COFFEE ROASTING BEST PRACTICES by Scoth Rao
Coffee Roasting: Best Practices is the culmination of Scott's 25 years of roasting and consulting. It's the most advanced guide ever written about expert-level coffee roasting. There is little overlap with The Coffee Roaster's Companion, which focused on the basics of roasting and different roasting machines. This amazing book focuses solely on advanced techniques to craft and control roast curves, with numerous pages devoted to strategies to avoid "ROR" crashes and flicks, baked coffee, unnecessary roasty-ness, and other roast defects.
This book sets the standard for third-wave coffee roasting methodology.
