Coffee Ratio for Drip Coffee (2026): Easy Chart

How much coffee should you use for drip coffee?

Divide your water weight by 17 to get your coffee dose in grams. Counter Culture Coffee's “Coffee Basics: Brewing Ratios” recommends this 1:17 starting point. For kitchen calculations, 1 mL of water weighs about 1 g. Measure the water going into the reservoir, not the brewed coffee coming out.

What do you need to measure your batch?

You need a drip brewer, its matching filter, coffee, water, and a gram scale or marked measuring jug. A scale removes the guesswork from whether a scoop is level or heaped. If you already own a kitchen scale that reads grams, start there before buying another tool.

• Coffee: medium-ground, as recommended in Starbucks Coffee at Home's drip-brewer guide.
• Water container: a jug you can zero on the scale before filling.
• Brewer manual: check cup definitions, minimum batch size, and basket limits.

How do you calculate and brew any batch size?

Measure your water first, calculate the dose, then load the machine and brew. Keep the same beans and grind for the first adjustment so you can tell what changed. Write down water grams and coffee grams rather than “six cups and a few scoops.” That recipe travels between brewers.

1. Measure the actual water

Put an empty jug on the scale and press tare, which resets the display to zero. Add your batch water. If you're checking a reservoir line, fill the carafe to that line with cold water and weigh it separately. Never put the whole powered brewer on the scale.

2. Divide by 17 and weigh the grounds

For 900 g of water, calculate 900 ÷ 17 = 52.9 g, then weigh 53 g of coffee. Stay within the scale's capacity, including the container. If necessary, weigh water in smaller portions and add their weights.

No scale? Starbucks Coffee at Home's “How To Brew - Drip Brewer” uses 2 tablespoons per 6 US fluid ounces of water. That's about 177 mL. A scoop labeled “2 tablespoons” replaces those two spoonfuls; an unlabeled scoop needs checking. There is no dependable universal grams-per-scoop conversion.

3. Load, brew, and save the recipe

Add the filter and weighed grounds, then pour your measured water into the reservoir. Run the usual brew cycle. Record the dose and grind setting alongside a quick taste note: watery, pleasantly full, or harsh.

With a built-in grinder, check whether its dose control measures time or weight. Weigh the grounds if the manual allows safe access. Want that combined workflow? See Best Grind and Brew Coffee Maker Under $200 (2026) Compared for brewer-and-grinder options.

Which measurement mistakes should you avoid?

Avoid treating machine cups as mug sizes, using finished coffee volume for the calculation, or packing extra grounds into a full basket. The ratio describes the coffee and water you start with. Your manual's limits still apply, even when the math suggests a bigger dose than the basket can hold.

• Mixing units: fluid ounces measure volume; ounces on a scale measure weight. Use grams and milliliters here.
• Ignoring container weight: tare removes it from the display, but it still counts toward maximum scale capacity.
• Changing everything: don't swap beans, dose, and grind together. You'll lose track of the useful change.

What should you change if coffee tastes weak or bitter?

For weak but otherwise pleasant coffee, try more grounds. For harsh coffee, check grind before simply cutting the dose. Counter Culture's brewing-ratio guide separates strength from extraction: a full-bodied cup can still taste unpleasant. Use these as next-batch experiments, not guarantees, and make one change at a time.

Weak, like coffee-flavored water

Try 1:16: for 500 mL, move from 29 g to 31 g. If it also tastes sharply sour, return to Starbucks' medium-grind starting point before adding still more coffee.

Bitter or mouth-drying

Keep the dose steady and try a slightly coarser grind, especially if you're using powdery espresso grounds. If the flavor is pleasant but simply too intense, test 1:18 instead: about 28 g for 500 mL.
