Well, in my case, not too local. I never miss a chance to visit and hang with the best of the best coffee roasters when I travel, whether it is coffee related or not. In some cases, facilities offer public tours, some don't. Do your homework first. Here's who I've visited this year:
Groundworks Coffee - Los Angeles, CA
Wow. Went to their retail shop first and had some AMAZING cups pulled from a Clover machine. Got to spend a good deal of time with the owner and their roasting facility. Immaculate. A great set up, very good coffee and fantastic employees to boot. Superior espresso shots.
Intelligensia Coffee - Chicago, Ill
Super cool. A great tour with the roasters, because the rest of the staff was attending the SCAA convention. The roasting facility offers public tours on the weekends. Get your geek on and get over there. Clover shots and some really nice tea too! Vintage roasters, top flight staff and great tips for us while we were in Chicago. Don’t miss it.
Gilles Coffee - Brooklyn, NY
I’m not sure if you can top over 100 years in the business. But that is what Gilles is all about. The team, the facility are some of the very best in the business. And a real impressive array of top flight coffees.
Graffeo Roasting Company - Beverly Hills, CA
Simply a great place to buy freshly roasted coffee in Los Angeles. They use a fluid bed roaster which I got to see in operation. Very clean and very basic. The coffee is very good. They do not sell coffee by the cup, you buy your bags in the store. Their one and only blend is a mélange of beans from Colombia, Costa Rica and New Guinea. If you are in LA and don’t pick up a pound, you’ve missed something very special.
