Our last guest for RoastID was Joe Marrocco, management executive for List + Beisler, owner of Hodges Bend MN, and former educator at Mill City Roasters. For this final round we branched out to a plethora of large-scale topics challenging and the highly notorious topic of blends in the coffee roasting industry. We discussed how roast profiles can be created specifically for developing a blend rather than a single-origin coffee, how different flavors interact when coming together in a blend, and the impact of varying green coffee characteristics (variety, density, moisture content, origin, etc.) on developing roast profiles, with a heightened focus on processing methods.
