A speciality coffee flavour note across London.
Crab apple in the cup presents as a sharp, tart acidity with a slightly astringent edge, reminiscent of the small, hard fruit rather than the sweeter acidity of a cultivated apple. The sensation tends to sit at the front of the palate and lingers with a clean, dry finish that can carry faint floral or green fruit undertones. This character is generally associated with high levels of malic acid in the bean, which is typically more pronounced in lighter roasts where delicate organic acids are preserved rather than driven off by heat.
This note is typically found in coffees from high-altitude East African origins, particularly Ethiopia and Kenya, where the combination of cool growing temperatures and distinct wet seasons tends to concentrate bright, complex acids in the cherry. Washed and natural processed Kenyan coffees, often grown at elevations above 1,700 metres, are often cited as producing this kind of sharp, tart fruit character. The note can also appear in some Central American washed coffees, particularly those from Guatemala or Colombia, though the expression there is often softer and less pronounced.
When scanning a bag or menu, look for descriptors that suggest bright or sharp acidity alongside fruit notes such as apple, citrus, or redcurrant, which frequently appear alongside crab apple as part of a broader tart fruit profile. A light or filter roast designation is a reliable indicator, as crab apple acidity tends to be softened or lost at medium to dark roast levels. Filter brewing methods, particularly pour-over or Chemex, are well suited to highlighting this note, as they allow the clean acidity to express itself without the additional body or bitterness that espresso extraction can introduce.
