Preparing Coffee
Espresso is a unique beverage whose characteristics are unlike any other. The key component is obviously the coffee, but there are many factors that contribute to its successful preparation. Coffee blend, grind coarseness and the type of machine used will all vary from cup to cup, but together they work in harmony to achieve the optimum coffee result. Espresso coffee is a true experience for the senses, but it is fully enjoyed only when the brewing technique is meticulously performed, when the barista has all elements in perfect balance.
The best espresso -- with a fine, hazel brown crema, an intense, complex aroma, and a velvety soft body -- is a reward for the senses, recognized only with practice. Brewing and tasting espresso is an art.
