruit juice, or coconut water, and then allowing the culture to develop over a span of 24-48 hours.

What does each beverage taste like?

Kombucha exhibits a distinctive profile, characterized by its tangy and slightly sweet notes, often accompanied by a gentle effervescence. The flavor spectrum varies significantly based on the duration of fermentation and the type of tea employed. The culturing period dictates whether the resulting kombucha leans towards a subtle, mild taste or a more pronounced, vinegar-like intensity.

When enjoying kombucha, you can savor it as it is, or for a twist, experiment by incorporating juice or fruit to create unique kombucha flavors.

On the other hand, water kefir’s sweetness is influenced by the sugar utilized during the culturing process. To enhance the appeal of plain water kefir, it’s advisable to infuse it with flavors before consumption, as its natural taste might not be particularly palatable without additional enhancements.

What are the nutritional values of each drink?

The fermentation methods employed in crafting kefir and kombucha result in beverages rich in probiotics, those beneficial bacteria crucial for both food and digestive system health. These microorganisms play a pivotal role in fostering a healthy gut and overall well-being. However, the specific types and quantities of good bacteria in kefir and kombucha differ slightly. Both beverages incorporate lactic acid bacteria, with kombucha additionally featuring acetic acid.

The nutritional content of these drinks can vary significantly based on factors such as the type of milk used in kefir and the amount of added sugar in kombucha. While the nutrient composition fluctuates, offering a glimpse into their nutritional values, a comparison can be made between 1 cup (240 mL) of kefir crafted with low-fat dairy milk and an equivalent serving of kombucha.

Which should you drink?

Both kefir water and kombucha offer unique health benefits. Kombucha is packed with antioxidants that combat free radicals, while kefir water boasts over 30 strains of beneficial bacteria and yeast, supporting gut health by surviving the journey through the gastrointestinal system. Although both beverages have similar calorie counts, kefir water becomes an excellent choice if you’re aiming to steer clear of caffeine or prefer to avoid the distinct taste of kombucha. So, whether you’re seeking antioxidant support or diverse probiotics, these drinks cater to different health preferences.

Can you drink kombucha and kefir in the same day?

There are no strict rules about when to drink them, as both kefir water and kombucha are liquid probiotics. However, it’s advisable not to have both in a single meal, as they’re both sweetened beverages. It’s crucial to be mindful of sugar intake, so enjoy them separately to avoid consuming excessive sugar in one sitting.
