San Francisco's Sightglass came in first, followed by Ecco from Santa Rosa, San Jose's Barefoot and San Francisco's Four Barrel.
Blogger Matt Honan, who organized the blind taste test, says San Francisco has some of the best specialty coffees in the world right now.
"It doesn't tend to be as dark of a roast as a lot of places you're getting roast and a lot of San Francisco roasters are really honing in on specific farms, not even a specific region," Honan said.
Sightglass' winning coffee came out of Siberia Estate from El Salvador.
Hearing the owner describe his coffee is like hearing someone describes a fine wine.
"It's just really round, a lot of body; a lot of chocolaty notes, crisp apple sweetness," Sightglass co-owner Justin Morrison said.
What do you do once you get those coffee beans home? Brew it like your grandparents did with a slow drip for the best flavor.
