French press
The French press has different names around the world.  In Australia, South Africa and Ireland it is known as a coffee plunger and coffee brewed in it is known as plunger coffee.  Its French name is cafetière à piston. Sometimes it is also called a melior (from an old brand of makers of coffee pots of this type) or a Bodum (another brand).  In the UK the device is known as a cafetière (the French word for "coffee pot").
