French Press Coffee: Exact Ratio, Grind, and 5-Step Method

French press coffee requires four locked parameters to taste the same every time: 1:15 coffee-to-water ratio, coarse grind, 200°F water, and a 4-minute steep. Get all four right and your French press coffee is full-bodied and rich with natural oils intact. Adjust any one of them without understanding why and the cup suffers.

This guide covers the exact parameters and the 5-step method , nothing approximate, nothing vague.

French Press Coffee Parameters

The 5-Step French Press Method

The SCA Golden Cup standard targets a 1:15 to 1:17 coffee-to-water ratio and 195 to 205°F water for all brew methods. French press targets 1:15. Full immersion without a paper filter produces a naturally heavier cup. The coarse grind is non-negotiable. Fine or medium grind clogs the filter, over-extracts, and produces a bitter, gritty cup. Coarse grind , the texture of rough sea salt , is correct. See our French press beginner guide for how these parameters affect beginners differently.

Step 1 , Heat water to 200°F: bring water to a boil, then let it sit off heat for 30 seconds. No thermometer needed , this consistently lands at 200°F. Step 2 , Grind and measure: weigh 30g of coarse-ground coffee per 450ml of water. Use a scale. Volume measures are inconsistent. Step 3 , Add grounds and pour. Place the press on a scale, add grounds, pour all the water, start the timer. Step 4 , Steep without touching: do not stir, do not press early. The grounds extract evenly if left alone. Step 5 , Press and pour immediately: press slowly and steadily over 20 to 30 seconds. Pour every drop into your cup , coffee left in the press keeps extracting and turns bitter.

French press coffee retains the natural oils from the coffee bean , drip coffee removes them through the paper filter. Those oils carry body, mouthfeel, and some aromatic compounds that paper-filtered coffee loses. The result is a heavier, richer cup with more texture. It also means French press coffee contains more cafestol , a compound that raises LDL cholesterol in large amounts. For most healthy adults drinking 2 to 4 cups per day, this is not a concern. See our drip coffee machine guide for the full comparison of filtered vs unfiltered brewing.

FAQ: French Press Coffee

1:15 by weight , 1 gram of coffee per 15 grams of water. For a standard 34 oz (1L) French press, use 65g of coffee and 1,000ml of water. For a 12 oz (350ml) press, use 23g of coffee and 350ml of water. Use a scale. Volume-based measures , scoops, tablespoons , are inconsistent because grind size and bean density vary. The weight-based ratio produces the same cup regardless of grinder or bean.

Coarse , the texture of rough sea salt or coarsely cracked black pepper. This is coarser than drip and much coarser than espresso. A coarse grind slows extraction during the 4-minute steep to the correct rate. Fine grind over-extracts, produces bitterness and sediment, and clogs the mesh filter on pressing. If pressing requires significant force, the grind is too fine. See our French press beginner guide for a grind size reference chart.

4 minutes at 200°F water. This is the standard steep time for a coarse grind at the 1:15 ratio. Steeping longer than 4 minutes over-extracts and produces bitterness. Steeping less than 3 minutes under-extracts and produces a weak, flat cup. Do not stir during the steep , disturbing the grounds changes the extraction rate mid-brew. Set a timer and do not adjust until you have brewed and tasted the standard 4-minute cup.

Three causes: grind too fine, steep too long, or coffee left in the press after pressing. Fine grind is the most common culprit , it over-extracts at any steep time. Check the grind first. If it is coarse and the bitterness persists, reduce steep time to 3 minutes 30 seconds. Always pour immediately after pressing , coffee sitting against the pressed grounds keeps extracting.

Yes , if it is labeled coarse grind. Most pre-ground coffee is medium grind, which is too fine for French press and produces over-extracted, gritty results. Pre-ground coffee labeled "French press" or "coarse" is correctly sized. Fresh-ground whole bean at a coarse setting produces the best cup.
