Pour Over Coffee Ratio
Calculator

The most widely used pour over ratio is 1:15, meaning 1 gram of coffee per 15 grams of water. This produces a balanced, full-flavored cup that works across all dripper types. For a lighter, more delicate cup use 1:17. For something bolder use 1:13. Most specialty coffee shops and professional brewers work between 1:14 and 1:16.

The Hario V60 works best at a 1:15 to 1:16 ratio with a medium-fine grind. For a single 8 oz cup (240 ml), use 15-16 grams of coffee. Total brew time should be 2:30 to 3:30. The V60 rewards technique more than any other dripper, so consistent pour spirals and a gooseneck kettle make a bigger difference here than with more forgiving drippers like the Kalita Wave.

Chemex works best at a 1:15 ratio with a medium-coarse grind. The thick bonded Chemex filter slows flow considerably, so a coarser grind keeps brew time in the right 4:00 to 5:00 window. At 480 ml (2 cups), use 32 grams of coffee. Do not use generic cone filters in a Chemex; the paper is thinner and changes the flow rate significantly, requiring you to adjust your grind.

For one 8 oz cup (240 ml) at a 1:15 ratio, use 16 grams of coffee. Your bloom pour should be about 32 ml (2x the coffee weight). After the 30-45 second bloom rest, add the remaining 208 ml in one or two pours. Total brew time target is 2:30 to 3:30 for most single-cup drippers.

For 2 cups (480 ml) at a 1:15 ratio, use 32 grams of coffee. Bloom with 64 ml (2x coffee weight), wait 35 seconds, then add the remaining 416 ml in two pours of about 200 ml each, waiting for the bed to nearly drain between pours. Check that your dripper has enough capacity for 480 ml. A V60 01 is too small; you need a V60 02 or larger.

Blooming releases trapped CO2 from freshly roasted coffee. When hot water first contacts grounds, CO2 escapes rapidly and the grounds visibly swell and bubble. If you skip the bloom, that CO2 acts as an uneven barrier between water and coffee during your main pours, leading to inconsistent extraction. The bloom takes 30-45 seconds and measurably improves cup quality, especially with fresh beans roasted in the past 2-3 weeks.

Yes, for consistent results a gooseneck is important. The narrow spout gives you flow control, which determines how evenly water saturates the coffee bed. A standard kettle pours too fast and too wide for controlled spiral pours. The one exception is the Clever Dripper, which is a full immersion method where you pour all the water in at once and technique matters much less. For V60, Chemex, Kalita Wave, and Origami, a gooseneck is the upgrade that makes the biggest immediate difference.

Yes, always. Pour about 100-150 ml of hot water through the dry paper filter and dripper into your cup or carafe, then discard it. This removes paper taste and pre-heats the brewing vessel. It takes 30 seconds and makes a noticeable difference, especially with natural (brown) unbleached filters, which carry more paper flavor than bleached white filters.

Target times: V60 is 2:30 to 3:30. Chemex is 4:00 to 5:00. Kalita Wave is 3:00 to 4:00. Clever Dripper is 3:30 to 4:30 including steep time. These timings assume a medium grind, 200 F water, and standard pour technique. If your brew takes significantly longer, your grind is too fine. If it finishes faster, your grind is too coarse. Brew time is the primary diagnostic tool for grind adjustment.

Bitter pour over is almost always over-extraction. Check in this order: grind too fine (most common), water too hot, brew time over 4:30, or too much agitation during pouring. Start by coarsening the grind one click and retiming your brew. If it now finishes in range and still tastes bitter, drop the water temperature by 5 degrees.

You can, but consistency suffers significantly. Use 1.5 level tablespoons of medium-fine ground coffee per 6 oz of water as your starting guideline. A basic kitchen scale under $15 changes pour over from a rough approximation into a real recipe. Pour over is a precision method, and a 2-gram variance in coffee noticeably changes the flavor. If you find yourself struggling to repeat a good cup, a scale is the answer almost every time.

Pour over typically uses a 1:15 to 1:16 ratio while auto drip machines use 1:16 to 1:18. Manual pour over extracts more completely because of the bloom step, controlled pour rate, and consistent temperature throughout. This means you need slightly less coffee per ml of water than most drip machines to reach the same strength. High-end drip machines like the Technivorm and Breville Precision can match pour over extraction at similar ratios.

V60 and Origami: medium-fine (table salt texture). Chemex: medium-coarse (rough sea salt, slightly coarser than V60 due to the thicker filter). Kalita Wave: medium (between V60 and Chemex). Clever Dripper: medium (most forgiving of all). The right grind puts your brew time in the correct window for your dripper. If time is off, adjust grind before touching anything else.

More than most people expect. Pour over produces a cleaner, clearer cup than French press because the paper filter removes oils that would otherwise mask off-flavors. This means water character comes through more clearly in pour over than in any other brew method. Filtered water (75-150 ppm TDS, no chlorine, neutral pH) produces a noticeably cleaner and sweeter cup. If your pour over tastes off even with correct grind, ratio, and temperature, try filtered water before making any other change.
