Advanced Roasting Fun

Here's a video I took this afternoon... a sunny August afternoon in Northern California. This is day two of a three day Advanced Roasting Techniques class I am teaching at Boot Coffee.

There are three groups going here, one on a 1 pound San Franciscan roaster (the red one), one on a 5 kilo Probat from 1948 (the black one), and one on a three barrel Gothot sample roaster (the silver one). Each team has a different task to complete, using green coffee from the stock of dozens of different coffees Boot Coffee has in its lab.

Tomorrow morning we are going to cup the results (27 coffees!) and have each team interpret and defend the results of their experiments.
