A speciality coffee flavour note across London.
Rum as a flavour note in speciality coffee describes a warm, rounded sweetness with a faint alcoholic depth, evoking dark sugar, molasses, and a gentle barrel-like richness. In the cup it sits somewhere between brown sugar and dried fruit, often accompanied by a smooth, full body and a lingering warmth on the finish. This character typically arises from the presence of fermentation-derived compounds in the bean, particularly when processing encourages extended contact between the coffee seed and its mucilage or fruit pulp.
Coffees from Central America, particularly Guatemala and Honduras, often carry rum-adjacent notes, as do certain natural and anaerobic process coffees from Ethiopia and Brazil. The note is most reliably associated with natural or honey processing methods, where sugars from the coffee cherry ferment and absorb into the bean over time, producing complex, spirit-like qualities. Darker roast profiles can also coax out this character by caramelising the bean's inherent sugars into something closer to molasses or aged rum.
On a bag or cafe menu, look for descriptors such as molasses, dark sugar, brown sugar, barrel, or dark rum, as these often point to the same underlying flavour profile. Natural and anaerobic process coffees are typically the most reliable places to find this note, so checking the processing method listed on the packaging is a useful starting point. Brew methods that produce a fuller body, such as French press, Moka pot, or espresso, tend to emphasise this kind of rich, fermented sweetness more clearly than lighter filter methods.
