Most coffeehouses use one roaster for their beans. An exception used to be Seattle Coffee Works, but earlier this year last year it began roasting only its own coffee and stopped carrying the others.

Now Tougo Coffee -- at 1410 18th Avenue in the Central District and at 2113 Westlake Avenue -- is adding roaster -- and city -- variety, with coffee drinks and beans from Stumptown, Intelligentsia, Ritual Coffee and Ecco (owned by Intelligentsia). Tougo's former roaster, Caffe Vita, is not part of the new mix.

Stumptown is headquartered in Portland, but has a roastery in Seattle. The other coffees -- Intelligentsia, Ritual Coffee and Ecco -- come from three different parts of California.

Tougo owner Brian Wells (pictured) said he wants to "introduce coffees from different cultures and different cities to the Seattle palette. I want to give Seattle an opportunity to taste different roasters and have those roasters be able to tell their stories from different source trips (to coffee-growing regions)."

Customers will be able to choose from four espresso blends each day -- and on weekends, "single-origin" espressos that have the flavor of just one country. Wells also is adding brewing methods and is pictured here with (left to right) a Melitta drip brewer, a French press, a siphon or vacuum pot and a Chemex coffee maker.
