What is third wave coffee?

Third wave coffee is a movement born in the early 2000s in the United States that treats coffee as an agricultural product of origin, much like fine wine or craft chocolate. Its hallmarks are farm-level traceability, lighter roasts that let terroir speak, precise brewing methods and a professionalised barista craft.

The phrase 'third wave coffee' was popularised in 2002 by American roaster Trish Rothgeb (also cited as Trish R. Skeie) in an article for the SCAA Roasters Guild. She described a new generation of roasters for whom every coffee is a singular product, defined by its origin, variety, altitude, processing and roast profile — not by an anonymous blend. The three-wave framing is retrospective. The first wave (late 19th-20th century) stands for the mass domestication of coffee — soluble coffees, big-brand blends, filter coffee as daily drink. The second wave (roughly 1970-2000, symbolised by Starbucks founded in 1971) brought espresso to the US, the café as a place, and early personalisation. The third wave added the agricultural, sensory and artisanal dimension.

The technical markers are clear. Roasts are lighter than in the Italian tradition (Agtron ~55-75, between cinnamon and city), preserving the volatile aromatic compounds and revealing acidity, florals and the fruity notes typical of high-altitude Arabicas. Brewing leans on manual filter — V60, Chemex, Kalita Wave, Aeropress — usually served as single origin rather than blend. Espresso is still present but pulled shorter and on lighter profiles than in Italy. Traceability is effectively mandatory: the bag carries the farm or cooperative name, variety, processing, altitude, roast date and tasting notes. The most-cited US roasters are Intelligentsia (Chicago, 1995), Counter Culture (Durham, 1995), Stumptown (Portland, 1999), and later La Colombe and Blue Bottle (2002). In Northern Europe, Tim Wendelboe in Oslo (founded 2007, 2004 WBC champion) and La Cabra in Aarhus have become recurring reference points in professional literature.

Third wave also reshaped the barista profession (SCA certifications, World Barista Championship, brewing-bar extraction skills) and paved the way for what some now call the fourth wave — open science, processing experimentation (co-ferments, anaerobic, carbonic maceration) and the spread of TDS meters and refractometers. One quiet statistical fact: third wave still represents only about 5-10 % of the global coffee market in 2024 (SCA and NCA estimates), yet it sets the technical standards that the industrial second wave is slowly absorbing — single origin on supermarket shelves, roast dates, traceability.

In Belgium, third wave settled during the 2010s, first in Brussels (Flagey, Saint-Gilles, Ixelles) and then in Ghent, Antwerp and Liège. It coexists with a robust second wave — chains, traditional filter coffee served with a speculoos or a cuberdon — which still dominates by volume but is losing ground among drinkers under 40.
