Peat coffee in London

1 speciality roast from 1 London roaster feature peat notes.

Peat in speciality coffee presents as a deep, earthy smokiness with a dry, mineral quality that can recall damp soil, charred wood, or the distinctive character of Scotch whisky. It sits at the heavier end of the flavour spectrum and is rarely sweet, often accompanied by low acidity and a lingering, almost savoury finish. This note tends to emerge from darker roast profiles, certain natural or anaerobic processing methods, or from beans with naturally high levels of phenolic compounds that amplify earthy, smoky qualities.

Peat in coffee carries an earthy, smoky depth — think damp soil and dark woodland after rain, with a weight that lingers on the palate long after the cup is empty. It is a rare note in speciality coffee, found here in a Brazilian roast from Ovenbird, one of London's more quietly distinctive roasters. Brazil's dense, naturally processed beans lend themselves to this kind of heavy, grounded character, where fermentation and drying amplify the coffee's most primal, elemental qualities.

How peat notes develop

Peaty notes are typically associated with coffees from Sumatra and other Indonesian islands, where wet-hulling, a processing method known locally as Giling Basah, produces a distinctive earthiness not commonly found in other origins. Ethiopian coffees processed using natural or anaerobic methods can also occasionally show a peaty edge, particularly when grown at lower altitudes or processed in conditions that encourage fermentation. Robusta-influenced blends and coffees from parts of Papua New Guinea are also often noted for earthy, peaty characteristics linked to both processing conditions and local soil profiles.

What to look for

On a bag or menu, peat is sometimes described directly, though you may more often see it signposted by terms such as "earthy", "smoky", "tobacco", "forest floor", or "herbal". Single-origin Sumatran coffees and those labelled as wet-hulled or Giling Basah are reliable places to start. Brew methods that produce full-bodied, immersive extraction, such as French press or Moka pot, tend to emphasise this quality, as they allow the heavier, more resinous compounds in the coffee to come through clearly.
