Espresso coffee was actually invented in France, before being perfected in Italy, and is today enjoyed around the world, making espresso coffee a truly universal beverage.Espresso coffee is a particular style of coffee drink and not a specific type of coffee bean.Espresso coffee is made from very finely ground coffee beans, which is tightly packed, and through which hot water is forced at pressure, to extract maximum flavour. The result is a rich, dark and extremely flavourful concentrated black coffee. On average, a single espresso coffee is usually a 7g dose of finely ground coffee, which should take 20 seconds to make a 30ml shot of espresso. The perfect espresso should then result in a fabulous shot of dark coffee which is topped off by a beautiful, 3-4 mm head of thick golden foam known as "Crema ", which is a product of the coffee&＃39;s natural oils and the source of its rich flavour and aroma. The ideal espresso should be served in cups that are dry and warm, possibly narrow in order to concentrate the espresso&＃39;s aromas and crema.
