How to Calculate your Batch Size based on BTUs (Scott Rao of Prodigal Coffee)

This is part 2/4 in a video series on coffee roasting batch sizes. These interviews were research for an article I wrote for the September/October 2023 issue of Roast Magazine about batch size. This second video is an interview with Scott Rao - roaster, writer, consultant, educator. Scott is a well-established voice in the coffee industry, has a wealth of experience on many machines, and is behind many often-cited frameworks and concepts within the roasting space. In this interview, Scott shares key batch size insights, including a formula for calculating maximum batch size based on a machine's BTU, tips for between batch protocol (BBP) for varying batch sizes, differences between traditional drum roasters (Probat, Geisen, etc) and air roasters (Loring, IMF, etc), and more.
