Calendario de floración y vertidos
Florece con 59.9 g de agua y espera ~45 s para que el café desgasifique. Luego realiza 3 vertidos iguales de 146.7 g cada uno, acumulando 500 g en total. Alternativa Tetsu Kasuya 4:6: divide el agua en un primer 40 % (200 g) para el dulzor y un último 60 % (300 g) para la fuerza.
Acerca de esta calculadora
A good pour-over is defined by its ratio, not its size. This scaler takes a brew ratio (1:N) and a target — how many cups you want — and works out the coffee dose and water weight that keep the same strength, then lays out a bloom-and-pour schedule so you know exactly when to add each pour. It also shows the Tetsu Kasuya 4:6 split as an alternative pouring style.
Cómo leer tus resultados
Pick a ratio: James Hoffmann's V60 uses about 1:16.7, which is a balanced starting point. Lower numbers (1:12–1:15) brew stronger; higher numbers (1:17–1:20) brew lighter. One "cup" here is 250 mL of water, so 2 cups = 500 g of water. The dose is computed from the ratio and the total water (dose = water ÷ N). The bloom is about twice the dose in water; the rest is split into equal main pours.
Cómo se calcula
Water target = cups × 250 mL. Dose = water ÷ ratio (so the 1:N ratio is preserved at any size). Bloom = about 2× the dose in water, rested ~45 s to let the grounds degas. The remaining water is divided into equal main pours that cumulate to the total. The Tetsu 4:6 alternative splits the same total water into a first 40% (controls sweetness/acidity) and a last 60% (controls strength).
Ejemplo práctico
A 30 g : 500 g recipe (1:16.7) scaled up to 4 cups (1000 g of water), with 3 main pours.
You need 60 g of coffee for 1000 g of water (same 1:16.7 ratio). Bloom with ~120 g (2× dose) for ~45 s, then three pours of ~293 g each up to 1000 g. The 4:6 split would be 400 g then 600 g.
Preguntas frecuentes
What ratio should I use?
About 1:16.7 (Hoffmann's V60) is a reliable, balanced starting point. Brew stronger with 1:14–1:15 or lighter with 1:17–1:18, then adjust by taste — the ratio sets strength, the grind and pour set extraction.
How big should the bloom be, and how long?
Pour roughly twice the dose in water (Barista Hustle suggests 2–3×) to wet all the grounds, then wait about 45 seconds for the carbon dioxide to escape. A good bloom makes the rest of the pour even.
What is the 4:6 method?
Tetsu Kasuya's 4:6 splits the total water into a first 40% and a last 60%. The first 40% (in one or two pours) dials sweetness vs acidity; the last 60% dials strength. It is an alternative to evenly spaced pours, not a different ratio.
Is 1 cup really 250 mL?
This calculator uses 250 mL of water per cup as a practical filter-coffee convention. A standard "metric cup" is 250 mL, while a US cup is ~237 mL — close enough that the ratio, not the cup definition, decides the taste.
