How to Make Pour Over Coffee (Ratio, Grind and Technique)

Pouring hot water over coffee grounds in a Kalita Wave dripper

Pour over looks fussy, with its gooseneck kettles and scales, but the method itself is simple: hot water, poured slowly over ground coffee in a filter. What makes it worth the attention is control. Every variable that shapes the cup is in your hands, which means once you understand the handful that matter, you can brew coffee as good as any café’s at your kitchen counter.

What Is Pour Over Coffee?

Pour over, defined

Pour over is a manual brewing method where hot water is poured by hand over ground coffee in a paper filter, and the coffee drips through into a cup or carafe. Because you control the pour, the result is clean, bright and full of the bean’s own flavor.

  1. Ratio: about 1 gram of coffee to 16 grams of water.
  2. Grind: medium-fine, like table salt.
  3. Water: 200 to 205°F (93 to 96°C), just off the boil.
  4. Time: about 3 to 4 minutes from first pour to last drip.

Pour Over Coffee Ratio

The ratio is the single biggest decision in a pour over. Most specialty cafés work between 1:15 and 1:17, meaning 15 to 17 grams of water for every gram of coffee. Start at 1:16 and move from there once you know whether you want the cup stronger or lighter.

At 1:16, a single 10 oz cup (300 g of water) takes about 19 g of coffee. Two cups (600 g) take about 38 g, and a full carafe (900 g) about 56 g. Weighing beats scooping every time, because a scoop of coffee can vary by several grams depending on roast and grind; our coffee-to-water ratio guide explains the numbers behind it.

If you would rather have the numbers on your counter, our printable Coffee-to-Water Ratio Guide gives the proven ratio, grind and water temperature for pour over and seven other brew methods, with a one-page chart for the kitchen.

What You Need

You can make pour over with a dripper, a filter and a kettle. Three more tools make it consistent, and they are the difference between a good cup some days and a good cup every day.

A dripper and paper filters

The cone or flat-bottomed brewer that holds the coffee. Paper filters give the cleanest cup; see our comparison of paper, metal and cloth filters.

A gooseneck kettle

The thin spout lets you pour slowly and exactly where you want. It is the one upgrade that changes pour over the most; here is why a gooseneck kettle matters.

A scale with a timer

Weighing coffee and water, and timing the pours, is what makes a recipe repeatable. These are the reasons to use a coffee scale.

A burr grinder

Fresh, even grounds extract evenly. Blade grinders make a mix of dust and boulders that brews sour and bitter at once.

How to Make Pour Over Coffee, Step by Step

Pour over for one large cup

20 g coffee, 320 g water at 200 to 205°F (93 to 96°C). About 3 to 4 minutes.

  1. Heat the water. Grind 20 g of coffee medium-fine, like table salt.
  2. Put the filter in the dripper and rinse it with hot water. This removes the papery taste and warms everything. Pour the rinse water away.
  3. Add the coffee, shake it level, set it all on the scale and zero it.
  4. Bloom: start the timer and pour about 50 g of water, just enough to wet all the grounds. Wait until 0:45 while the coffee bubbles and releases gas.
  5. Pour slowly in small circles, staying off the filter walls, until the scale reads 180 g at about 1:15.
  6. Pause until about 1:30, then pour again to 320 g by about 2:00.
  7. Give the dripper a gentle swirl to flatten the bed and let it drain. It should finish between 3:00 and 3:30.

The bloom is the step people skip most, and it matters. Fresh coffee is full of carbon dioxide, and until it escapes the gas pushes water away from the grounds. Our guide to the coffee bloom explains what you are seeing in those first 45 seconds.

Hit the gram targets at roughly these times and the brew will land in the right range. If the drawdown runs much past 3:30 or finishes before 2:45, adjust your grind.

Dialing In: Grind Size and Brew Time

Brew time is your best clue. If the water rushes through and the coffee tastes sour, thin or weak, the grind is too coarse: go a step finer. If it drains slowly, stalls, or tastes bitter and dry, the grind is too fine: go a step coarser. Change only the grind until the time is right, then adjust the ratio for strength. Our grind size guide shows what medium-fine looks like, and why coffee tastes bitter, sour or weak explains the taste side of the same problem.

How Long Should Pour Over Take?

For a single cup, aim for about 3 minutes from the first pour to the last drip, and treat 2½ to 4 minutes as the working range. The dripper changes where you land in that range, because each one drains at a different speed:

DripperGrindTotal brew time
Hario V60Medium-fine2½–3½ minutes
Kalita WaveMedium3–4 minutes
ChemexMedium-coarse3½–5 minutes

Light roasts often taste best toward the longer end of each range. Dark roasts usually taste best toward the shorter end, before bitterness creeps in.

Common Pour Over Mistakes

Using pre-ground coffee

Ground coffee loses aroma within the hour, and pour over shows it more than any other method. Grind right before you brew.

Pouring boiling water

Water straight off a rolling boil scorches the grounds and pulls bitterness. Let it rest 30 seconds.

Skipping the bloom

Trapped gas keeps water from wetting the coffee evenly, so the cup comes out sour and flat.

Not rinsing the filter

Dry paper adds a cardboard taste and leaves the dripper cold.

Pouring on the filter walls

Water that runs down the paper skips the coffee entirely and dilutes the cup. Keep the stream in the middle.

Dumping the water in fast

Flooding the dripper churns the bed and causes uneven extraction. Pour in slow, steady stages.

Brew the recipe above as written a few times before you change anything. Once it tastes good, adjust one thing at a time, grind first, then ratio, and you will have a pour over recipe that is entirely your own.
