V60 pour targets

Coffee 15 g · Input water 240 g · 1:16

Bloom · 0:00–0:30 · Add 30 g → Scale total 30 g
First pour · 0:30–1:15 · Add 90 g → Scale total 120 g
Second pour · 1:15–2:20 · Add 120 g → Scale total 240 g
Drawdown · 2:20–2:50

Do not tare between pours. Times are the 15 g / 240 g recipe's starting schedule; larger batches may drain differently.

Pour weights and timer handoff

At 1:16, 240 g input water needs 15 g coffee: bloom 30 g, then reach 120 g total and 240 g total. For 320 g water use 20 g coffee: bloom 40 g, reach 160 g, then 320 g. The targets above show both added water and the cumulative scale reading. Do not tare between pours. The timer link carries the selected water amount and ratio; it keeps the source recipe's 30 + 45 + 65 + 30 = 170 seconds. Larger batches may drain differently. These are input water weights; the filtered beverage weighs less. Save the public recipe card or log your actual result in the private journal.

Should I change ratio or grind first?

Treat sour or bitter taste as a clue, not proof of extraction. Check dose, water, roast and flow, change one variable at a time, then compare with your previous cup.

Do I need a scale to use a coffee ratio?

A scale is the most repeatable option. The calculator gives a gram target, while spoon or cup measurements are only rough approximations and vary with the coffee.
