Brewing coffee with a French press feels like a morning ritual, where each step—pouring, waiting, plunging—rewards you with a rich, full-bodied brew.

But if you’ve ever been disappointed with a cup that’s too bitter or too weak, you’re not alone.

The great news?

You can easily tweak the French press method to create your ideal cup of coffee.

This guide will walk you through the basics, and also give you tips on how to adjust each step to suit your preferences.

By the end, you’ll not only know how to brew a stellar French press coffee but also how to customize it for your perfect flavor.

What You’ll Need:

• French press
• Coarse-ground coffee beans (about the size of breadcrumbs)
• Water just off the boil
• A timer
• Stirring tool (preferably wooden or plastic)

Step 1: Choose Your Coffee and Adjust the Grind Size

It all starts with the beans.

For most people, a medium to dark roast works best with the French press, since this method brings out the bold, rich flavors from these roasts.

But if you prefer a lighter, brighter coffee, you can absolutely experiment with a light roast.

Just know that light roasts tend to be more delicate and floral, so your cup may taste more acidic or tea-like.

Grind size is crucial, no matter what roast you choose.

A coarse grind is standard because it keeps the coffee from becoming over-extracted and bitter.

Picture breadcrumbs or coarse sea salt.

However, if you’re brewing a light roast, you might want to use a slightly finer grind (just a bit closer to table salt).

Light roasts have subtler flavors, so a finer grind can help extract more brightness and nuance.

For darker roasts, stick to the coarser side to avoid any harsh bitterness.

Step 2: Fine-Tune Your Coffee-to-Water Ratio

The foundation of a perfect brew lies in the balance between coffee and water.

A good rule of thumb is the 1:15 ratio—that’s one part coffee to 15 parts water.

For a typical 32-ounce French press (4 cups), you’ll need about 55 grams of coffee, which equals roughly 8 tablespoons.

Here’s where you can experiment:

• If you prefer a stronger, more intense coffee, try a 1:12 ratio (one part coffee to 12 parts water).
• For a lighter, smoother brew, a 1:17 ratio might be just right.

If you don’t have a scale, you can always start with 1 tablespoon of coffee for every 4 ounces of water and adjust based on how strong or light you like your coffee.

Step 3: Get Your Water Temperature Right

Water temperature is another variable that affects flavor. Most experts agree that the sweet spot for French press brewing is around 200°F (93°C).

This is just below boiling—if you don’t have a thermometer, simply bring the water to a boil and let it sit for 30 seconds.

Here’s how to adjust it based on your preferences:

• For a sweeter, more rounded flavor, especially with darker roasts, go slightly cooler—around 195°F (90°C).
• For a brighter, more vibrant flavor, especially with lighter roasts, use slightly hotter water—closer to 205°F (96°C).

The key is to avoid using boiling water directly on the grounds, as this will scorch them and lead to bitter flavors.

Step 4: Bloom for Better Flavor

Once you’ve got your water ready, it’s time to “bloom” your coffee grounds.

Pour just enough water to cover the coffee, and give it a gentle stir.

This process allows trapped gases to escape from the coffee, which can improve the overall flavor extraction.

You’ll notice the coffee bubbling and rising—that’s the bloom. Let it sit for about 30 seconds before adding the rest of the water.

If you’re brewing a light roast or prefer a more complex flavor profile, you might want to bloom for 45-60 seconds to allow more flavors to open up.

Step 5: Steep and Experiment with Time

Now that the coffee grounds are fully saturated, pour in the remaining water.

The standard steeping time is 4 minutes for most French press brews.

This gives the coffee enough time to develop a rich, full flavor without becoming overly bitter.

But this is also where you can tailor your brew:

• For a lighter, more delicate cup, steep for 3 to 3.5 minutes.
• For a bolder, more intense coffee, extend the steep time to 5 or even 6 minutes. Just be careful—anything beyond 6 minutes might lead to a brew that’s too bitter or over-extracted.

Set your timer and let the magic happen.

Step 6: Break the Crust and Stir

At the end of the steep time, you’ll see a layer of coffee grounds floating on top—this is called the "crust."

Gently break it with a spoon and give it a quick stir to fully immerse all the grounds and release the aromas.

If you prefer a cleaner cup with fewer sediments, try using two spoons to scoop out the crust before plunging.

This step can help reduce the amount of coffee sludge in your final cup, especially with lighter roasts or finer grinds.

Step 7: Plunge Slowly and Serve Immediately

Now comes the most satisfying part—plunging.

Place the lid on the French press and slowly push the plunger down.

Go easy here.

If you rush, you’ll stir up the grounds too much, which can lead to a muddy cup.

A slow, steady plunge keeps everything smooth and controlled.

Once you’ve plunged, pour your coffee immediately.

Letting it sit in the French press will continue the extraction process and may make the coffee bitter.

If you’re not serving it all at once, transfer the remaining coffee to a thermal carafe to keep it fresh and flavorful.

More Tips for Tuning Your French Press Brew

• Preheat your French press: This simple step stabilizes the temperature during brewing, giving you a more consistent cup. Swirl some hot water in the press, then discard it before brewing.

• Use filtered water: Coffee is mostly water, so if your tap water tastes off, it’ll affect your coffee too. If your coffee tastes flat or "off," try switching to filtered water for a cleaner, crisper brew.

• Grind adjustment based on flavor: If your coffee tastes bitter or harsh, your grind is probably too fine. If it’s weak or sour, the grind may be too coarse. Finer grinds extract more quickly, while coarser grinds need more time to release their flavors.

• Add milk or sweetener carefully: If you like your coffee with milk, try adding a splash of heated milk to avoid cooling down the coffee too much. For sweeteners, raw sugar or a bit of honey can complement darker roasts well, while lighter roasts might benefit from something more neutral like simple syrup.

The Reward: Your Perfect French Press Brew, Every Time

The beauty of French press brewing is in its flexibility.

Whether you like your coffee bold and dark, light and fruity, or somewhere in between, the French press lets you customize the process to fit your exact preferences.

By adjusting your grind size, water temperature, coffee-to-water ratio, and steep time, you can craft a cup that’s truly your own.

So, grab your press, experiment with these variables, and enjoy a coffee experience that’s as unique as your taste. Your morning ritual is about to get a whole lot better.

Enjoy experimenting!
