How Much Coffee for an 8 Cup French Press? Amounts for 3, 4, 8 and 12 Cups
Share
The most popular French press size is the “8 cup” model, and it causes the most confusion. So, how much coffee for an 8 cup French press? Use about 56 to 75 grams of coarse-ground coffee (roughly 11 to 15 level tablespoons) for 900 ml (about 30 fl oz) of water. Start at 64 g, about 13 tablespoons, for a balanced pot. The reason it is less water than you might expect: an 8 cup press holds 1 liter (34 oz), its “cups” are only 4 oz each, and the grounds and the plunger need room.
Below you will find the same math for 3, 4 and 12 cup presses, a ready-to-print chart, and how to adjust for your taste.
Key takeaways
- French press makers such as Bodum count a cup as 4 oz, so an 8 cup press holds 1 l (34 oz), enough for about two and a half 12 oz mugs.
- The National Coffee Association suggests 1:10 to 1:16 coffee to water by weight for French press; 1:14 is a good middle.
- Fill to about 90 percent of the press’s capacity to leave room for grounds and bloom.
- 8 cup press: 64 g of coffee (about 13 tbsp) to 900 ml of water at 1:14.

What “cup” means on a French press
Bodum, the brand behind the classic Chambord, bases its serving sizes on a 4 oz coffee cup. That is half a standard 8 oz measuring cup and about a third of a typical mug. Here is what the common sizes really hold:
| Press size | Capacity | Practical water (about 90%) | 12 oz mugs it fills |
|---|---|---|---|
| 3 cup | 0.35 l (12 oz) | 320 ml (11 oz) | About 1 |
| 4 cup | 0.5 l (17 oz) | 450 ml (15 oz) | About 1 |
| 8 cup | 1 l (34 oz) | 900 ml (30 oz) | About 2.5 |
| 12 cup | 1.5 l (51 oz) | 1,350 ml (46 oz) | About 3.5 to 4 |
Why only 90 percent? Coarse grounds take up space, fresh coffee foams as it releases gas, and you need headroom for the plunger. Filling right to the spout often leads to overflow and grounds in your cup.
French press coffee amounts chart
Numbers below use practical water amounts and assume a level tablespoon of coarse-ground coffee weighs about 5 g. Coarse grounds vary, so grams are more reliable than spoons.
| Press | Water | Mild (1:16) | Balanced (1:14) | Strong (1:12) |
|---|---|---|---|---|
| 3 cup | 320 ml | 20 g (4 tbsp) | 23 g (4.5 tbsp) | 27 g (5.5 tbsp) |
| 4 cup | 450 ml | 28 g (5.5 tbsp) | 32 g (6.5 tbsp) | 38 g (7.5 tbsp) |
| 8 cup | 900 ml | 56 g (11 tbsp) | 64 g (13 tbsp) | 75 g (15 tbsp) |
| 12 cup | 1,350 ml | 84 g (17 tbsp) | 96 g (19.5 tbsp) | 112 g (22.5 tbsp) |
To scale any other size: divide the water in milliliters by your ratio number. For example, 600 ml at 1:15 needs 600 ÷ 15 = 40 g of coffee.
How much coffee for an 8 cup French press: a worked example
Here is the full process for a 1 l press at the balanced 1:14 ratio:
- Weigh 64 g of coffee (about 13 level tablespoons), ground coarse, like rough sea salt.
- Heat 900 ml of water to just off the boil. The NCA suggests about 93 °C, plus or minus 3 °C; letting boiled water rest around 30 seconds gets you close.
- Pour about a third of the water, enough to wet all the grounds, and wait 30 to 60 seconds while the coffee blooms.
- Add the rest of the water up to the 900 ml mark, about 2 to 3 cm below the spout.
- Steep 4 minutes in total. At the one-minute mark, gently stir or break the crust.
- Press slowly over 15 to 20 seconds, then pour everything out right away so it does not keep extracting.
Making less than a full pot? Keep the same ratio. For two mugs in an 8 cup press, use 600 ml of water and about 43 g of coffee.
Without a scale
Use a standard tablespoon, level each spoon with a knife, and count 13 for a full 8 cup press. If your “scoop” is a coffee scoop, check its size first: many are 2 tablespoons, which would make it about 6.5 scoops.
Adjusting strength (and what not to change)
| Your cup tastes… | Try this first | Avoid |
|---|---|---|
| Weak but clean | Move from 1:16 to 1:14 or 1:12 | Steeping 10 minutes; it adds bitterness, not strength |
| Strong and bitter | Grind a little coarser, or use 1:15 | Cutting the steep to 2 minutes |
| Thin and sour | Hotter water and a full 4 minutes | Grinding fine; it clogs the mesh |
| Silty | Coarser, more even grind; pour gently | Pressing hard and fast |

The best coffee for a French press
A press keeps the coffee’s oils in the cup, so full-bodied, chocolatey coffees shine. Our Cowboy Blend combines dark and medium roasts with cocoa, caramel and vanilla tones. Brazil Santos is a balanced medium roast with cocoa and nuts and low acidity, very forgiving in a press. Choose the Coarse grind at checkout if you do not own a grinder; it is cut specifically for French press and cold brew. Every bag is roasted 1 to 5 days before delivery.
