How to Dial In Pour-Over Coffee

To make a good pour-over, weigh 22 grams of coffee to 350 grams of water, a 1:16 ratio, grind to the texture of coarse sand, and use water at about 200F. Wet the grounds for a 30 to 45 second bloom, then pour in slow spirals until the whole cup finishes in roughly two and a half to three minutes. Dialing in is the small loop after that: taste, change one variable, brew again.

Start with the ratio, because it sets everything else. The Specialty Coffee Association anchors brewed coffee around 55 grams of coffee per liter of water, give or take ten percent, which lands close to 1:18, and 1:16 is the friendliest place to begin: one gram of coffee for every sixteen grams of water. For a single mug that is 22 grams of coffee to 350 grams of water. If the cup tastes thin and washed out, move toward 1:15. If it tastes heavy or muddy, move toward 1:17. The reason to weigh rather than scoop is that a tablespoon of dense, oily beans and a tablespoon of light, airy ones differ by several grams, and that swing is enough to move a cup from balanced to sour. Our coffee-to-water ratio guide walks through the math for every brew size.

Grind is the next lever, and it is the one most home brewers get wrong. For pour-over you want medium, close to coarse sand or table salt. Too fine and the bed clogs, water pools, and the cup turns bitter and harsh. Too coarse and the water rushes through before it pulls enough out, and the cup turns sour and thin. The single biggest upgrade most people can make is moving off a blade grinder, which chops beans into a mix of dust and boulders, onto a burr grinder that produces an even particle size. Our grind size chart by method shows exactly where pour-over sits relative to French press and espresso.

Water temperature comes next. The SCA recommends a brew temperature of 195F to 205F, so 200F is the target most recipes aim for. You do not need a thermometer: water just off a rolling boil drops into that window after it rests 30 to 45 seconds, which is conveniently about the time it takes to rinse your filter. Cooler water under-extracts and leaves the cup sour and flat; water at a hard boil can scald the grounds and pull out bitterness. If you want the deeper version, including how mineral content changes the taste, our water for coffee guide covers temperature and water chemistry together.

The bloom is the step that separates a clean cup from a flat one. When hot water first hits fresh grounds, trapped carbon dioxide escapes in a rush of bubbles that pushes water away and blocks even saturation. So you pour about twice the coffee weight in water, roughly 45 grams for a 22 gram dose, wet every ground, and wait 30 to 45 seconds for the gas to vent. Fresh, recently roasted coffee blooms dramatically, doming up and fizzing; stale coffee barely moves, which is a useful freshness test. After the bloom settles, pour the rest of the water in two or three slow, controlled pulses, moving in spirals from the center outward and keeping the stream off the paper. A gooseneck kettle makes that pour controllable, which is why we cover it in the gooseneck kettle guide.

Now the actual dialing in. Brew once by the numbers above, then taste and read the cup. Sour, sharp, or weak means under-extraction: the water did not pull enough out. Fix it by grinding finer, brewing hotter, or slowing the pour so contact time goes up. Bitter, dry, or hollow means over-extraction: too much came out. Fix it by grinding coarser, lowering the temperature slightly, or pouring faster. The discipline is to change one variable at a time, grind first since it has the biggest effect, and rebrew. If you want the full diagnostic, the V60 head-to-head in our V60 vs Chemex vs French press breakdown shows how the same beans taste different through each brewer.

Two checks tell you whether the brew went well without tasting. First, time it: a single 350 gram cup should finish draining in about two and a half to three minutes from the first pour. Much faster points to a grind that is too coarse; much slower points to one that is too fine or a pour that flooded the filter. Second, look at the spent bed. A flat, level bed means the water moved through evenly; grounds climbing the filter walls or a deep crater in the center means the pour was uneven. Both are easier to control with a scale that has a built-in timer, so you can watch weight and time at once.

The last variable is the coffee itself, and it is the one no technique can fix. Dialing in works only with beans that were roasted recently and ground moments before brewing. A light, washed single-origin from a specialty coffee shop is built for pour-over, where the method's clarity shows off the bean's acidity and fruit. In Bushwick, Sey Coffee roasts in a deliberately light, Nordic-influenced style designed to keep each coffee transparent, exactly the kind of bean that rewards a careful pour. Once your recipe is locked, the rest of the kit, the dripper, the filters, the carafe, is covered in our pour-over set for beginners, and you can read the technique in context in the brewing fundamentals handbook or browse the full kit on the gear page. For your V60 or any cone dripper, the recipe above is the same starting point.
