A French press, also known as a press pot, coffee press, coffee plunger, cafetière (UK) or сafetière à piston, is a coffee brewing device patented by Italian designer Attilio Calimani in 1929. A French press requires coffee of a coarser grind than does a drip brew coffee filter, as finer grounds will seep through the press filter and into the coffee.

Coffee is brewed by placing the ground coffee in the empty beaker and adding hot (93-96 degrees Celsius, 200-205 degrees Fahrenheit) water, in proportions of about 28 grams (1 ounce) of coffee to 450 ml (15 fluid ounces) of water, more or less to taste. After approximately four minutes the plunger is pressed to separate the grounds and hold them at the bottom of the beaker, then the coffee is poured. Coffee press users have different preferences for how long to wait before pressing the plunger, with some enthusiasts preferring to wait longer than four minutes.
