Vacuum Coffee Makers

Vacuum coffee makers produce an excellent, rich, smooth clean coffee taste compared to other methods of coffee brewing. Here's why:

Vacuum coffee maker operation

Vacuum coffee makers utilize two coffee brewing chambers. The vapor pressure from the hot water in the lower chamber of the vacuum coffee maker then forces the hot water into the upper chamber. The vacuum coffee maker's upper chamber contains the coffee grounds. After most of the water from the lower chamber has transferred into the upper chamber, the vacuum coffee maker's heat source is taken away. Now the vapor pressure in the lower chamber decreases greatly, and in fact, begins to draw a vacuum relative to the upper chamber.

So the coffee from the upper chamber is then drawn into the lower chamber in vacuum coffee makers. The lower chamber contains a mesh screen to capture the coffee grounds and separate them from the final brewed coffee product. A vacuum coffee maker is also sometimes called a vacuum coffee pot; the two terms are basically interchangeable based on their ultimate function of brewing excellent coffee.

Types of vacuum coffee makers

Vacuum coffee makers are available in a few different styles. The electric vacuum coffee maker has its own built in electric heat source resembling a hot plate. This hot plate provides the heat necessary to make the water hot and generate the required vapor pressure to force the water to the vacuum coffee maker chamber. Another version of vacuum coffee maker is the stovetop style. Stovetop vacuum coffee makers sit on top of a burner on a stove.

The stove's burner then furnishes the required thermal energy to make the water hot and push it up into the upper chamber for brewing. The stovetop vacuum coffee pot is often more elegant in appearance than the electric version and resembles a science project of fine glass. In fact one could probably build his or her own vacuum coffee pot out of lab grade glassware with a few beakers, some glass tube, and a bunson burner.

Vacuum coffee maker reviews

Online retailers often publish vacuum coffee maker reviews. This Bodum Santos vacuum coffee maker sold on Amazon has four out of five stars at the time of this writing. In general in the vacuum coffee maker reviews people say it takes a few tries to get used to the brewing process, a learning curve if you will, but then the coffee produced is of the finest quality. Also people caution to watch the glass parts of the unit, as they get very hot during the vacuum coffee maker brewing process.

Vacuum coffee maker grind

Often whole bean coffee is ground for use in vacuum coffee makers. However, the coffee grind used with a vacuum coffee maker must be relatively free from very fine particles, or coffee dust particles. Otherwise, the coffee dust will quickly plug up the mesh strainer in the lower chamber during the vacuum portion of the brew cycle. So generally the coffee beans should be stored in an airtight container exposed to as little oxygen as possible, and at room temperature. Frozen whole coffee beans that are ground will produce far too much dust to be used vacuum coffee makers. A normal coffee grinder, manual coffee grinder, or burr grinder may be used for grinding the whole coffee beans to then be used when brewing with vacuum coffee makers. Pre ground can also work well; however freshly ground premium whole bean coffee produces the best results. People usually prefer to use the best coffee in the world with a vacuum coffee pot to produce the finest quality coffee possible.
