1 speciality roast from 1 London roaster feature low acidity notes.
Low acidity in speciality coffee presents as a smooth, round, and soft sensation on the palate, with little of the bright, citrus-like sharpness associated with high-acid coffees. The overall effect is often described as mellow or gentle, allowing heavier, sweeter, or earthier flavour characteristics to come forward without interference. Low acidity is typically the result of a combination of factors including high growing altitude being absent, darker roast profiles that break down chlorogenic acids, and processing methods such as natural or wet-hulled processing that alter the bean's chemical composition.
Low acidity coffee presents a smooth, mellow palate with gentle brightness—a refined alternative to sharper profiles. Assembly, our sole London roaster currently offering this characteristic, sources beans that naturally develop this rounded quality through their origin and processing methods, creating a coffee that settles warmly on the palate without the tangy notes typical of higher-acidity brews.

London roasters with the most approved coffees carrying low acidity notes.
Notes that most commonly appear alongside low acidity in the same roasts.
Coffees from lower-altitude growing regions such as Sumatra, Sulawesi, and other parts of Indonesia are typically associated with low acidity, partly due to the elevation and partly due to the wet-hulled processing method commonly used there. Brazilian coffees, which are often grown at relatively modest altitudes and processed using natural or pulped natural methods, also tend to exhibit a softer, less acidic profile. Robusta-influenced blends and darker-roasted single origins from various origins can further reduce perceived acidity regardless of where the coffee was grown.
On a bag or cafe menu, look for tasting notes that include words such as chocolate, earth, cedar, tobacco, nuts, or heavy body, as these descriptors often accompany low-acidity profiles. Origin labels indicating Sumatra, Brazil, or similar regions, or roast descriptors such as medium-dark or dark, are also useful indicators. Brew methods that use immersion and produce a fuller body, such as French press or AeroPress with a longer steep, tend to complement and highlight the smooth, low-acid character of these coffees particularly well.
