What is the best coffee to water ratio?

It depends on how you brew. For pour over, start at 1:16: 1 gram of coffee for every 16 grams of water, the specialty standard. For a drip machine, start at 1:24, the middle of what coffee maker charts recommend, and go to 1:18 for the Specialty Coffee Association's Golden Cup strength. Then adjust by taste, one step at a time.

How much coffee per cup of water?

For an 8 oz cup, about 10 grams, or 2 level tablespoons, at 1:24. The National Coffee Association's rule of thumb is 1 to 2 tablespoons per 6 ounces. Check which cup you mean: on the drip machines we cover, a "cup" on the carafe is 4 to 6.8 oz, not 8.

What is the coffee to water ratio for a French press?

1:15, with a coarse grind: about 67 grams of coffee for a 34 oz (1 liter) press. Try 1:12 if you like it heavy. Steep four minutes, press, and pour it all off so it stops brewing.

What is the coffee to water ratio for cold brew?

1:8 to drink straight, coarse ground and steeped 12 to 18 hours in the fridge. At 1:5 you get a concentrate to cut with water or milk, about half and half. See our cold brew coffee makers guide for the jars and makers.

What is the coffee to water ratio for a drip coffee maker?

1:24: about 42 grams of coffee per liter of water in the tank. Measure the water you pour in, not the cup marks on the carafe, which differ from machine to machine.

Why does my coffee maker's chart say fewer tablespoons?

Because machine charts brew lighter than the specialty standard. Ninja's chart for the CM401, for example, says 8 to 12 level tablespoons for a full carafe, about 1:22 to 1:33, while the Specialty Coffee Association's Golden Cup is about 1:18. Ninja's own tested dose, 77 grams for a full carafe, sits at that stronger end. Neither is wrong: the calculator's Light matches the chart's low end and Bold the specialty standard.

How many tablespoons of coffee for 12 cups?

It depends on the cup. Twelve 8 oz cups is 96 oz, about 118 grams or 23.5 tablespoons at 1:24. Twelve cups on a coffee maker's carafe is usually 60 oz (a 5 oz cup on most), about 74 grams or 15 tablespoons.

What ratio is espresso?

Espresso is measured the other way round, coffee in to drink out: 18 grams in, 36 grams out (1:2) in 25–30 seconds is the usual start. Our espresso grind size guide covers dialing it in.
