The French press is the simplest full-immersion brewer. No paper filters, no electricity, no special equipment — just coarse grounds, hot water, time, and a slow plunge. When done right, it produces a rich, full-bodied cup with real weight and texture.
Any French press works — glass, stainless steel, or ceramic. The key feature is a fine wire mesh plunger that separates grounds from liquid. Larger 1-litre presses are ideal for multiple cups. Rinse with hot water before brewing to pre-warm the vessel.
Coarse grind is essential. The mesh filter cannot hold back fine particles — finely ground coffee will pass through and create a gritty, over-extracted cup. Grind to the consistency of raw sugar or coarse sea salt.
Use 60-70g of coffee per litre of water. A scale ensures consistency. A timer controls steep time — the most important variable in French press brewing. Even 30 seconds makes a noticeable difference to the final cup.
Heat water to 93-96 degrees Celsius. If you do not have a temperature-controlled kettle, bring to a boil and wait 30-45 seconds before pouring. Too-hot water over-extracts and produces bitterness. Too-cool water under-extracts and produces sourness.
Fill the empty French press with hot water, swirl, and discard. This pre-warming step prevents the cold glass from dropping the brewing temperature significantly at the start of the steep, which would cause uneven extraction.
Add your coarsely ground coffee. For a 350ml brew, use 20-24g of coffee. For a full 1-litre press, use 60-70g. Place the press on your scale and tare to zero so you can measure your water addition directly.
Pour twice the weight of water as coffee over the grounds — for 20g of coffee, pour about 40ml of water. Stir gently to saturate all the grounds and wait 30 seconds. This bloom allows CO2 to escape and begins even extraction before the main pour.
Pour the remaining water slowly and evenly over the grounds. Try to wet all the grounds uniformly. Place the lid on the press with the plunger pulled up but do not plunge yet. Start your timer for 3.5 to 4 minutes.
At 3 minutes, remove the lid and use a spoon to break the floating crust of grounds. Stir gently two or three times. Replace the lid. This step ensures grounds sink and allows the remaining 30-60 seconds of steeping to extract from all the coffee, not just the grounds below the surface.
At 4 minutes total, plunge slowly and steadily. The plunge should take 20-30 seconds of consistent pressure. If it plunges too easily, your grind is too coarse. If it requires real effort, your grind is too fine. A smooth, moderate resistance indicates correct grind size.
Pour all the brewed coffee into a serving vessel immediately after plunging. Coffee left sitting on the grounds in the press continues to extract and will become bitter and harsh within minutes. If you are not serving all the coffee at once, pour it all into a thermal carafe.
There are fine grounds in the cup making it gritty or muddy in the bottom half.
The coffee is unpleasantly bitter, astringent, or has a harsh medicinal finish.
The coffee is thin, sour, or lacks the richness expected from a French press.
