1662: Rousting Granny
Coffee Roasting Science, Light vs Dark Roast, Gigawatt Coffee
Producers and coffee roasters provide technical insights into the differences between light and dark roast coffee, noting that light roasts are denser and contain more caffeine by volume. The "knock box" used in espresso making is more effective with dark roasts because the beans are more brittle and carbonized. Gigawatt Coffee and other listener-owned businesses are mentioned as part of the show's "plug" system for donors.
