Roasting
From green bean to first crack — understand roast levels, the chemistry of the Maillard reaction, home roasting, and how to keep roasted coffee fresh.
Coffee Freshness and Storage: The 7–21 Day Sweet Spot
Why roasted coffee is a fresh product — degassing, the 7–21 day peak window, why light roasts lose their florals fastest, and how to store beans (and when freezing actually makes sense).
Home Roasting Basics: Reading a Roast by Sight, Sound, and Smell
How to roast coffee at home with simple equipment — what green beans look, sound, and smell like at every stage, from yellowing through first crack to your target roast level, plus the gear that actually works.
The Chemistry of Roasting: Maillard, Caramelization, and the Acids
The chemical reactions that turn green coffee into brown — the Maillard reaction, Strecker degradation, caramelization, and pyrolysis — plus how citric, malic, acetic, quinic, and chlorogenic acids rise and fall with heat.
Light vs. Medium vs. Dark Roast: What the Labels Actually Mean
What roast levels really tell you (and what they don't) — the development milestones behind light, medium, and dark labels, how flavor, caffeine, and brewability change along the way, and why no two roasters' "medium" means the same thing.
The Coffee Roasting Process: From Green Bean to Golden Cup
The complete journey of a coffee roast — drying, the Maillard phase, first crack at ~196°C, the development window, second crack at ~224°C — and how roasters use heat, airflow, and time to turn a grassy green seed into coffee.
