Do You Just Put Coffee Grounds in a French Press?

Yes. Coarse grounds go straight into the empty carafe, and the metal mesh does the filtering. Here’s how to make French press coffee: heat water to 195°F to 205°F, use 18 grams of coffee for every 270 grams of water (a 1:15 ratio), stir, steep for 4 minutes, then press slowly and pour right away.

Knowing how to brew French press correctly comes down to a few key variables: grind size, ratio, water temperature, and timing. Most people get inconsistent results because one of them is off.

At Mōzza Roasters in Spartanburg, SC, we see this every day from home brewers trying to fix bitter or weak coffee. This guide breaks the entire process down into repeatable steps so you can get consistent results every time.

What You Need to Use a French Press

Before brewing, it helps to understand that French press is an immersion method. Coffee grounds steep directly in water, so small changes in setup have a big impact on flavor. That makes French press one of the most honest brewing methods. If your variables are off, you taste it immediately.

French Press Selection

Any standard French press works. Size matters more than material. A 3-cup press behaves differently than a 12-cup press because of heat retention and slurry volume. Glass lets heat escape faster than insulated steel, so warm a glass press before you brew.

Burr Grinder vs Pre-Ground Coffee

A burr grinder gives you the most even coarse grind, and even grounds mean less sediment slipping through the mesh. A blade grinder works in a pinch, but it leaves more fine dust. Most pre-ground coffee is ground medium for drip machines, which is too fine for French press and leads to over-extraction and sediment in the cup. No grinder at home? Aurora Blend and Nightfall Blend, for example, both come with a French press grind option at checkout.

Scale, Kettle, and Timer

Precision tools improve consistency:

• Scale for coffee and water ratio
• Kettle for temperature control
• Timer for steep accuracy

Choosing the Right Coffee for Your French Press

French press works best with full-bodied coffees that can handle immersion brewing. The metal filter lets the coffee’s natural oils into the cup, so you taste more body and texture than you would through paper. That’s why coffees with chocolate, nut, and caramel notes tend to perform best.

From our lineup, Nightfall Blend is the natural fit. It’s a medium-dark roast of Indonesian and African beans with notes of tobacco, chocolate and a touch of spice. For a more balanced cup, Aurora Blend is a medium roast with mild chocolate, honeycomb and brown sugar. Our guide to the best coffee beans for French press compares five picks.

How to Make French Press Coffee, Step by Step

The French press method is simple, but precision matters.

Step 1. Heat Your Water (and Your Press)

Heat water to 195°F to 205°F (91°C to 96°C). No thermometer? Bring it to a boil and let it sit for about 30 seconds. Pre-warm the press with a splash of hot water, then pour it out.

Step 2. Weigh and Grind the Coffee

Use a coarse grind that looks like breadcrumbs. Measure 18 grams of coffee, about 3½ level tablespoons, for a standard 8-ounce cup.

Step 3. Add Water and Start the Timer

Put the grounds in the empty press, add 270 grams of water and immediately start your timer.

Why 270 grams for an 8-ounce cup? Coffee grounds soak up about twice their weight in water, so 18 grams of coffee holds back roughly 36 grams. What pours out is close to 8 ounces.

Step 4. Stir, Steep, and Plunge

Stir gently so every ground gets wet, then set the lid on with the plunger pulled up. Let it steep for 4 minutes, then press slowly and steadily.

Step 5. Pour Immediately

Do not leave coffee sitting in the press. Pour immediately to prevent over-extraction. If you made more than you’ll drink right away, move it to a carafe or thermos.

What Is the Correct Ratio of Coffee to Water in a French Press?

Our recommended French press ratio is 1:15, meaning 1 gram of coffee for every 15 grams of water. For a standard 8-ounce cup, use 18 grams of coffee and 270 grams of water. Adjust to 1:17 for a lighter brew or 1:14 for a stronger cup.of water. For a standard 8-ounce cup, use 18 grams of coffee and 270 grams of water. Adjust to 1:17 for a lighter brew or 1:14 for a stronger cup.

French Press Ratio Cheat Sheet

Why does a full “8-cup” press only fill about three mugs? Press makers count a cup as roughly 4 ounces, so Bodum’s 8-cup Chambord holds 34 ounces, and 850 grams of water brings it up to just below the metal band. Tablespoons assume about 5 grams per level tablespoon of coarse grounds. Scoops and grinds vary, so weigh the coffee when you can.

Why 1:15 Works Best

This ratio balances extraction and body. It produces a cup that is strong enough to hold flavor but not overly bitter.

Why French Press Needs a Coarse Grind

French press requires a coarse grind that looks like sea salt. Finer grinds over-extract quickly and create sludge in the cup.

Grind Size Comparison

What Coarse Looks Like

Coarse grounds should be chunky and easy to see, not powdery. If they look like sand or table salt, they are too fine for French press.

What Are Common French Press Mistakes to Avoid?

Most French press mistakes come down to grind size, water temperature, timing, leaving coffee in the press too long, or plunging too fast. Fixing these variables immediately improves flavor and consistency without changing your coffee beans or equipment.

Mistake 1. Pre-Ground Coffee

Most pre-ground coffee is ground for drip machines, which is too fine for immersion brewing.

Mistake 2. Wrong Water Temperature

Water below 195°F under-extracts. Water above 205°F can create bitterness.

Mistake 3. Skipping the Stir

Failing to stir leaves dry pockets of coffee and uneven extraction.

Mistake 4. Leaving Coffee in the Press

Coffee continues extracting after plunging, which leads to bitterness.

Mistake 5. Plunging Too Fast

Forcing the plunger down stirs up the grounds and pushes fine particles through the mesh. Take 20 to 30 seconds. If the plunger fights you, your grind is probably too fine.

How to Adjust Your French Press for Better Coffee

Small adjustments can dramatically change the cup.

If Your Coffee Tastes Bitter

Use a coarser grind or shorten steep time slightly.

If Your Coffee Tastes Weak or Sour

Weak and sour are two different problems. Weak means too little coffee, so add a little more and move toward 1:14. Sour means the grounds didn’t extract enough, so grind a notch finer or steep 30 seconds longer.

If Your Coffee Tastes Muddy

Try the slower, settle-first approach coffee expert James Hoffmann demonstrates in his video The Ultimate French Press Technique. After the steep, break the crust of grounds on top, skim off the foam, then give the grounds several minutes to sink. Press the plunger only down to the surface of the coffee and pour gently.
