Coffee - Different Types of Coffee Machines

One definition for a machine is a mechanically, electrically, or electronically operated device for performing a task. Thus, a coffee machine can, for all intents and purposes, be defined as a coffee maker or coffee grinder. These coffee machines can be simple to advanced and inexpensive to very expensive. This article will cover coffee makers that make as little as a single cup or as much as 60 cups and are inexpensive to very expensive.

The drip coffee machines are usually electric ones that heat the water and then pump it over the grounds.  However, a stove top type is still used. The water is boiled in a tea kettle and poured into a top reservoir with holes in it. A smaller container below holds the coffee grounds, usually with a filter. When the water finishes dripping through to the bottom, the coffee is ready to drink. Both the electric and stove top makers come in many brands and in a wide range of prices. The less expensive ones require a filter, while others may come with a permanent gold-coated coffee filter or other permanent filter.

Other similar coffee machines use a tube in the center to pump the water to the top where it drops back down over the coffee grounds. They are coffee percolators and coffee urns and come in varying sizes. Urns have greater serving sizes that go as high as 60 cups for home use.

Another coffee machine makes coffee by putting coffee in the bottom of a cylinder, which is usually glass. A filter the size of the inside of the cylinder is then pressed down to the bottom producing the coffee. These coffee machines have names such as French press, water press, a press pot, coffee press, coffee plunger or cafeti�re.

A common coffee machine is the espresso machine. These machines make coffee by using steam that is pumped through tightly packed finely ground coffee beans. The result of this process varies according to how the operator chooses to make it, which depends on the options available for their machine. These machines vary from one that simply pumps steam at Bar 15 pressure through a porta filter that holds ground coffee to programmable ones. Programmable machines will grind your coffee, make your espresso your way and even dispose the spent grounds and then sends a clean rinse through the machine. Some machines may have other attachments to make cappuccinos and lattes. Some machines similar to espressos use a higher pressure of 19 bars.

One of the popular coffee machines used today is a pod machine or pod brewer. These machines use pods or K-Cups, which already have the grounds in a container. The machine creates very hot water or steam. When the pod or K-Cup is inserted into the machine it creates a hole for the pressurized water or steam to go through. Some espresso machines, which were just mentioned above, also have the ability to use pods or K-Cups.

One that is not as popular as all the others is the vacuum machine. They come in many shapes and sizes, yet they are more alike than they are different. This system heats the water in the lower chamber creating a water vapor. This increases the pressure in the lower chamber and forces the water upward into the upper chamber that you add just before the water begins to rise. Brew for about 1.5 minutes then remove from heat, the gases in the lower chamber cool and draws the brewed coffee downward via suction caused by a partial vacuum that ensures accurate extraction of oils and caffeine for a cleaner unit without the bitter taste.

No matter what kind of coffee maker you use, you are using a coffee machine. There are so many choices for a coffee machine that the above review only covers the most common ones. Whatever coffee machine one chooses it should make coffee your way and in the amount you want.
