Kombucha coffee in London
1 speciality roast from 1 London roaster feature kombucha notes.
Kombucha as a coffee flavour note presents a lightly tangy, fermented brightness with a subtle effervescence on the palate, often accompanied by a mild vinous or fruity acidity. It differs from sharp sourness in that it carries a rounded, almost tea-like quality alongside the fermented character. This note typically arises from extended or experimental fermentation during wet or anaerobic processing, where wild or introduced microorganisms produce acetic and lactic acids that carry through to the cup.
Kombucha-processed coffees carry a distinctly tangy, lightly fermented character, with a bright acidity and a curious effervescence on the palate that recalls the drink itself. The single London roast featuring this note comes from Colombia, where the beans undergo anaerobic processing, a method that creates a sealed, oxygen-free fermentation environment allowing complex, unconventional flavours to develop. Kiss the Hippo are currently the only roaster in the city offering this unusual expression.

How kombucha notes develop
This note is often associated with coffees from Ethiopia and Colombia, where producers are increasingly experimenting with controlled anaerobic and extended fermentation methods. East African naturals and washed lots subjected to longer fermentation windows can also exhibit this quality, particularly when ambient temperatures and microbial activity are carefully managed. Processing style tends to matter more than geography here, so the note typically signals an intentional fermentation-forward approach rather than a characteristic of a specific terroir.
What to look for
On a bag or cafe menu, look for descriptors such as "fermented", "wild ferment", "anaerobic process", or references to kombucha, kefir, or lacto-fermentation alongside fruity or floral notes. Brew methods that preserve delicate acidity and complexity tend to show this note most clearly, with filter methods such as pour-over or Chemex generally doing so more faithfully than espresso. A lighter roast level is also a useful indicator, as heavier roasting tends to suppress the subtle fermented character that defines this note.
