Home roasting is closer to brewing than most people expect — green beans, a heat source, and a good exhaust fan. Here's what actually works.
I kept a mason jar going in the fridge door for a whole summer, topping it up. Cold brew has no kill step, which makes it a sanitation job first and a ratio job second.
Two years of blaming the beans for something the kettle was doing. The band the NCA actually names, where the heat goes before the grounds see it, and why altitude reverses the advice.
Roast the parts separately, then combine by weight. A base, an accent, and a seasoning — and one honest tasting order that catches you out when the blend isn't working.
A scoop and the marks on the carafe feel like measuring, and neither one is. Converting the Golden Ratio into grams, and why weak coffee and sour coffee need opposite fixes.
Color and the clock can't tell you how far a roast went. A kitchen scale can. The weight-loss percentage, what the ranges mean, and the six-field log built around it.
Your coffee is 98% water. Here's why the tap can flatten a good roast, the mineral range worth aiming for, and how to fix your water for a few dollars.
What green beans actually cost, what equipment you need, and when to trust your nose over the clock.
What actually defines a roast level, and why medium is the easiest to hit consistently at home.
Oxygen, light, heat, and moisture — and the one habit that matters more than any container.
Why grind consistency is a bigger upgrade than almost anything else in your setup.
Why constant airflow roasts more evenly than a pan, and what to modify first.
Where hobbyists actually buy green coffee, what origin and process notes mean at the pan-and-popper scale, and how to keep a few pounds of green stock fresh for months.
A stripped-down side-by-side tasting routine — same dose, same water, one timer — that turns each roast batch into feedback instead of a guess.
