Do you want to buy your own espresso machine but not sure how to choose from the many espresso machines found in the stores? The first thing one needs to do is gain an understanding of how these espresso makers work so that one can ask the right questions.

Hot water – around 90 degrees centigrade, is forced under pressure through coffee grounds. The pressures can be quite high – in some cases as much as 9 bars. The finely ground coffee has oils that when extracted make a rich, flavorful, strong cup of espresso.

If the machine is already prepped – water heated and pump primed – it should be able to produce a shot within a few seconds.

Fine grinds tend to allow the water to flow faster, although how tightly packed they are has a bearing also. See this article for more details: Espresso coffee resource.

Often a darker roasted bean will end of tasting burnt or of charcoal in the final shot. You may have to use bottled or spring water depending on the water quality in your area and if a bad taste filters through to the shot. The espresso machine you pick must also be able to consistently heat the water to the same temperature every time and this needs to be around 95 degrees c.
