The third wave of coffee is a movement to produce high-quality coffee, and consider coffee as an artisanal foodstuff, like wine, rather than a commodity. This involves improvements at all stages of production, from improving coffee plant growing, harvesting, and processing, to stronger relationships between coffee growers, traders, and roasters, to higher quality and fresh roasting, at times called "microroasting" (by analogy with microbrew beer), to skilled brewing.
Third wave coffee aspires to the highest form of culinary appreciation of coffee, so that one may appreciate subtleties of flavor, varietal, and growing region – similar to other complex consumable plant-derived products such as wine, tea, and chocolate. Distinctive features of third wave coffee include direct trade coffee, high-quality beans (see specialty coffee for scale), single-origin coffee (as opposed to blends), lighter roasts, and latte art. It also includes revivals of alternative methods of coffee preparation, such as vacuum coffee and pour-over brewing devices such as the Chemex and Hario V60.
The term "Third Wave" was coined in 2002, and refers chiefly to the American phenomenon, particularly from the 1990s and continuing today, but with some effects from prior decades. Similar movements exist in Canada, Australia, New Zealand, and Scandinavia. More broadly, third wave coffee can be seen as part of the specialty coffee movement.
Antecedents of third wave coffee include Peet's Coffee & Tea of Berkeley, California, which in the late 1960s began artisanal sourcing, roasting, and blending, and the Seattle coffee scene of the 1970s, 80s, and 90s, which saw the birth of artisanal American espresso bars, some of which evolved into nationwide chains, notably Starbucks, which are retrospectively titled "Second Wave". (Peet's primarily retails beans for home brewing, features dark roasts, and did not serve espresso until 1984.) These in turn were predated by Italian American espresso bars, primarily serving immigrant communities, and 19th century "First Wave" coffee importers.
