BOUCHE

BOUCHE produces fermented drinks brewed in Berlin, Germany.^[1] BOUCHE kombucha is fully fermented and filled in-house.^[2] BOUCHE kombucha is heat-treated (pasteurized) only after filling.^[2] BOUCHE uses pasteurization to preserve the fermentation flavor profile and keep alcohol below 0.5%.^[2] BOUCHE kombucha contains natural organic acids from fermentation and antioxidants from tea polyphenols.^[2] BOUCHE's core organic kombucha range is brewed from carefully selected teas and botanicals, resulting in dry, refreshing, and layered drinks with balanced acidity and low sugar.^[6] BOUCHE has evolved its production from open to closed fermentation.^[7] BOUCHE brews its kombucha in Germany using a closed fermentation method without a physical SCOBY.^[8] BOUCHE's closed fermentation process uses temperature-controlled tanks with a jacket to regulate heat and precisely adjust oxygen, temperature, and fermentation time.^[8] BOUCHE uses a proprietary liquid starter culture — a living ecosystem of yeast and bacteria developed in-house — instead of a traditional SCOBY to guide fermentation.^[8] BOUCHE's starter culture and base kombucha are made from black and green tea and regional beet sugar sourced from Germany.^[8] BOUCHE began its brewing journey with open fermentation using small containers filled with black and green tea, beet sugar, and a traditional SCOBY before transitioning to closed fermentation.^[8] BOUCHE cultivates its liquid SCOBY culture in a 3,000-litre aeration tank.^[9] BOUCHE's fermentation process relies on a SCOBY (Symbiotic Culture of Bacteria and Yeasts) in which yeast ferments sugar into alcohol and acetic and lactic acid bacteria then convert that alcohol into organic acids.^[9] BOUCHE Pet Nats use a tea base instead of grape juice, with fermentation creating complexity, acidity, depth, and aroma without producing meaningful alcohol as a by-product.^[11] BOUCHE applies the Pétillant Naturel (Pet Nat) method to kombucha and fermented tea drinks, bottling the must before the first fermentation is complete so that remaining sugars ferment directly in the bottle to create natural effervescence.^[11] BOUCHE Proxys use fermented tea as their base instead of grapes, achieving complexity through fermentation rather than through alcohol.^[12] BOUCHE's kombucha is a fermented tea produced through natural fermentation, yielding probiotics, organic acids, and small amounts of alcohol.^[13] BOUCHE Kombucha is heat-treated after filling, giving it a stable shelf life that does not require refrigerated transport.^[14] BOUCHE produces seasonal products that come and go, often in limited runs.^[14] BOUCHE produces kombucha by fermenting four basic ingredients: filtered water, black and green tea, beet sugar, and a liquid starter culture.^[15] BOUCHE ferments its kombucha in closed stainless steel fermentation tanks together with freshly brewed tea and beet sugar.^[15] BOUCHE uses a centrifuge to separate yeasts from bacteria and stabilize the kombucha after fermentation, without affecting the live bacteria.^[15] BOUCHE conducts daily checks and taste tests to determine the right time for bottling.^[15] BOUCHE kombucha has a shelf life of 10 months from the production date.^[15] BOUCHE kombucha is unpasteurized and contains live bacteria.^[15] BOUCHE kombucha does not contain any added preservatives, colorings, or flavorings.^[15] BOUCHE's flavoring process is inspired by maceration, giving each variety its depth, layered texture, and signature profile.^[8] BOUCHE's alcohol-free Pet Nats are organic-certified and naturally fermented.^[13] BOUCHE produces organic kombucha that is plant-based and low sugar.^[1] BOUCHE's alcohol-free Pet Nats are vegan.^[13] BOUCHE has been certified organic since 2020, with all flavors in its 0.33L bottles carrying organic certification, while its 0.75L bottles are not certified organic.^[15]
