Have you ever heard of Dunn Meters, or wonder what happens to coffee roasters Before Cropster (BC). Or any of the following: What Craig Charity prefers to wear?

Are you a Roast and Taste repeat kind of roaster. Who is in charge of what at Legado. What changes when you use Cropster. How the Mississippi influences your roast? What makes coffee great. And echo mumblings by Craig Charity

We chat about a green bean storage experiment he did recently, hear about how he got into coffee, talk a little bit about sustainability and quality control certification.   Sorry about the noise quality we tried to record in a quiet room and had a strange buzzing noise through out, which we tried to remove but it created a muted echo on the voices.
