I'm in California to teach a roasting course and host a cupping. But in the meantime here's a little video from my trip last week to Portland with Sarah Dooley. We were putting on a cupping of Ethiopian coffees for the local specialty coffee roasters. Jeremy Adams of Cellar Door Coffee Roasters was kind enough to let us use his space. After the cupping he showed us his new baby, a Diedrich IR-12 roaster. To cut down on smoke without installing an expensive and carbon-hungry afterburner, Jeremy installed this cool scrubbing system instead.
Check it out... the videos a little shaky, but if you stick around till I get my camera in the right spot, you can see the super-fine particulate mist he's talking about.
