Filter Espresso Machines
Boiled water drips through ground coffee to fill a decanter, which can be removed to pour freshly filtered coffee into individual cups. These are fast, efficient, simple to use and more affordable than other fresh coffee solutions. The cup capacity indicates the size of the maker, and most take a reusable filter.
Espresso Pod Machines
These are more recent introductions into the market and like the Espresso Pump machines the water is sent through the coffee capsules at the correct bar pressure (15 bar+). The coffee is blended, roasted, grounded, and then hermetically sealed in capsules which stay fresh for up to 9 months. The advantages of this system are that it's an easy way to make coffee. There are no messy filter holders to clean, no spillage of coffee granules - and the coffee tastes great.
Steam Espresso Machines
Steam espresso machines work by heating water until it comes to the boil, forcing steam through ground coffee at high pressure. Better machines control the pressure and the heat of the water using a combination pump and boiler system, ensuring the coffee is not burnt and that a rich crema is produced. Steam espresso machines are generally less expensive that the pump variety and the boiling water means that the resulting liquid is hotter than that produced using the pump method.
Espresso pump machines
Espresso pump machines have a separate tank thermostatically-controlled boiler and make rich, concentrated coffee that can either be served without milk as a short cup Espresso or a long cup Americano, or with milk as Cappucino or Latte using the traditional milk frother. Tradiitonally, espresso machines offer consumers a range of coffee (depending on model) that can be used with ground coffee or easy serving espresso pods for an easier, more convenient coffee.
Bean to Cup Machines
A bean-to-cup machine is as the name suggest - literally delivering coffee from freshly ground beans, straight into your cup. At the push of a button, a bean-to-cup coffee machine grinds the coffee on demand for each cup. The ground coffee is then automatically packed tightly and the internal brewing unit pushes hot water through the coffee at professional 15 bar+ pressure. The espresso is then delivered straight into your cup, and the used coffee grinds are ejected into a tray. Some machines include a milk frother, using steam to heat and froth milk. Using the frothed milk, espresso can be transformed into cappuccino or caffe latte.
