A speciality coffee flavour note across London.
Medicinal notes in speciality coffee present as a sharp, antiseptic quality reminiscent of TCP, iodine, or certain pharmaceutical syrups, occasionally accompanied by a phenolic or woody bitterness. The sensation tends to sit at the back of the palate and can linger into the finish. It most commonly arises from phenolic compounds, particularly guaiacol and related molecules, which can develop during fermentation, as a by-product of certain processing conditions, or through interactions between bean chemistry and roast development.
Coffees from Indonesia, particularly those processed using the wet-hulled or giling basah method, typically show medicinal or phenolic characteristics more frequently than those from other regions. Robusta varieties often carry stronger medicinal tendencies than Arabica, and natural or anaerobic-processed coffees that have undergone extended or imprecise fermentation can sometimes express similar notes. Certain Ethiopian naturals and some aged or long-rested green coffees may also develop this quality, depending on storage and processing conditions.
On a bag or menu, look for descriptors such as earthy, phenolic, tobacco, or woody alongside origin notes that point to Indonesia or natural processing methods, as these are reliable indicators that medicinal qualities may be present. Brew methods that concentrate the cup, such as espresso or a stovetop moka pot, tend to amplify these characteristics, while filter methods like a Chemex or V60 may soften them slightly. Those new to this note may find it easier to approach in a blend where it is balanced by brighter or sweeter components.
