Tool
Pour-over planner
Dose, ratio, bloom and however many pours you want — with the cumulative weights to stop at, because that is what you actually read off the scale, and what each choice changes in the cup.
Total water
240 g
Bloom to 30 g, then pour to each target below. These are cumulative scale readings, not the size of each pour.
- Bloom30 g
- Pour 1(add 70 g)100 g
- Pour 2(add 70 g)170 g
- Pour 3(add 70 g)240 g
On v60 or another cone
A cone with one large hole puts very little restriction on the flow, so the coffee bed and your pouring decide the brew time.
Sensitive to how you pour. More, smaller pours add agitation and slow the brew; a single steady pour is gentler and faster.
What the structure changes
The bloom wets the grounds and lets carbon dioxide escape, so the pours that follow soak in evenly instead of running around gas pockets. 3 pours add agitation and keep water in contact for longer than a single pour would, which extracts a little more. If the cup is sour or bitter, change the grind first; the pour structure is the finer adjustment.
How this was worked out
Total water = dose × ratio
15 × 16 = 240 g
Bloom = dose × bloom multiple
15 × 2 = 30 g
Each pour = water after the bloom ÷ number of pours
210 ÷ 3 = 70 g
Targets are shown cumulatively and the last one lands exactly on the total, so rounding never leaves the brew a gram short.
Exact arithmetic on your numbers
What to do with the result
- You want a starting recipe to plan from: V60: a starting recipe and its range
- The brew is made and you want to change the next one: Dialling in filter coffee: the workflow
- The drawdown stalls or the cup tastes wrong: Make my coffee better: pour-over
- You want to know what the brew time is telling you: Dialling in filter coffee: brew time is a reading
How it works
Total water is the dose multiplied by the ratio. The bloom is the dose multiplied by whatever bloom multiple you choose. What is left is divided between the number of pours you asked for, and each pour is then shown as a cumulative total, because a scale shows a running weight rather than the size of the pour you are currently making.
What the inputs mean
- Bloom multiple
- How much bloom water to use, as a multiple of the dose. Two to three times the dose is a common choice; more is used for very fresh coffee that expands a lot.
- Number of pours
- How many times you add water after the bloom. Fewer, larger pours are gentler; more, smaller pours add agitation and extend contact time.
- Cumulative target
- The reading to stop each pour at, counting from zero at the start of the brew — not the weight of that individual pour.
Worked examples
A classic three-pour V60
- Dose 15 g
- Ratio 1:16
- Bloom 2× dose
- 3 pours
Result: 240 g total. Bloom to 30 g, then pours to 100 g, 170 g and 240 g.
A larger single-pour brew
- Dose 30 g
- Ratio 1:16.7
- Bloom 3× dose
- 1 pour
Result: 501 g total. Bloom to 90 g, then one continuous pour to 501 g.
The same V60 with your own timings
- Dose 15 g
- Ratio 1:16
- Bloom 2× dose
- 3 pours
- Bloom time 40 s
- 30 s between pours
Result: Bloom to 30 g at 0:00, then pour to 100 g at 0:40, 170 g at 1:10 and 240 g at 1:40.
The clock is built from the timings entered. It is not a recommendation of them.
Common mistakes
Reading each target as the size of that pour
These are cumulative. If your scale reads 150 g and the next target is 250 g, you are adding 100 g.
Blooming to a fixed time regardless of the coffee
The bloom is carbon dioxide leaving. Very fresh coffee needs longer; older coffee barely rises at all.
Adding more pours to fix a fast brew
More pours extend contact time and add agitation, which helps a little. Grind is the bigger lever.
What the result does not mean
- There is no universally ideal pour schedule. This computes the structure you chose; it does not claim that structure is correct.
- A pour schedule cannot compensate for a grind that is far off.
What this does not account for
- Divides the post-bloom water evenly between pours. Plenty of good recipes do not, and you can enter a different structure by changing the number of pours.
- Does not choose how long to leave between pours, because that depends on your grind, your brewer and how fast the bed drains. If you enter your own bloom time and interval it shows when each step starts; it does not say when the brew will finish.
- The brewer you choose changes the explanation and not the numbers. A ratio asks for the same water in any brewer.
