A 34 oz French press is one of the most popular sizes for brewing coffee at home, but figuring out how much coffee to put in it can be confusing. The simple answer is that for a full 34 oz French press, about 60 grams of coffee is an excellent starting point.
That assumes you’re using approximately 1 liter, or 1,000 grams, of water and aiming for a coffee-to-water ratio close to 1:16. If you prefer stronger French press coffee, you can increase the amount to around 65–67 grams.
⚡ Quick Answer: Coffee for a 34 oz French Press
For a full 34 oz French press, try:
Balanced: 60–62 grams coffee
Stronger: 65–67 grams coffee
Milder: 55–58 grams coffee
Use a medium-coarse to coarse grind, water around 195–205°F (90–96°C), and a starting steep time of approximately 4–5 minutes.
You don’t have to hit these measurements perfectly. The goal is to establish a dependable starting recipe and then adjust it according to your taste.
☕ My Starting Recipe for a 34 oz French Press
For a balanced pot, I’d start with:
60 grams of freshly ground coffee
About 1,000 grams (1 liter) of water
Medium-coarse grind
Water around 200°F
4–5 minutes of steeping
This gives you a ratio of approximately 1:16.7, which falls comfortably within a useful range for French press brewing.
If you want to follow a precise 1:16 ratio with a full liter of water, you’d use:
62.5 grams of coffee per 1,000 grams of water
There’s no practical need to obsess over that half gram, though. Somewhere around 60–63 grams gives you an excellent place to begin.
📏 Why 34 oz Is Essentially a 1-Liter French Press
A 34-fluid-ounce French press holds approximately 1 liter.
That’s convenient because coffee ratios are especially easy to calculate using metric measurements. One liter of water is 1,000 milliliters and weighs approximately 1,000 grams for everyday brewing purposes.
At a 1:16 ratio:
1,000 ÷ 16 = 62.5 grams of coffee
At a stronger 1:15 ratio:
1,000 ÷ 15 = 66.7 grams of coffee
And at a lighter 1:17 ratio:
1,000 ÷ 17 = 58.8 grams of coffee
That gives us a very useful range of approximately 59–67 grams of coffee, depending on how strong you like your brew.
🧮 34 oz French Press Ratio Chart
| Strength | Coffee | Water | Approx. Ratio |
|---|---|---|---|
| Mild | 59 g | 1,000 g | 1:17 |
| Balanced | 62.5 g | 1,000 g | 1:16 |
| Strong | 66.7 g | 1,000 g | 1:15 |
| Very strong | 71 g | 1,000 g | 1:14 |
I’d begin around 60–63 grams before experimenting with the stronger recipes.
Remember that stronger isn’t automatically better. Ideally, you want enough coffee to produce the concentration you enjoy without masking the flavors of the beans.
🥄 How Many Tablespoons of Coffee for a 34 oz French Press?
If you don’t have a scale, you can measure coffee by volume, but tablespoons are much less precise.
The weight of a tablespoon of coffee varies according to the beans, roast, grind size and how full the spoon is. This makes it difficult to give one tablespoon measurement that will consistently equal 60–65 grams.
As a rough starting point, you may need somewhere around 10–12 tablespoons of ground coffee, but consider that an approximation rather than a formula.
For consistently good French press coffee, a small digital kitchen scale is worth using. Measuring 62 grams today and 62 grams tomorrow is much more reliable than trying to reproduce the same collection of scoops.
🫙 Does a 34 oz French Press Really Make 8 Cups?
This is one of the most confusing things about buying a French press.
A 34 oz French press is frequently marketed as an 8-cup French press, but it won’t produce eight conventional 8-ounce cups of coffee.
If you divide 34 ounces by 8 ounces, you get:
34 ÷ 8 = 4.25
So 34 ounces represents a little more than four 8-ounce cups before accounting for grounds, practical fill level and coffee retained in the press.
The “8-cup” designation used with many French presses is based on much smaller coffee-cup measurements.
That’s why I recommend ignoring the advertised number of cups when calculating your coffee ratio. Use the brewer’s capacity in ounces or milliliters instead.
👥 How Many People Does a 34 oz French Press Serve?
That depends entirely on the size of everyone’s coffee.
A full 34 oz press can theoretically provide about:
Four 8-ounce servings
Three roughly 10–11-ounce servings
Two very large servings
In actual use, you may get somewhat less than the brewer’s stated maximum capacity because the grounds take up room and some liquid remains behind.
For two coffee drinkers, however, a 34 oz French press is a very practical size. It provides enough coffee for generous servings without requiring an enormous brewer.
🪨 What Grind Size Should You Use?
Start with a medium-coarse to coarse grind.
French press coffee remains in contact with the grounds throughout the steep, so it generally uses a coarser grind than you’d use for many drip brewing methods.
If the grind is extremely fine, you may notice excessive sediment, bitterness or difficulty pushing down the plunger.
If it’s extremely coarse and the coffee tastes weak, hollow or sour, try grinding somewhat finer before dramatically increasing the amount of coffee.
This is why ratio and grind size need to work together.
🌡️ What Water Temperature Should You Use?
A useful starting range is approximately 195–205°F (90–96°C).
If you don’t have a thermometer, bring your water to a boil and allow it to cool briefly before pouring.
You can experiment within that temperature range as you become familiar with your coffee. Darker roasts may taste better to you toward the lower end, while lighter coffees may benefit from hotter water.
The important thing is consistency. Once you find a combination you enjoy, repeat it.
⏱️ How Long Should a 34 oz French Press Steep?
Start with approximately 4–5 minutes.
The size of the French press doesn’t mean you need an extraordinarily long steep. A 34 oz brewer follows essentially the same brewing principles as a smaller press.
After steeping, press the plunger down slowly and evenly.
Then pour the coffee rather than leaving it sitting on the grounds for an extended period. Separating the brewed coffee from the grounds helps prevent continued extraction from changing the flavor while you drink your first cup.
💪 How to Make a 34 oz French Press Stronger
If your coffee tastes balanced but simply isn’t strong enough for you, increase the dose slightly.
For example, move from:
62 grams → 65 grams
Try that before making a dramatic change.
If you still want more intensity, work toward the 1:15 ratio, or approximately 67 grams of coffee per liter of water.
However, if your coffee is weak and sour or hollow, don’t assume you simply need more grounds. You may need a somewhat finer grind, hotter water or longer extraction.
😖 Why Does My French Press Coffee Taste Bitter?
Using too much coffee isn’t the only possible cause.
Bitterness can also result from excessively fine grounds, very hot water, prolonged extraction or the coffee itself.
If you’re already using approximately 60–65 grams of coffee per liter, I wouldn’t immediately reduce the coffee dose. First consider whether your grind or brewing process needs adjustment.
Change one variable at a time. Otherwise, it’s difficult to determine what actually improved—or ruined—the next batch.
💧 What If I Don’t Fill My 34 oz French Press Completely?
You don’t have to make an entire liter every time.
The easiest approach is to weigh however much water you want and divide that number by your preferred ratio.
For example, suppose you’re using 750 grams of water.
At 1:16:
750 ÷ 16 = about 47 grams of coffee
For 500 grams of water:
500 ÷ 16 = about 31 grams of coffee
This is much more reliable than trying to estimate what percentage of your French press you’ve filled.
📝 Easy 34 oz French Press Recipe
Here’s the version worth remembering:
60–63 grams coffee
1 liter water
Medium-coarse grind
About 200°F water
Steep for 4–5 minutes
Plunge slowly and pour
Taste it.
If you want stronger coffee, increase the coffee toward 65–67 grams. If you want something lighter, try approximately 58–59 grams.
Once you find your preferred amount, write it down. One of the best things about weighing your coffee and water is that a great pot becomes something you can intentionally reproduce.
