Quick Answer:
As a general rule, you need about 1 tablespoon (roughly 7 grams) of coarsely ground coffee for every 150ml (about 5oz) of water in a cafetiere. So for a standard 8-cup cafetiere holding around 1 liter of water, you’d use roughly 7 tablespoons or 60 to 70 grams of coffee.
Introduction
If you’ve just bought a cafetiere, or you’ve had one sitting in your cupboard for years but never quite trust your own measurements, you’re definitely not the only one. It’s one of those kitchen tools that looks simple but somehow leaves people second-guessing themselves every single morning. Too little coffee and you get watery, sad-tasting coffee. Too much and it turns bitter and overwhelming.
Getting how much coffee in a cafetiere right isn’t complicated once you understand the basic ratio, and that’s exactly what we’re going to sort out here.
Why the Coffee to Water Ratio Actually Matters
Before jumping into exact numbers, it helps to understand why this ratio even matters in the first place. A cafetiere, also known as a French press in some countries, works through full immersion brewing. That means the coffee grounds sit directly in the hot water for several minutes, rather than water passing through a filter quickly like in a drip machine.
Because the grounds are soaking the whole time, the amount of coffee you use has a much bigger impact on the final taste compared to other brewing methods. Too little coffee and the water can’t extract enough flavor, so you end up with something thin and a bit flat. Too much coffee, and the water pulls out more bitter compounds than you actually want, especially since it’s steeping for several minutes. This is why getting the ratio right isn’t just some fussy barista rule. It genuinely changes how your coffee tastes.
The Standard Coffee to Water Ratio for a Cafetiere
The most commonly recommended ratio is about 1 to 15, meaning one part coffee to fifteen parts water by weight. In more practical kitchen terms, that usually works out to:
- 1 tablespoon of coarse ground coffee per 150ml of water for a lighter cup
- 2 tablespoons per 150ml if you prefer it stronger
If you’re using a kitchen scale, which honestly gives you the most consistent results, aim for around 60 grams of coffee per liter of water. That’s roughly a 1 to 16 ratio, which tends to produce a well-balanced cup that isn’t too weak or too intense.
Breaking It Down by Cafetiere Size
Cafetieres come in different sizes, so it helps to know rough amounts for each. For a small 3-cup cafetiere, which usually holds about 350ml of water, you’ll want around 3 tablespoons of coffee, roughly 20 to 25 grams. For a medium 4-cup cafetiere holding around 500ml, use about 4 tablespoons, or roughly 30 to 35 grams of coffee. These numbers aren’t set in stone, they’re just a solid starting point. Your ideal amount might shift slightly depending on how strong you personally like your coffee.
Should You Measure by Scoops or by Weight
This is a fair question, since most people don’t own a kitchen scale specifically for coffee. Scoops and tablespoons work perfectly fine for everyday brewing, but they’re not always precise, since coffee beans vary in density depending on the roast and grind size.
If you want consistency every single time, weighing your coffee is genuinely the better method. A basic digital scale is cheap and takes the guesswork out completely. But if you’re just making your morning cup and don’t want to overthink it, using a tablespoon as your rough guide works absolutely fine too. Coffee doesn’t have to be complicated unless you want it to be.
Grind Size Matters Just as Much as Quantity
Here’s something a lot of beginners overlook. Even if you get the amount of coffee exactly right, using the wrong grind size can throw everything off. A cafetiere needs a coarse grind, similar in texture to sea salt or breadcrumbs. If your grind is too fine, it will slip through the mesh filter and leave your coffee gritty, plus it can extract too quickly and taste bitter. If it’s too coarse, the water won’t pull out enough flavor, leaving your coffee weak even if you used the right amount.
How Long Should You Let It Steep
Quantity and grind size aside, steeping time plays a role too. Most cafetiere coffee should steep for about 4 minutes before you press down the plunger. Less than that, and the flavor won’t fully develop. Much longer than that, and the coffee can turn bitter, especially since the grounds are still sitting in hot water the entire time. A simple trick many people use is stirring the coffee gently after about a minute of steeping, which helps break up any grounds clumping at the top and encourages more even extraction.
Common Mistakes People Make With Cafetiere Coffee
A few small mistakes tend to show up again and again, so it’s worth flagging them here. Using water that’s too hot is a common one. Water that’s actually boiling can scald the coffee and make it taste harsh. Ideally, let boiled water sit for about 30 seconds before pouring it over the grounds.
Another common mistake is leaving the coffee sitting in the cafetiere after pressing. Even after plunging, the grounds at the bottom keep affecting the coffee above them if it sits too long. It’s best to pour it out into a separate cup or thermos shortly after brewing. Lastly, using pre-ground coffee that’s too fine, often meant for drip machines instead of cafetieres, is one of the biggest reasons people end up with gritty, overly strong coffee without realizing why.
Adjusting the Ratio to Match Your Taste
Once you’re comfortable with the basic ratio, feel free to tweak it. If you generally enjoy strong coffee, lean slightly more toward the 1 to 12 ratio. If you prefer something lighter and smoother, stick closer to 1 to 16 or even 1 to 18. There’s no universal “correct” answer here beyond the general starting range. Coffee taste is personal, and the beauty of using a cafetiere is that it gives you full control over strength, unlike a lot of automatic machines that make that decision for you.
Conclusion
So, how much coffee in a cafetiere should you actually use? As a solid starting point, aim for roughly 1 tablespoon of coarse ground coffee per 150ml of water, or around 60 grams per liter if you prefer measuring by weight. From there, it’s really about adjusting slightly based on your own taste, your grind size, and how strong you like your morning cup. Once you get the ratio dialed in, making great cafetiere coffee at home becomes second nature, no fancy equipment or barista training required.

Frequently Asked Questions
For an 8-cup cafetiere holding about 1 liter of water, use around 7 to 8 tablespoons of coarse ground coffee, roughly 60 to 70 grams.
It’s best to avoid it. Fine grounds slip through the mesh filter and can make your coffee gritty and overly bitter, so stick to a coarse grind instead.
Your coffee will likely taste overly strong and bitter, since more grounds mean more extraction during the several minutes of steeping.
