There have been many changes in the UKs interest in coffee in the last 10 - 15 years. The need for real espresso based coffees has increased dramatically. Instant coffee out a tin or at best "Pour and Serve" filter coffee machines were the main way of providing coffee during the past thirty years. I can speak from past experiences when selling coffee machines that prepare "real bean" espresso based coffees to businesses in the food and drink sector. These days those types of business wouldnt consider anything less than a traditional Espresso machine or Bean to Cup machine. Back then the British public was really only used to "instant" type coffee and Espresso was something foreign. Businesses didnt see the need to go "foreign."
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 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.
