It's a somewhat opinionated guide to roasted coffee product development. Five chapters. Starts with having a plan for your product line, moves to sample roasting and cupping practices (sourcing coffees that align with your plan), then figuring out how to roast those coffees, a chapter on blending, and ending on finished product quality testing.
Once I've created the images, put those in place, and gotten through at least a couple rounds of editing I'll be contacting the people who agreed to do technical review for the print book and find out if they're willing to take a look at this one as well.
