A distinction must be made between the chemical process of percolation and the coffee percolator as a device. In 1880, Hanson Goodrich invented the coffee percolator. His percolator was one of the earliest coffee brewing devices to use percolation rather than infusion or decoction as its mode of extraction, and he named it accordingly.
Vacuum Brewer. Vacuum Coffee Maker brews coffee using two chambers where vapor pressure and vacuum produce coffee which is clean, crisp, rich and smooth compared to other brewing methods. This type of coffee maker is also known as vac pot, siphon or syphon coffee maker and was invented by Loeff of Berlin in the 1830s. These devices have since been used for more than a century in many parts of the world. Design and composition of the vacuum coffee maker varies. The chamber material is pyrex, metal or plastic, and the filter can either be a glass rod, or a screen made of metal, cloth, paper or nylon. The Napier Vacuum Machine, presented in 1840, was an early example of this technique.
