Rhubarb coffee in London
2 speciality roasts from 2 London roasters feature rhubarb notes.
Rhubarb as a coffee flavour note presents as a sharp, fruity acidity with a distinct tartness that sits somewhere between a bright red fruit and a more astringent, stewed quality. In the cup it often carries a subtle sweetness beneath the sourness, much like cooked rhubarb rather than the raw stalk, giving the coffee a rounded but lively character. This note typically arises from specific organic acids present in the green bean, and is most commonly associated with lighter roast profiles where those acids are preserved rather than driven off by heat.
Rhubarb in coffee arrives as a bright, tart tang — think freshly cut stalks with a underlying sweetness that lingers on the back of the palate. In London's speciality scene, this note appears in just two approved roasts, both tracing their roots to Kenya, where the country's high-altitude growing conditions and clean washed processing coax out that distinctively sharp, fruit-forward acidity. Kiss the Hippo and Horsham are the roasters currently bringing this characterful note to the cup.

How rhubarb notes develop
Rhubarb notes are often found in coffees from East African origins, particularly Ethiopia and Kenya, where the combination of high altitude, distinct varietal genetics, and nutrient-rich soils tends to produce pronounced fruit-forward acidity. Natural and anaerobic processing methods can amplify this quality, as extended contact between the bean and fruit pulp encourages the development of complex, tart fruit compounds. Washed Ethiopian coffees, however, also often express a cleaner version of this note, where the rhubarb character reads as a precise, tea-like tartness rather than a deeper, fermented fruit quality.
What to look for
When scanning a bag or cafe menu, look for tasting notes that include rhubarb alongside related descriptors such as redcurrant, tamarind, hibiscus, or cranberry, as these tend to cluster together in coffees with high malic or citric acid content. A light roast designation is a reliable indicator that the acidity required for this note has been preserved during roasting. Pour-over and filter brew methods generally show rhubarb notes most clearly, as they allow the brighter, more delicate acid compounds to come through without the heavier body that espresso extraction can introduce.
