1 speciality roast from 1 London roaster feature malic acidity notes.
Malic acidity presents in the cup as a clean, mid-weight sourness reminiscent of green apple, pear, or sometimes underripe stone fruit, with a soft finish that tends not to linger sharply on the palate. It differs from citric acidity in that it feels rounder and less bright, sitting more towards the centre of the tongue rather than at the sides. Malic acid is a naturally occurring compound in coffee cherries, and its presence in the cup is typically associated with lighter roast profiles, which preserve organic acids that darker roasting would otherwise break down.
Malic acidity introduces the crisp, apple-like character often found in coffees from Panama, particularly those processed using the natural method where fruit contact influences the bean's final profile. Colonna's offering with this distinctive note reveals how careful processing can coax these refreshing, fruit-forward qualities into the cup, creating a coffee that feels clean and gently tart on the palate.

Processing methods associated with malic acidity notes in London roasts.
Coffees from high-altitude East African origins, particularly Ethiopia and Kenya, often carry notable malic acidity, though it is also found in certain Central American lots from countries such as Guatemala and Honduras. Washed and natural processed coffees can both express this note, though washed processing typically allows the acidity to read more clearly against a cleaner background. Varieties with higher inherent sugar and acid development, such as some heirloom Ethiopian cultivars and SL28, are often associated with pronounced malic character.
On a bag or menu, look for tasting notes that reference apple, pear, or green grape, as these descriptors are commonly used by roasters to signal malic acidity. It is worth checking that the roast is described as light or filter roast, since medium or dark roasts tend to suppress the note considerably. Filter brew methods such as pour over and Chemex generally allow malic acidity to express itself clearly, as they produce a clean, transparent cup that does not obscure delicate acid structure.
