København Kombucha

København Kombucha was founded in 2019 in Copenhagen by Louise Benkjær Limbach, who began fermenting as a hobby driven by a love of fermentation before the practice grew into a business. She took fermentation classes and experimented across a range of techniques before kombucha became her main focus, drawing on resources from Aarstiderne and the Noma fermentation book, and worked at Novozymes while spending a few years developing the skills to make an alcohol-free kombucha. According to the company, the inspiration traces back to 2011, when her son Felix was born. Several retail sources describe her as having roots in French and Austrian gastronomy and credit the food cultures of France and Austria as the impetus behind the company.^[1]

The name ties the company to Copenhagen, the city Limbach is from and where the business started. Its kombucha won the Sol over Gudhjem competition on Bornholm in 2019, before the company was formally established. The producer describes itself as among the first to make non-alcoholic fermented drinks specifically for fine dining.^[1]

The company is based in Copenhagen, Denmark, and bottles in Nordhavn, Copenhagen. To scale production and to help achieve fermentation down to 0.0% alcohol, it partnered with a bottling company in Germany. Between 60 and 70 percent of production is exported, to Germany, the Netherlands, Belgium, France, Austria, Switzerland, the Czech Republic and the UK.^[1]

Nicolas Limbach — founder. One 2026 account of the company, described as a Danish craft brewery, names Nicolas Limbach as co-founder alongside Louise Benkjær Limbach in 2019.^[2]

The central commitment is a true 0.0% alcohol reading rather than the regulatory minimum: European Union rules permit beverages labelled non-alcoholic to contain up to 0.5% ABV, and København Kombucha targets 0.0%. Every batch is tested to verify the figure. The company positions its drinks as a premium 0.0% alternative to sparkling wine and to champagne, and states that it pioneers non-alcoholic fermented drinks crafted for fine dining.^[1]

Double fermentation to 0.0%. The company achieves what it describes as true 0.0% alcohol through a natural double fermentation without chemicals, training its bacteria to convert alcohol more fully into acidity. Rosa Rugosa is documented along these lines: bacteria and yeast convert the added sugar in the tea into alcohol, organic acids and other nutrients, giving sparkle and flavour, and after fermentation the alcohol is converted into acids by bacterial cultures. Every batch is tested to confirm the 0.0% result, and Bee Pollen, Hidcote Blue and Rosa Rugosa are all declared at 0.00% ABV.^[1]

Scoby husbandry and starter liquid. A living scoby transforms the simple ingredients into the drink and, the producer says, gives the sparkling tea its signature balance of tang, sweetness and subtle effervescence. The same culture is nurtured and carried from batch to batch. During production the house also uses a scoby starter liquid containing the same yeasts and bacteria as the scoby itself, which helps control the fermentation.^[3]

Flavour from fermentation rather than addition. The producer states that flavour notes such as ginger, apple, strawberry and mandarin peel are not added ingredients but emerge from the fermentation itself. Hidcote Blue is the clearest illustration: the company says the bottling contains neither ginger nor cinnamon, and that its tropical notes come purely from the yeasts used in fermentation, even though ginger and apple dominate its palate.^[4]

Foraged and provenance-driven botanicals. Bottles are infused with Nordic botanicals — lavender, rose petals, bee pollen and juniper among them — all organic and subtly fermented.^[5]

• Bee pollen (Bee Pollen) — cultivated and selected by a partner and expert in Northern Denmark, from Peter Sjøgren's 17 hives, with harvests varying across four bee seasons: spring, early summer, summer, and late summer/autumn. One retail listing instead places the pollen in North Zealand.
• Hidcote Blue lavender (Hidcote Blue) — described as the dominant lavender flower growing in the Nordics.
• Rosa Rugosa petals (Rosa Rugosa) — wild beach rose petals handpicked at a small organic farm in Finland that specialises in growing them; rosehip (hybenrose) also features.
• Cherry flower (Cherry Blossom) — with hibiscus.
• Elderberry flower at 0.21% and ginger at 1.04% (Summer Haze).
• Sea buckthorn at 2.8% and hawthorn at 0.26% (Silent Shore), over an apple juice base.
• Aronia juice at 9%, cherry juice, oak bark at 0.17% and hibiscus at 0.08% (Nordic Grove).
• Hops at 0.10%, chamomile at 0.39% and lime (Brew & Bloom).

Pollen trapping and freezing. The bee pollen for Bee Pollen is gathered by bees while collecting nectar, then taken with special pollen traps that gently capture part of the load as the bees return to the hive. Peter Sjøgren harvests every evening from his 17 hives and freezes the pollen immediately to preserve freshness, flavour and nutritional qualities.

In the company's early phase, Michelin-starred chef Francis Cardenau invited Louise Benkjær Limbach to use his kitchen to produce kombucha. For scale and for the fermentation work needed to reach 0.0% alcohol, the company partnered with a bottling company in Germany.

København Kombucha's kombucha took first place at the Sol over Gudhjem competition on Bornholm in 2019, before the company was formally established; the winning bottling was the lavender kombucha Hidcote Blue, which retail listings date to the same year it launched.^[1]

At Falstaff's 2025 tastings, Rosa Rugosa scored 92 points in the Sparkling Special and Bee Pollen 92 points in the Non-alcoholic Beverages Trophy, with Hidcote Blue at 90 points in the same trophy.

In a Jyllands-Posten assessment by Morten Bundgaard, both Hidcote Blue and Rosa Rugosa were scored 91 out of 100 and rated "Fremragende"/Outstanding. Among 29 alcohol-free products tested, the two were ranked jointly as the best wine alternative, with only one alcohol-free wine scoring higher.
