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.
- Processing Coffee grows as a cherry. The bean you brew is the seed. Processing is everything that happens between picking the cherry and getting a dry green bean ready to ship — and it's the second-biggest flavor decision after origin. Two coffees from the same farm processed differently will taste like two coffees.
