Pressopannu

Pressopannu, literally meaning “press pot” in Finnish, is the Finnish name for the French press, a coffee maker that brews by immersion and uses a movable plunger with a metal mesh filter to separate the grounds from the liquid.

Most pressopannut consist of a glass or metal carafe with a lid and a plunger assembly. The carafe typically holds about 0.35 to 1 liter of liquid, and many models feature a stainless steel frame or insulating sleeve. The metal mesh filter allows oils and some fines to pass, imparting a fuller body to the coffee.

To brew, coarsely ground coffee is combined with hot water just off the boil, usually around 92–96°C. After adding water and optional stirring, the mixture is allowed to steep for about 3–4 minutes. The plunger is then pressed slowly downward to push the grounds to the bottom, and the brewed coffee is poured.

Origin and popularity: the French press concept emerged in Europe in the early to mid-20th century and has since become common worldwide. It is associated with simple design and robust extraction.

Advantages and limits: pressopannut require no paper filters, preserve essential oils and body, and are relatively inexpensive. They require a coarser grind and a longer brew time, and can produce sediment and a fuller-bodied, sometimes bolder cup. Cleaning can be more involved than some drip methods, and glass carafes are fragile.

Maintenance: rinse after use, periodically disassemble for thorough cleaning, and remove mineral buildup with a mild vinegar solution or specialized cleaners. Replace damaged seals or screens to maintain performance.
