The Global Star: What is Kombucha?
Kombucha is the fizzy, slightly sweet-and-sour fermented tea that has become a global wellness icon. Made by fermenting sweetened black or green tea with a Symbiotic Culture of Bacteria and Yeast (SCOBY), its origins are somewhat murky but are believed
to trace back to ancient China. The SCOBY, a rubbery, pancake-like disc, is the powerhouse that transforms the tea into a beverage rich in organic acids and potential probiotics. Its popularity in Indian towns and cities has skyrocketed, driven by a growing class of health-conscious consumers seeking alternatives to sugary sodas. Artisanal brands are now a common sight, offering a wide array of flavours and catering to a demographic willing to pay a premium for what they see as a functional, gut-friendly drink.
The Desi Classic: Rediscovering Kanji
Long before kombucha entered the Indian lexicon, there was Kanji. This traditional North Indian fermented drink is most famously made with black carrots (kali gajar), water, salt, and coarsely ground mustard seeds. Typically prepared in households during the winter and leading up to the Holi festival, the mixture is left to ferment in the sun for several days. This process gives Kanji its distinctive tangy, savoury, and slightly pungent taste, with a deep ruby or purple hue. Unlike kombucha, Kanji's fermentation is spontaneous, relying on the naturally present microbes on the vegetables, primarily lactic acid bacteria. This makes it a simpler, caffeine-free beverage deeply rooted in Indian culinary wisdom.
The Probiotic Showdown
Both drinks are celebrated for their probiotic content, which is beneficial for gut health. Kombucha boasts a diverse mix of bacteria and yeast strains from the SCOBY. However, the probiotic benefit of commercial kombucha can be a mixed bag; pasteurisation to extend shelf life can kill these live cultures. Kanji, on the other hand, is a product of lacto-fermentation, dominated by hardy probiotic strains like Lactobacillus plantarum, which are believed to be well-suited to survive the journey through the digestive system. While kombucha may offer a broader spectrum of microbes, Kanji provides specific strains that are particularly effective and have long been part of the traditional Indian diet.
A Clash of Flavours
The taste profiles of kombucha and Kanji are worlds apart. Kombucha is effervescent and can range from sweet to vinegary, depending on the fermentation time and added flavourings like fruits and spices. Its tea base provides a familiar foundation. Kanji, in contrast, is savoury, salty, and earthy, with a sharp kick from the mustard seeds. It's an acquired taste for some, often described as a tangy, spiced brine rather than a sweet beverage. Kanji is also naturally low in sugar, as the fermentation process consumes the natural sugars from the carrots, whereas kombucha starts with added sugar, not all of which may be fermented out.
Kitchen Tradition vs. Cafe Trend
The revival of these two drinks speaks to a larger cultural shift. Kombucha represents a global wellness trend embraced by urban India, with the market size expected to grow significantly. It's a premium, aspirational product often discovered in cafes, restaurants, and upscale grocery stores. Kanji's comeback is more of a grassroots revival—a return to traditions and grandmother's wisdom. It’s a celebration of local, seasonal ingredients and simple, home-based fermentation. As consumers become more interested in sustainable and indigenous food systems, Kanji offers a powerful, cost-effective alternative to its more commercialised global counterpart. The rise of both signifies a growing desire for functional beverages, but they cater to slightly different sensibilities: one driven by global trends and the other by a rediscovery of local heritage.
