People have been using vacuum style coffee makers to make coffee very since the mid 1800`s. The coffee maker is made by creating two types of separate glass containers that are placed on top one another. All the brewing usually takes place in the topmost container. The lower section of the vacuum style coffee maker is usually filled with cold water. What is then done is that this water is heated up to a boiling point. A siphon can then be used to remove the hot water from the lower section of the vacuum style coffee maker. This passes through the grounds of coffee and into the top section. Coffee then moves back into the lower section while the grounds remain on top. This way coffee is instantly available when you remove the top section. Most people usually opt for the vacuum style brewing of coffee rather than choosing drip coffee brewing in order to avoid the taste of drip coffee paper filters.
The java is brewed by placing the coffee and water together leaving to brew for a few minutes then depressing the plunger to trap the grounds at the bottom of the container. Because the grounds remain in direct contact with the brewing water and the grounds are filtered from the water via a mesh instead of a paper filter java brewed with the French press captures more of the brews flavor and essential oils most of these are generally trapped in the paper or wire filters we use in the drip method of brewing. Because the used grounds remain in the drink after brewing French pressed coffee should be served immediately so as to not become bitter. A typical 8-cup French press is considered expired after 20 - 25 minutes as there is no warmer plate as in many makers.
