A speciality coffee flavour note across London.
Mushroom as a flavour note in speciality coffee presents as an earthy, savoury depth rather than anything sharp or pungent, often described as a quiet umami quality that sits beneath the primary fruit or chocolate notes. It can evoke dried porcini or forest floor, giving the cup a rounded, almost brothy quality on the finish. This character typically arises from certain bean varietals, natural or anaerobic processing methods that encourage fermentation-derived compounds, or roast profiles that draw out the coffee's more reductive, earthy chemistry.
Coffees from Indonesia, particularly Sumatra and Sulawesi, often carry mushroom-adjacent notes as a result of the wet-hulling process, known locally as Giling Basah, which encourages distinctive earthy and savoury compounds to develop. Some naturally processed coffees from Ethiopia's older heirloom varietals can also exhibit this quality, typically as a secondary note alongside fruit-forward characteristics. Robusta-influenced blends and coffees grown at lower elevations often produce more pronounced earthy tones, of which mushroom is a recognisable expression.
On a bag or cafe menu, look for tasting notes that include earthy, umami, forest floor, or savoury alongside descriptors like dark chocolate or tobacco, as mushroom tends to appear in that flavour cluster. Origin callouts for Sumatra or Sulawesi, or processing notes indicating wet-hulled or natural fermentation, are reliable indicators. Brew methods that produce fuller-bodied, less filtered cups, such as French press or moka pot, tend to allow these earthy, savoury qualities to come through more clearly than lighter methods like V60.
