Coffee maker differences can be seen in many ways just by looking at them but there are differences that can`t be seen as well. One obvious difference that can be seen is in the types of coffee maker such as French press vacuum drip coffee maker pre-heated water espresso maker percolator and urn. Other obvious differences can be seen in size by the number of cups of coffee they make at a time. Not only the maximum but the various amounts of coffee they will make at a time. One last obvious difference is what the coffee is brewed into. These include one that has an internal thermal holding area such as in a brew station where coffee is poured by pressing a lever so it goes into a cup mug thermal mug carafe of some kind or a thermal carafe or container of some kind.
A vacuum maker brews coffee using two chambers where vapor pressure and vacuum produce brew which is clean rich and smooth compared to other brewing methods. This type of maker is also known as vac pot siphon or syphon coffee maker and was invented by Loeff of Berlin in the 1830s. These types of makers have been used for more than a century in many parts of the world. The chamber material can be pyrex metal or plastic and the filter can either be a glass rod or a screen from cloth paper or nylon. The Napier Vacuum Machine presented in 1840 was an early example of this technique. While vacuum makers are generally to complex for everyday use they were prized for producing a clear brew and were quite popular until the middle of the twentieth century.
