The "third wave of coffee" is a phrase used to describe a shift in how coffee is produced, roasted, brewed, and consumed — a movement that began in the late 1990s and transformed specialty coffee from a niche interest into a global phenomenon.
The First and Second Waves
To understand the third wave, you need the first two. The first wave of coffee was the 19th and early 20th century industrialisation of coffee — the moment it went from an artisanal product to a mass-produced commodity. Vacuum-packed tins, instant coffee, the percolator. Coffee became cheap, consistent, and not particularly good.
The second wave arrived in the 1960s–80s, led by companies like Peet's Coffee and Starbucks. It brought espresso-based drinks, dark roasts, and the café as a "third place" between home and work to the mass market. It made coffee experiential — a ritual, not just a beverage — and created the category of the specialty café.
The third wave reacted against the second wave's dominance of dark roasts and commodity beans by treating coffee the way wine is treated: as an agricultural product whose quality is traceable to specific farms, varietals, harvest years, and processing methods.
What the Third Wave Changed
- Traceability: Third wave roasters buy directly from specific farms or cooperatives, visiting producers and paying above-market prices. The bag tells you which farm the coffee came from, who grew it, how it was processed.
- Light roasting: Lighter roasts preserve the origin character of the bean rather than replacing it with roast flavour. This was controversial — many people trained on dark roasts find light roasts sour or thin at first.
- Brewing precision: Scales, thermometers, grind consistency, water mineral content — third wave coffee culture brought scientific precision to home and café brewing.
- Tasting notes: Specialty coffee uses wine-like descriptors — "jasmine, bergamot, blueberry" — to describe flavour. This can feel pretentious but reflects real differences in flavour between origins and processing methods.
The Criticism
Third wave coffee has attracted legitimate criticism: it can be expensive, exclusionary, and sometimes more performative than educational. Cafés that serve a single cup of pour-over in silence for €8 without explanation can make people feel judged rather than welcomed.
The best of the third wave rejects this attitude. Great specialty coffee should be accessible — explained clearly, priced fairly, and brewed with the goal of delighting the person drinking it, not impressing them.
