The cultural and commercial movement that re-positioned coffee from a commodity drink into a craft product, beginning roughly in the late 1990s and crystallizing through the 2000s. The name borrows from beer and food culture, where each "wave" describes a similar shift toward provenance and quality.
The three waves, in order
First wave (early-mid 20th century). Mass-market instant and pre-ground coffee. Maxwell House, Folgers, Nescafé. Coffee as fuel: cheap, ubiquitous, indistinct.
Second wave (1970s–1990s). Espresso-based café culture. Starbucks, Peet's, Illy. Coffee as experience: lattes, dark roasts, Italian-style espresso served everywhere. Origin still mostly invisible to the drinker.
Third wave (late 1990s onward). Coffee as ingredient. Single origins printed on the bag. Roast date instead of expiry date. Light to medium roasts that let the bean speak. Manual brewing — V60, AeroPress, Chemex — back from extinction. Direct trade and transparency about farms and prices. Roasters like Stumptown, Intelligentsia, Counter Culture, Square Mile, and Tim Wendelboe defined the early aesthetic.
What the term actually meant
A shift in where the value lived. In second-wave espresso, the barista's milk-steaming technique was the craft; the bean was a generic input. In third-wave brewing, the bean became the craft — the origin, variety, processing, and roast curve mattered more than the cafe's milk technique. Pour-over, manual brewers, and lighter roasts were the natural consequence: they're the formats that let the bean lead.
The term is now somewhat dated — many in the industry just say "specialty" — but it remains the clearest historical label for the moment when filter coffee became a precise discipline rather than a generic product.
