How Much Coffee Per Cup? Scoops, Grams, and the Right Ratio

Use 1 to 2 tablespoons of ground coffee per 6 oz of water, which is about 10 to 12 grams, or a 1:16 ratio of coffee to water by weight. That ratio is the Specialty Coffee Association's golden cup standard and it works for drip, pour over and most home brewers. The confusion comes from the word "cup", because a coffee maker's cup is 5 to 6 oz rather than the 8 oz cup in your cupboard. So a 12-cup machine makes about 60 to 72 oz, not 96, and needs roughly 10 to 12 tablespoons rather than 12. The other source of error is the scoop: a level coffee scoop is 2 tablespoons, so one scoop per 6 oz cup is right and one scoop per mug is weak. If you want one number to remember, weigh it: 60 grams of coffee per litre of water is the whole standard in a single figure.

Here is the measurement for every size, and why weighing beats scooping. Our Organic Colombia comes ground to order if you would rather skip the grinder step.

How much coffee for how much water?

A level coffee scoop is 2 tablespoons, roughly 10 to 11 g of medium-ground coffee. That number drifts with grind size, which is exactly the problem with measuring by volume.

Why does weighing work better than scooping?

Because a tablespoon of coffee is not a fixed amount of coffee.

Grind size changes how densely the grounds pack. A tablespoon of fine espresso grind holds noticeably more coffee than a tablespoon of coarse French press grind. Roast level changes it too: dark-roasted beans have lost more moisture and expanded more, so they weigh less per unit volume than light-roasted ones.

The result is that the same two scoops can vary by 20% or more in actual coffee, which is enough to take a cup from balanced to sour or bitter. A $12 kitchen scale removes the variable permanently and is the single cheapest upgrade to your coffee.

What ratio should you use for each brewer?

Start at 1:16 and move from there based on the method.

Drip and pour over sit at 1:15 to 1:17. French press runs slightly stronger at 1:12 to 1:15 because the grounds are filtered out by a mesh rather than paper. AeroPress is flexible but often brewed strong at 1:10 to 1:14. Cold brew concentrate is far stronger at 1:4 to 1:8, then diluted in the glass.

Espresso is a different scale entirely, around 1:2, which is why 18 g of coffee yields about 36 g of liquid. Our cold brew guide has the full method for the long end of that range.

Should you adjust for strong or weak coffee?

Adjust the ratio for strength, and the grind for taste. They are different problems.

If the coffee tastes fine but too weak, use more coffee. If it tastes sour, thin and unpleasant, that is under-extraction and the fix is a finer grind, not more coffee. If it tastes bitter and harsh, that is over-extraction and the fix is a coarser grind.

Adding more coffee to fix a sour cup is the most common mistake in home brewing. It makes a stronger sour cup. We covered the bitter end of this in how to make coffee less bitter.

Does the ratio change the CBD per cup?

Yes, directly, and this is worth getting right.

The cannabinoid dose is per gram of coffee, not per cup of water. A 12 oz bag of our coffee carries 300 mg of CBD across roughly 340 g of coffee, so a 21 g mug dose carries somewhere near 18 mg before brewing losses. Brew half as much coffee into the same water and you halve the dose along with the strength.

That is the practical reason to measure rather than estimate: consistency in the ratio is consistency in the dose. More on what reaches the cup in CBD bioavailability, and the per-bag numbers in the range comparison.
