How Much Coffee Per Cup & a Coffee To Water Calculator For the Golden Ratio

A huge part of making great coffee is knowing how much coffee per cup that you need.

Measuring the right amount of coffee can make or break a cup of coffee.

So first, we’ve got a quick cheat sheet for you for how much coffee you need per cup. You can use these ratios for how much ground coffee you need and how much coffee beans you need.

Though we really, really recommend using beans instead of grounds.

You can also use our handy calculator tool.

After that, if you’re still hungry for more coffee nerdiness, we’ll talk about the different ratios you can use to measure coffee, and whether you should measure with tablespoons or grams.

Remember:

Following the correct ratio, along with paying attention to grind size, water temperature, and brew time make a good cup of coffee.

Cheatsheet: coffee to water ratios for cups of coffee

Note: This cheat sheet uses the 1:12 ratio, which is roughly 60 grams per liter, or 15 grams for every 225 ml(7.5 oz).

You can use these measurements for any kind of coffee except for cold brew. Use it for coffee grounds or beans, both work.

It’s worth noting that the perfect coffee to water ratio is more of a range: anywhere between 1:12 to 1:15 will yield a decent cup, and the best way to figure out what you like is to experiment.

How much coffee for 1 cup?

Using the 1:12 ratio, use 15 grams or 2 tablespoons of coffee. Using the 1:15 ratio(milder cup), use 12 grams or roughly 1.5 tablespoons of coffee.

How much coffee for 4 cups?

For 4 cups, use 60 grams or 8 tablespoons of coffee. For milder coffee, use 48 grams or 6.5 tablespoons.

How much coffee for 6 cups?

For 6 cups, use 90 grams or 12 tablespoons of coffee. For milder coffee, use 72 grams or 9.5 tablespoons.

How much coffee for 8 cups?

For 8 cups, use 120 grams or 16 tablespoons of coffee. For milder coffee, use 96 grams or 12.8 tablespoons.

How much coffee for 10 cups?

For 10 cups, use 150 grams or 20 tablespoons of coffee. For milder coffee, use 120 grams or 16 tablespoons.

How much coffee for 12 cups?

For 4 cups, use 180 grams or 24 tablespoons of coffee. For milder coffee, use 144 grams or 19 tablespoons.

For even larger coffee brews, you may want to pick up a coffee urn.

Here's a little timer for your french press brew

TIME : 4:00

For brewing most kinds of coffee, you can follow something called the “Golden Ratio”: 2 heaped tablespoons of coffee beans or ground coffee per cup. A standard cup of coffee uses 6 ounces of water.

You can always adjust up or down depending on your taste preferences, but 2 tablespoons will generally produce the best, richest coffee.

This ratio is applicable for all brewing methods: drip coffee pot, pour over, french press coffee, percolator, and espresso brewed coffee.

The question of coffee and water most often comes up with making a brew in a coffee pot, but really, this proportion works for all brewing methods except cold brew.

Tablespoons or grams?

When brewing coffee, using a scale is extremely important. You just can’t get the same level of accuracy with a tablespoon as you can with grams.

You can try doing this yourself. Grab a scale, and measure out what you think is 1 tablespoon of grounds three separate times.

Chances are you’ll get a slightly different weight measurement every time.

Tablespoons of coffee grounds vs tablespoons of coffee beans

Two tablespoons of coffee grounds will not have the same mass as two tablespoons of beans.

Because the beans are larger and irregularly shaped, there’s a lot more air in the tablespoon of beans vs the tablespoon of grounds.

As a result, you’ll probably find that one tablespoon of coffee grounds will weigh more than one tablespoon of coffee beans.

The lesson? Use a scale for the best, most consistent coffee. And use beans instead of grounds. 

For best results, you want to use freshly roasted beans anyway, so why spoil your pick-me-up with pre-ground coffee?

How many grams of coffee in a tablespoon?

One tablespoon of coffee grounds is between 5 to 7 grams. There’s no exact measurement because you may be measuring out fine or coarse grounds.

If you measure out coffee beans, there will be a slight difference between light and dark roasts, as dark roast beans are smaller in volume, so you’ll get more grams of beans per tablespoon.

There are grams to tablespoons conversion charts available online(such as this one) but they are not too accurate because they don’t take density into account. One tablespoon of mercury will weigh a lot more than one tablespoon of water!

If you don’t have a scale on hand, you can use 2 tablespoons for every cup you wish to brew, as noted above.

How many tablespoons in a coffee scoop?

Here’s where things get interesting. Coffee scoops are not standardized as far as I know, so using “scoops” as a measurement is not very accurate.

Many coffee makers come with scoops that are equal to one tablespoon, but the Aeropress, for example, comes with a scoop that is about 2 tablespoons.

So even if your coffee maker shipped with a scoop, it’s better to use a known tablespoon measure rather than any old scoop.

Is there such a thing as a perfect coffee ratio?

Technically speaking, there is. It’s called the Golden Cup Standard, defined by the Specialty Coffee Association as:

Coffee shall exhibit a brew strength, measured in Total Dissolved Solids, of 11.5 to 13.5 grams per liter, corresponding to 1.15 to 1.35 “percent” on the SCA Brewing Control Chart, resulting from a solubles extraction yield of 18 to 22 percent*.

The coffee to water ratio I’ve given above is not set in stone, of course, so you are more than free to play with the amount of coffee to adjust the strength.

Realistically, you’re not going to measure the TDS of cups of coffee, but the ratios given here will get you in a close enough range.

For an everyday coffee drinker, remember, all that matters is how the coffee flavor tastes for you!

The best way to tune your cup of coffee is to keep everything constant and change one variable at a time.

For example, if you make drip coffee but wish to change the flavor a little, keep the brewing method the same, keep the coffee brand and roast the same, keep the grind the same, and just add a few more grams of coffee.

OR

Try using a slightly darker roast for a richer flavor.

If you want a lighter coffee, you can use a few grams less, or use a lighter roast.

The important thing with coffee is measurement! Measure, measure, measure, and you’ll get consistent results every time.

It may also be a wise idea to invest in a coffee scale to help you measure.

Hario V60 Coffee Scale
The Hario V60 coffee scale measures in 0.1 gram increments and includes timers for pour over and french press. It's a bit expensive, but the accuracy you get is worth it.

Once you’ve played around a little and gotten a ratio and recipe that you really like, you may find that you enjoy your coffee straight black instead of with milk and sugar.

You will also find that using the exact same coffee and the exact same measurement with a different brewing method will completely change the taste.

So many variables can be quite overwhelming, so here’s a quick reference for the kind of taste to expect:

  • French press: bold coffee and full mouthfeel
  • Drip or pour over: balanced coffee and clean mouthfeel
  • Espresso: intense, bold coffee and thick mouthfeel
  • Percolator: bold coffee and medium mouthfeel
  • Aeropress: bold coffee and clean mouthfeel

You can then use the coffee to water ratio to adjust. Add more ground coffee for extra boldness, or reduce the amount of ground coffee to dull the boldness down.

How to brew great coffee every time

Coffee is such a universal and versatile drink that there are really plenty of ways to brew coffee, but a few elements will always remain the same.

Aside from using the correct amount of coffee, you can consider these the laws of coffee brewing:

  • Use freshly roasted beans. I can’t repeat this enough times. Once you’ve tasted coffee made from freshly roasted beans, you’ll never be able to drink pre-packaged supermarket coffee again.
  • Grind freshly roasted beans just before brewing. Grinding just before brewing ensures that most of the flavors remain trapped in the coffee bean, only exposing them just before you brew. Once you grind coffee beans, they lose most of their flavor in a very short time. Use an automatic or manual burr grinder to get your ground coffee.
  • Use the correct water temperature. If your water is too hot, you risk burning your coffee. If it’s too cold, you won’t get enough flavor extraction. You need to brew at the perfect temperature – which is around 90 to 95 degrees C. For real temperature sticklers, there are SCAA-certified coffee makers that brew at 200 degrees.

Use the grind chart below as a reference to get your grinds right:

How much coffee for cold brew?

For cold brew, the ratio changes quite significantly. Because you’re now brewing with cold water instead of hot water, the molecules are moving much more slowly and they need a lot more coffee to interact with in order to extract the flavor.

There are a wide variety of tastes and preferences when it comes to cold brew, but you can use ratios of anywhere between 1 parts coffee to 8 parts water up to 1 part coffee to 2 parts water.

The more coffee you use, the more concentrated and strong the drink will be – so you may want to use it as a concentrate that you dilute with water or milk instead of something you drink straight.

Here’s a cheat sheet for cold brew:

  • Strong concentrate: 500 grams of coffee for every liter of water
  • Medium concentrate: 250 grams of coffee for every liter of water
  • Dilution you can drink right away: 125 grams of coffee for every liter of water

How much coffee for pour over?

There’s a pretty wide spectrum you can use for pour over. Personally, I love the 1:15 ratio for pour over, but you can certainly use 1:12 or 1:17.

The best way to see what suits you best is to experiment with a couple of brews.

Making so much coffee may seem a little wasteful, but a little hack you can employ is to just brew less coffee using the same ratio.

How much coffee for french press?

French press is very forgiving, so you can use 1:12 for a very strong brew and even go down to 1:15 or 1:17 for a lighter brew.

In the video above, the 1:12 ratio yields a very strong wake-up call brew, and 1:15 yields a pleasant brew that you will enjoy sipping.

How much coffee for Aeropress?

Aeropress is a really interesting brew method. The original recipe calls for using one heaped scoop for one cup of coffee. The scoop is around 2 tablespoons.

That works out to about 14 or 15 grams as we saw above.

Some Aeropress recipes even call for using 30 grams of coffee per cup, which yields an incredibly bold cup.

Personally, I prefer sticking to 14-15 grams, adding water up to the 1 mark, and diluting the resulting shot with another 150 ml of water for a really sweet and satisfying cup.

Conclusion

As you can see, the question of how much coffee per cup is much more nuanced than you’d think! There are good benchmarks to start from such as the golden ratio, but after that, it’s up to you to experiment and fine tune your brewing methods to the way you like it.
