In recent years, the range of beverages available has changed significantly. In addition to classic soft drinks, more and more fermented beverages and so-called functional lemonades are available in supermarkets today. Particularly popular are kombucha, kvass, and modern lemonades with added fiber or fermented cultures.
But how do kombucha, kvass, and functional lemonades really differ? And which drink is healthier, more suitable for everyday use, and reasonably priced?
1. Differences between Kombucha, Kvass, and Functional Lemonades
Kombucha – fermented tea with a light acidity
Kombucha is a fermented tea drink made from tea, sugar, and a SCOBY culture. During fermentation, natural acids, light carbonation, and a slightly sour taste are produced.
Typical properties of kombucha:
- Base of black or green tea
- Lightly sparkling and sour
- Contains fermented cultures
- Often with fruit or herbal flavors
Kombucha is often chosen as an alternative to classic soft drinks and is particularly suitable for people who prefer less sugary drinks.
Kvass – traditionally and intensely fermented
Kvass is a traditional fermented beverage based on whole grain bread or grain fermentation.
Typical properties of kvass:
- Made from fermented whole grain bread
- Very sour, tart taste
- Naturally cloudy and unfiltered
- Very strong fermentation
Kvass has a very intense taste and is less easy to drink than modern beverages, but it is a classic traditional fermented drink.
Functional lemonades with fiber
Functional lemonades are modern soft drinks that are often enriched with fiber such as inulin or additional ingredients.
Typical properties:
- Fruity, sweet taste
- Less sugar than classic lemonades
- Partially fiber or added cultures
- Very suitable for everyday use
They are particularly interesting for people who are looking for a healthier alternative to cola and classic soft drinks without sacrificing taste.

Functional Lemonades
Functional lemonades are not always fermented, but often contain fiber.
Properties:
- Often with inulin or similar fibers
