Episode notes
Caffeine and Roasting
- Roasting coffee can potentially destroy caffeine, but it also creates new compounds.
- Some new compounds are soluble, others are less so, impacting the brewing process.
Kinetic Brewing
- Coffee brewing isn't about extracting everything, it's a kinetic process.
- Brewing is stopped at a certain point, unlike equilibrium studies.
Roast Level and Extraction
- Darker roasts mean more porous beans, theoretically increasing extraction efficiency.
- This competes with caffeine sublimation during roasting.
