What Is the Best Pour-Over Coffee Ratio?
For your first pour over, weigh 20 g of coffee and 320 g of water. That is a 1:16 ratio, a useful place to start before trying a stronger 1:15 or lighter 1:17 brew.
Use the scale for both ingredients. A scoop changes weight with the coffee and grind, so it can make a familiar recipe surprisingly hard to repeat.
Start With a Practical Baseline Ratio
Try 20 grams of coffee and 320 grams of water. This 1:16 recipe is a starting point for brewers such as a V60, Kalita Wave or Chemex, as well as the options in our pour-over range. Adjust the batch to the capacity of your brewer.
- 20 g coffee + 300 g water (1:15) — a stronger starting recipe if you plan to add milk.
- 20 g coffee + 320 g water (1:16) — a balanced place to start.
- 20 g coffee + 340 g water (1:17) — a lighter starting recipe; adjust the grind if it tastes thin.
Make a few cups at the same ratio while you get used to pouring. If the same flavor problem keeps showing up, you will have a clearer idea of what to adjust.
Pour over ratio chart for 1–4 servings
The table allows about 250 grams of brewing water per serving. Choose the water amount that fits your mug; the finished drink will be smaller because the grounds retain some water.
| Approximate servings | Brewing water | Coffee at 1:15 | Coffee at 1:16 | Coffee at 1:17 |
|---|---|---|---|---|
| 1 | 250 g | 16.7 g | 15.6 g | 14.7 g |
| 2 | 500 g | 33.3 g | 31.3 g | 29.4 g |
| 3 | 750 g | 50.0 g | 46.9 g | 44.1 g |
| 4 | 1,000 g | 66.7 g | 62.5 g | 58.8 g |
For larger batches, check the capacity of both the dripper and the carafe. Split the recipe if the coffee bed or water level would be too high.
Calculate any batch in seconds
Divide water weight by the second number in your ratio:
Coffee needed = water ÷ ratio number
For 400 grams of water at 1:16, use 25 grams of coffee. If you have already weighed 18 grams of coffee, multiply by 16 to get 288 grams of water.
The bloom is part of that total. If you pour 50 grams for the bloom in a 400-gram recipe, there are 350 grams left to add. Rinsing water is separate and should be discarded before you weigh the brew.
If you prefer a reusable filter, the 400/600 ml glass pour-over brewer is an option. Choose the size for your usual serving, then keep the dose within the filter's capacity when using the ratio chart.
How Grind Size Affects Pour-Over Extraction
Ratio affects strength; grind size affects flow and extraction. A finer grind often slows the drawdown, but brew time alone does not tell you whether the coffee will taste good. Use the time and flavor together when deciding what to change.
- Harsh, drying, sharply bitter? One step coarser.
- Thin, sour, hollow through the middle? One step finer.
Make a small grind adjustment and keep the ratio the same so you can judge its effect.
How Water Temperature Works With Ratio and Grind
Water temperature also affects extraction. 90–96 °C (194–205 °F) is a useful starting range for filter coffee. Try the warmer end for light roasts and a little cooler for dark roasts, then adjust to taste.
An ordinary kettle can work. Let the water cool briefly after boiling, but remember that the temperature depends on the kettle, water volume and room conditions. Use a thermometer if you want to measure it, or consider a variable-temperature electric gooseneck kettle for easier repeatability.
- Light roasts — dense and slow to extract, so 94–96 °C (201–205 °F).
- Dark roasts — porous and quick to turn ashy, so 90–92 °C (194–198 °F) is kinder.
Keep temperature steady while adjusting grind and ratio. If the grounds are uneven, a burr grinder with suitable adjustments may make the recipe easier to control.
How to Bloom Pour-Over Coffee
The bloom wets the grounds and allows some trapped gas to escape before the main pour. Pour gently across the bed so you don't leave dry pockets.
For a 20 g dose, start the bloom with about 40 g of water and make sure the whole bed is wet. Wait 30–45 seconds before the main pour. If dry patches remain, adjust where you pour or add a little more bloom water, counting it toward the recipe total.
How Bean Freshness Changes the Brew
Coffee releases gas after roasting, and fresher beans may bloom more vigorously. The amount varies with the coffee, roast and storage, so use the bloom to check wetting rather than to judge freshness on its own.
Older beans may produce fewer bubbles and lose some aroma. Read more about how coffee changes after opening, and let the flavor guide any recipe adjustment.
- Violent bloom? Stretch it to 45 seconds and pour those first 40 g more gently.
- Flat bloom, dull cup? One step finer, or move from 1:17 to 1:16.
Buy a bag size that fits how often you brew. Seal it between uses and keep it somewhere cool, dry and out of direct light.
Pour-Over Pouring Technique: Stages vs. All at Once
After the bloom, pour the remaining water gently over the grounds. Two or three pours are easy to keep track of. A continuous pour works too, provided you can maintain a steady stream.
Pour gently enough to keep the bed reasonably even. Grounds left high on the filter wall can be a sign to reduce agitation on the next brew.
Common Pour-Over Mistakes and What They Taste Like
These habits can make a familiar recipe less consistent:
- Pouring too fast. Water outruns the grounds and the brew drains in under two minutes — weak and watery at a ratio that should have been strong.
- Pouring onto the filter wall. Some water slides down the paper past the coffee entirely, which thins the cup and strips the sweetness out of the middle.
- Scooping instead of weighing. The dose can vary, making it harder to compare brews.
- Dialing in once and forgetting. A bag set up in its first week usually wants a step finer by week three as it degasses.
Before changing the recipe, check that you weighed the intended dose and poured the intended amount of water.
How to Adjust Your Pour-Over by Taste
Record brew time, then taste the coffee. A consistent time is useful, but the recipe should still produce a cup you enjoy.
- Too intense? 1:15 → 1:16 → 1:17.
- Too weak? 1:17 → 1:16 → 1:15.
- Bitter and drying? Hold the ratio, grind coarser.
- Sour and hollow? Hold the ratio, grind finer.
What to Write Down While You Dial In
A few notes help you compare brews without relying on memory. If you brew by weight with a timer running, you already have most of the information you need:
- Dose and water weight, plus the ratio they come to.
- Grind setting, written as the number on your grinder rather than "medium".
- Water temperature, or the seconds you waited off the boil.
- Total time from first pour to last drip.
- One word for the cup: sweet, sour, bitter, thin, balanced.
Change one variable and record the result. Many digital coffee scales display weight and time together, which makes this easier. Once the coffee tastes balanced, keep that recipe as your starting point for the rest of the bag.
Frequently asked questions
What is the best coffee to water ratio for pour over?
Start between 1:15 and 1:17. At 1:16, use 20 g of coffee and 320 g of water. Try 1:15 for a stronger cup or 1:17 for a lighter one, then adjust for your coffee and brewer.
How many grams of coffee do I need for one cup of pour over?
For a single mug, try 15 to 20 g of coffee. At 1:16, that means 240 to 320 g of water. Use a dose that suits your dripper; very small batches may need a different grind or pouring approach.
Why does my pour over taste bitter?
A fine grind, excessive agitation or a long drawdown can contribute to bitterness, but roast level and water also matter. Try a slightly coarser grind while keeping the other variables steady, then compare the taste.
How long should a pour over take?
Many 20 g pour overs finish in roughly 2½–3½ minutes, including the bloom, but the brewer, filter and recipe can move that time considerably. Record it as a reference. A change from your usual time is more useful than hitting a particular number.
Do I need a gooseneck kettle for pour over?
You do not need one if your existing kettle pours slowly and accurately. A gooseneck spout makes it easier to control where the water lands, especially during the bloom and small pours.
A Repeatable Pour-Over Routine
For tomorrow's brew, keep these measurements handy:
- 20 g coffee, 320 g water at 1:16, brewed at 92–94 °C (198–201 °F).
- Bloom with 40 g for 30–45 seconds.
- Two or three gentle pours across the coffee bed.
- One variable per brew — ratio first, then grind, then temperature.
Save the recipe when you get a cup you like. With a new bag, start there and adjust from the taste.

A gooseneck kettle in 350 ml or 600 ml can help you place the water more accurately. A scale reading to 0.1 g with the timer on the same screen keeps dose, water and time easy to check. For storage between brews, an airtight canister with a one-way valve is one option for keeping beans sealed. Choose the tools that address a difficulty in your current routine.
