Pour-Over Coffee Ratios: The Recipe for Every Dripper
The standard pour-over coffee ratio is 1:16 by weight — 15g of coffee for a 240g cup, or 60g of coffee per liter of water. V60 brewers often run slightly stronger at 1:15; Chemex and flat-bottomed drippers like the Kalita Wave tolerate the same range; Origami sits squarely at 1:16. Use those as starting points, then adjust by taste.
That's the whole recipe sheet. The rest of this article is brewer-specific guidance for when the default doesn't quite land.
The Recipe Sheet
For a single 250g cup brewed by hand:
- Hario V60: 1:15 to 1:16 — 15.5–16.5g coffee
- Kalita Wave 155: 1:16 — 15.5g coffee
- Chemex (3-cup): 1:15 to 1:17 — 14.5–16.5g coffee
- Origami: 1:15 to 1:16 — 15.5–16.5g coffee
- Melitta / cone drip: 1:16 to 1:17 — 14.5–15.5g coffee
- Flat-bottom (BeeHouse, Bonavita): 1:16 to 1:17
For a larger batch (500g brewed weight):
- Multiply all coffee weights by two. A 1:16 V60 at 500g = 30g of coffee.
For full method walkthroughs, see the pour-over coffee guide and the focused V60 brewing guide and Chemex brewing guide.
Why V60 Runs Slightly Stronger
The Hario V60 has a steep 60-degree cone, a single large drain hole, and spiraled internal ribs that promote fast flow. Brews finish quickly — typically 2:30 to 3:30 for a single cup. That faster contact time means slightly less extraction efficiency, which is why V60 recipes often push ratio toward the stronger end (1:15) to compensate.
Translation: a 1:15 V60 hits a similar strength-and-extraction balance as a 1:16 flat-bottom, because the flat-bottom has longer contact time at the same ratio.
Why Chemex Behaves Differently
The Chemex bonded filter is roughly 30% thicker than a typical paper filter. That changes two things: flow rate is slower, and more oils and fine sediment are caught in the paper. The cup runs clean — almost tea-like — and the slower flow gives more contact time.
You can run Chemex at the same ratios as V60 (1:15 to 1:17). At 1:15 it gets bigger and more concentrated; at 1:17 it gets clean and almost delicate. The brewer's strength is delivering a clean cup, so most Chemex drinkers settle around 1:16.
Why Kalita and Origami Are Forgiving
The Kalita Wave's flat bottom and three small drain holes regulate flow more than the V60 does. The Origami's faceted walls allow you to use either a Wave-style flat-bottom filter or a V60 cone filter, depending on what flow you want.
Both forgive technique imprecision better than the V60, which is why competition brewers often pick them. Standard ratio sits at 1:16 and works well across light, medium, and medium-dark roasts.
Adjusting Ratio by Roast Level
This is where most pour-over advice oversimplifies. Roast level affects density and solubility, both of which interact with ratio.
- Light roast: Less soluble, harder to extract. Stay at 1:15 to 1:16 to give yourself enough coffee mass to extract from. A 1:18 ratio on a Nordic-style light roast will taste thin and grassy.
- Medium roast: 1:16 is the safe default. Most specialty subscription coffees fall here.
- Medium-dark to dark roast: More soluble, extracts faster. 1:16 to 1:17 prevents the cup from going muddy or bitter. Some dark roasts are happier at 1:17 or 1:18.
If you don't know your roast level, ask the roaster. Most quality roasters publish it. If you can't tell, brew at 1:16 and adjust from the result.
Adjusting Ratio by Brew Size
Bigger brews extract slightly more efficiently than smaller ones, because the coffee bed sits deeper and water dwell time is longer.
- Single cup (15g): May benefit from 1:15 to stay in the strength sweet spot.
- Double cup (25–30g): 1:16 typically lands right.
- Full Chemex (45–60g): 1:16 to 1:17 is the working range; going stronger at this scale can over-extract.
This is one of the reasons "scale up the recipe linearly" rarely works perfectly. Ratios drift by a half-point or so as batch size changes.
Ratio Is Not the Whole Recipe
Pour-over depends on three variables working together: ratio, grind, and pour technique. Get one wrong and the others can't compensate.
- Grind size: Medium-fine for V60. Medium for Kalita Wave. Medium-coarse for Chemex. The right grind for your ratio is the one that finishes the brew in the target time — 2:30 to 3:30 for single cup pour-overs.
- Pour technique: A 30-second bloom (twice the coffee weight in water), then a controlled pour to total weight. Steady center-out pours, no flooding.
- Water temperature: 200°F (93°C) for most pour-overs. Drop to 195°F for very dark roasts; nudge toward 205°F for stubborn light roasts.
For the full method, see the pour-over coffee guide. The coffee-to-water ratio master guide is where the math gets unified across methods.
Common Mistakes
"My V60 always tastes thin." Either your ratio is too weak (try 1:15 instead of 1:17), your grind is too coarse, or you're under-extracting. Check ratio first because it's the easiest to fix.
"My Chemex tastes muddy or bitter." Likely over-extraction. Coarsen the grind first. If still bitter at the right grind, weaken the ratio to 1:17.
"My pour-over is inconsistent from day to day." Almost certainly a weight problem, not a ratio problem. Volumetric measurement is the single biggest source of cup-to-cup variation. Weigh in grams.
FAQ
What's the best pour-over ratio for a V60?
1:15 to 1:16 is the working range. Start at 15g of coffee to 240g of water for a single cup. Adjust to 1:15 if the brew tastes thin or 1:17 if it tastes harsh.
Is 1:15 too strong for pour-over?
Not for V60 — it's often the recipe's center. For flat-bottom and Chemex it produces a heavier, more concentrated cup that some drinkers prefer. Brew side by side at 1:15 and 1:16 once and you'll know which you want.
How much coffee for a full Chemex?
The classic 6-cup Chemex holds about 850g of water. At 1:16 that's 53g of coffee. At 1:17 it's 50g. Both are fine; 1:16 is the more common starting point.
Does pour-over ratio change for cold weather brewing?
No. Ratio stays constant; what changes is your final cup temperature, which is affected by ambient temperature, pre-warming the carafe, and how quickly you serve. Pre-warm the server with hot water before brewing if you're losing heat fast.
Why do baristas often weigh water as they pour?
Because pouring blind is unreliable. A scale lets you see exactly when you've hit each target weight (bloom, first pour, total), which is the difference between a recipe and an estimate. Most modern brew scales also include a built-in timer.
When the Recipe Lands and the Cup Still Misses
A Pinkies Out co-ferment from Lamppost Coffee — a recent Golden Bean World Series winner — opens completely differently in a V60 than in a Chemex, even at the same ratio. That's the kind of coffee Podium Coffee Club was built to ship: beans from US roasters who've placed at the major blind-judged competitions, sent within 24 hours of roasting, no marketing-flavored filler in the lineup.
Podium Gold starts at $24.50/month for a 300g bag — the cleanest entry point. Podium Platinum is $29.50/month for the more experimental picks. If you're shopping the category, our guide to the best coffee subscriptions maps the field.
