Best Pour Over Ratio (2026): Start at 1:16

What is the best pour over ratio?

The best pour over ratio is 1:16 by weight: 20 g coffee to 320 g water. That ratio makes a balanced cup for most drippers, then gives you room to move. Use 1:15 when the cup tastes thin and 1:17 when it feels too heavy. Light roasts usually want a touch more water — our light-roast pour-over ratios adjust for it.

Think of ratio as the strength dial. More coffee for the same water tastes fuller, like turning up the volume. Less coffee tastes lighter. Extraction — how much flavor the water pulls from the grounds — is a different knob, and it mostly comes from grind size, pouring, temperature, and contact time.

Stone Creek Coffee presents 1:16 as a common starting point, while Stumptown Coffee Roasters recommends a general 1:17 and says to adjust by taste. That is the useful range: start simple, then listen to the cup.

What do you need to brew by ratio?

You need fresh coffee, filtered water, a paper filter, a pour-over dripper, a kettle, a grinder, and a scale that reads to 0.1 g. The scale matters most because grams stay honest. Scoops change with bean size, roast level, and how casually you fill them.

• Coffee: 20 g, freshly ground if possible.
• Water: 320 g filtered water for the main recipe.
• Filter and dripper: rinse the paper first so your cup does not taste papery.
• Kettle: a gooseneck helps with control, but any kettle can work if you pour gently.
• Scale: weighing coffee and water is more repeatable than scoop measurements; see our coffee scale picks for pour over if your current scale jumps around.
• Grinder: aim for a medium-fine grind, around table salt with a few sandy bits.

A ratio transfers from brewer to brewer, but flow changes with dripper shape, hole size, and filter thickness. If you are still picking your setup, our guide to choosing a pour-over coffee maker explains why some brewers drain more slowly than others.

How do you brew pour over at a 1:16 ratio?

Brew 1:16 by rinsing the filter, weighing 20 g of coffee, blooming the grounds, then pouring to 320 g total water. Keep your grind, water heat, and pouring style steady for this first cup. That way, your next change tells you something useful.

Step 1: Rinse the filter and heat the brewer

Put the filter in the dripper and rinse it with hot water. Dump that rinse water before brewing. Counter Culture Coffee includes rinsing, setup, and controlled pouring in its pour-over guide, and the rinse is the easy part to get right.

Step 2: Weigh 20 g coffee and grind it

Weigh 20 g of beans, then grind medium-fine. If the grounds look like powder, the brew may stall and taste bitter. If they look like chunky sea salt, water may rush through and leave the cup sharp and hollow.

Step 3: Bloom with 40–60 g water

Start the timer and pour 40–60 g of water over the dry grounds, making sure everything gets wet. Wait 30–45 seconds. The bloom lets trapped gas escape, so the later pours can soak the bed more evenly.

Step 4: Pour to 320 g total water

Pour in slow circles until the scale reads 320 g total water. You can do this in two or three pours; just avoid blasting the same spot. Counter Culture’s guide also stresses controlled water flow, which matters because uneven pouring can leave one area more extracted than another.

Step 5: Let it drain, taste, and change one thing

Let the coffee finish dripping, then taste it while it cools a little. If the strength feels close, keep the 1:16 ratio and adjust grind next time. If the flavor is nice but the cup feels too thin, try 1:15. If it feels heavy or too intense, try 1:17.

What mistakes make pour over ratios confusing?

The biggest mistake is treating ratio like a magic flavor knob. Ratio mostly changes strength: how concentrated the cup feels. Extraction — how much flavor water pulls from the grounds — comes more from grind size, pour speed, water temperature, and contact time. Keep those separate and troubleshooting gets easier.

• Changing three things at once — if you change ratio, grind, and pouring style together, you will not know what fixed the cup.
• Using scoops for water and coffee — scoops are fine for camping, but they are imprecise for repeatable brewing.
• Ignoring flow — a brewer that drains in two minutes will taste different from one that drains in four, even at the same ratio.
• Chasing a perfect number — Stone Creek, Stumptown, and Counter Culture all point toward measured brewing, but they still leave room for taste.

How do you fix weak, bitter, or sour pour over?

Fix the cup by changing one thing at a time, starting with grind before ratio. Weak but clean coffee may need 1:15. Bitter, drying coffee usually needs a coarser grind or shorter contact time. Sour, sharp coffee usually needs a finer grind or a slower pour.

Weak but pleasant

Move from 1:16 to 1:15: 20 g coffee to 300 g water. That makes the cup stronger without changing the grind setting.

Bitter, harsh, or drying

Keep the 1:16 ratio and grind a little coarser first. Bitter coffee often means the water pulled too much from the grounds, so adding more water may make a larger bitter cup instead of a better one.

Sour, sharp, or hollow

Keep the dose and water the same, then grind a touch finer or pour a bit slower. A consistent grind helps you isolate ratio changes later, so a burr grinder suited to pour over is worth it if your cups swing wildly from day to day.

Too intense but not bitter

Move from 1:16 to 1:17: 20 g coffee to 340 g water. This makes the cup lighter without changing its basic flavor direction.
