How Much Coffee for an 8-Cup French Press

The short answer: 67 grams of coffee with 1 liter (1000 g) of water for a full 8-cup French Press at the standard 1:15 ratio. That's about 8 level tablespoons of medium-roast whole-bean coffee, brewed in roughly 5 minutes. Here's the full procedure, the math behind the numbers, and how to adjust for stronger or lighter cups.

The exact answer for an 8-cup press

Variable	Value
Coffee	67 g, coarse grind
Water	1000 g (1 liter) at 200 °F (93 °C)
Ratio	1:15
Steep time	4 minutes
Yield	33 oz brewed coffee (about 4 mugs)

67 g is roughly 8 level tablespoons of medium-roast whole-bean coffee. If you don't have a scale, this gets you close — but coffee density varies by roast and origin, so a scale is the only way to be repeatable. See French Press Measurements for the full conversion chart.

Why 67 grams, not a round number

An 8-cup French Press is a marketing label — each "cup" is 4 oz of finished brew, so the total is 32 oz, but with the bed of grounds at the bottom you get back about 1 liter (33–34 oz) of usable coffee. At the standard 1:15 brew ratio, 1000 g of water needs 1000 / 15 = 66.67 g of coffee. Round to 67 g for ease of weighing.

Don't sweat 1–2 g either way. The 1:15 ratio is forgiving over a ±5% range. Where it matters: don't be off by 10+ grams (which is roughly 1.5 tablespoons), or the cup will taste noticeably weak or harsh.

Step-by-step: brewing the 8-cup press

Heat 1 liter of water and pre-warm the press. Bring water to a boil, then let it sit 30 seconds. Pour about a cup into the empty French Press, swirl, discard. Cold glass robs heat from the bloom and shifts your extraction.
Weigh 67 g of coffee and grind coarse. Aim for a kosher-salt or breadcrumb texture. On a Baratza Encore, that's 28–32. Add to the warm, empty press.
Bloom (0:00 – 0:30). Start the timer. Pour about 134 g of water — twice the coffee weight — over the grounds. Stir gently for 10 seconds. Wait until 0:30. CO₂ bubbles release.
Add the rest of the water (0:30 – 1:00). Pour to 1000 g total. Stir gently. Place the lid with the plunger pulled all the way up.
Steep (1:00 – 4:00). Don't disturb the brew. Three full minutes of immersion.
Press slowly (4:00 – 4:30). Push the plunger down with steady, even pressure over about 30 seconds. Stop just above the grounds at the bottom.
Serve immediately, decant the rest. Pour what you'll drink in the next few minutes; decant the leftover to a thermal carafe so it stops extracting on the grounds.

Adjusting strength: ratio variants for an 8-cup press

Style	Coffee (g)	Water (g)	Ratio	Cup character
Light	59	1000	1:17	Brighter, more delicate, less body
Standard	67	1000	1:15	Balanced — the recipe to start with
Stronger	77	1000	1:13	Denser, more concentrated, fuller body
Very strong	91	1000	1:11	Intense — best with bold dark roasts

Move in 5-g steps to dial in. Tightening the ratio is the cleanest way to add strength; extending the steep time past 5 minutes is the worst way (it pulls in bitterness without adding pleasant body).

Recommended Doctopus coffees for the 8-cup pour

When you're brewing for two or more, you want a coffee that holds up to dilution, milk additions, and the longer time it sits in a thermal carafe.

Cerrado Catuai — Brazil natural. Cocoa, nut, mellow acidity. The most forgiving choice for an 8-cup brew: it tastes the same in cup 4 as it did in cup 1, which matters when you're sharing.
Dembi Sidama — Ethiopia natural. Berry, sweet, complex. More distinctive than Cerrado; reward for the curious drinker.
Argelia Cauca — Colombia washed, women producers. Toffee, balanced. Lighter than the typical French Press pick but reads cleanly through the metal mesh.

If your press is a different size

The 1:15 ratio scales linearly with water weight. Use this:

3-cup (12 oz): 350 g water, 23 g coffee
4-cup (17 oz): 500 g water, 33 g coffee
6-cup (25 oz): 750 g water, 50 g coffee
8-cup (34 oz): 1000 g water, 67 g coffee ← this page
12-cup (51 oz): 1500 g water, 100 g coffee

Note: water weights are slightly less than the manufacturer label's total volume — that's because of the immersion overhead (water level rises when you add coffee, and you don't fill to the very top).

Grind size for an 8-cup pour

Coarse. A bigger press doesn't change the grind requirement — it scales the same recipe up. Use a kosher-salt or breadcrumb texture. Common settings:

Baratza Encore: 28–32
Comandante C40: 28–32 clicks
1Zpresso JX: 90–110 clicks
Fellow Ode (Gen 2): 9–11

If pressing the larger volume feels harder than your usual smaller brew, grind one click coarser. Resistance scales with surface area, so larger presses with the same grind take slightly more effort.

8-cup French Press FAQ

How much coffee for an 8-cup French Press?

67 g of coffee with 1000 g of water (1 liter) at the standard 1:15 ratio. That's about 8 level tablespoons of medium-roast whole-bean coffee.

How many tablespoons of coffee for an 8-cup French Press?

About 8 level tablespoons of medium-roast whole-bean coffee. Tablespoon weights vary by roast level (5–6 g per tablespoon for medium roasts), so use a scale for repeatable results.

How long does an 8-cup French Press take to brew?

About 5 minutes total: 30-second bloom, 3-minute steep with the lid on, 30 seconds for a slow press, and the rest is heating water and grinding coffee.

How much water for an 8-cup French Press?

1 liter (1000 g, about 34 oz). The "8-cup" label uses 4-oz measuring cups, so the total volume is roughly 32 oz; in practice you brew with 1 liter and yield about 33 oz of finished coffee.

Can I make less than a full 8-cup brew in an 8-cup press?

Yes, down to about 500 g of water (4 cups). Below that, the brew gets cold quickly because the grounds and water lose too much heat to the empty glass above. For a one-mug brew, a 4-cup press is a better tool.

What happens if I add more coffee than 67 g to an 8-cup press?

The cup gets stronger and denser. At 77 g (1:13) it's noticeably more intense; at 91 g (1:11) it's pushing toward concentrate territory. Don't go past 100 g for a normal 8-cup brew — the bed gets so dense the press becomes hard to push down.
