Definitions, ratios and protocols behind this recipe.
- Chemex The Chemex is mostly known for its hourglass silhouette, but its real signature is the paper. Chemex bonded filters are 20–30% thicker than standard pour-over papers — they trap more oils, more fines, and slow flow noticeably. The brewer is a vessel; the filter does the work.
- Origin Where the coffee grew shapes the cup more than almost anything else. Soil, altitude, climate, and varietal interact for the years the tree spends in the ground. Once the cherry is picked, the rest of the chain (processing, roast, brew) only modifies what's already there. You can't put fruit into a coffee that wasn't grown for it.
