Definitions, ratios and protocols behind this recipe.
- V60 Hario's conical brewer is the most copied design in modern coffee, and for good reason: a 60° cone, deep ribs, and one big hole add up to a brewer that doesn't restrict flow at all. The grounds are what hold the water back, not the device. That makes the grind and your pour the only real variables.
- 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.
