Yesterday's roast into the 1800's manual grinder. You can tell what kind of roast by how it grinds by hand, very similar to how you have a better feel of the road and your vehicle's performance with manual shifting of a transmission. Lighter roasts grind more and have more resistance (more caffeine!). The darker the toast, the easier they see to grind. This one is slightly past a medium, so will taste the roast more than the beans. I like it a little lighter, but my fault for roasting in the dark. Minimal chaff using the heat gun, that might actually just be remnants from the last grind. #coffee
