After the initial purchase of a single serve coffee machine which ranges in price from $85 to $190 the cost per cup of coffee is much less than that of a cup of coffee from a gourmet coffeehouse. The average cost per cup of coffee is anywhere from $0.65 to $1.25 with a Keurig coffee machine. Compare this to upwards of $5.00 per cup at a coffeehouse. You will save a lot of money with the single serve coffee brewer.
Bean to cup coffee machines are relatively recent additions to the coffee machine market. The principle is to be able to duplicate more or less the range of espresso based coffees that are normally handmade on an espresso machine. All at the "Touch of a Button". As previously explained when using an espresso machine a Barista would make coffees by hand. Although not a long process it doesnt allow the Barista to prepare other food orders for example. In fast food outlets where staff do not have time to hand make a coffee or where there is limited staff training a bean to cup machine is the ideal solution. Bean to Cup machines are found in many self-serve environments such as Cafeterias Company Canteens. Bean to Cup machines are becoming popular in Offices.
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.
A wonderful traditional Italian concentrated coffee beverage is espresso. This is brewed by forcing hot water (195 degree Fahrenheit) at high pressure (90 bars) through special coffee ground to a consistency between extremely fine and powder. The appliances that are used to prepare the beverages are the espresso machines. The knowledge and efficiency in making the finest espressos is considered as a craft and the baristas who are adept in using the espresso machines professionally are regarded as skilled craftsmen in this light.
