Pour-Over
Tetsu Kasuya’s 4:6 method · 1:14 ratio
The method we reach for first with Amara Ritual. Kasuya’s 4:6 splits the water into two halves that do different jobs: the first 40% sets how sweet or how bright the cup lands, the last 60% sets how strong it is. We ease that last 60% into fewer, larger pours for a softer cup.
Amara sits two degrees cooler. It is the darker of the two, and the lower temperature keeps the black honey sweetness from tipping into bitterness.

Weigh and grind
20 g of coffee to 280 g of water is the 1:14 ratio at a comfortable single-cup size — scale both figures together for more. Grind medium-coarse, like coarse sand, and grind it now rather than earlier.

Rinse, then the first pour
Rinse the filter with hot water and discard it. Add the grounds and level them, then pour 56 g and wait 45 seconds. The bed will swell and release gas — that is how you know the coffee is fresh. In the 4:6 method this bloom is not separate from the recipe; it is the first half of the 40%.

Second pour — to 112 g
Another 56 g, bringing the total to 112 g, which is the 40%. Two even pours give a balanced cup; a smaller first and a larger second leans sweeter.

4
The last 60% — strength
The remaining 168 g in two larger pours rather than four small ones, each as the bed draws down. Fewer and larger is what softens the cup.

Finish
Total brew time 2:30–3:00. Draining much faster means the grind is too coarse; much slower, too fine. Swirl the carafe before pouring.
Quantities above are a worked example of the 1:14 ratio at 20 g. The ratio is the instruction; the grams are just one convenient size.
