Espresso Coffee
The Chemistry of Quality

Although originally an Italian product, the popularity of espresso has spread, especially in European countries of Latin origin and in recent years it has been on the increase in other markets too, above all in the USA and Japan. Its success lies in the greater satisfaction it gives to the consumer when compared with coffees prepared by other methods. Espresso is therefore the way of preparing coffee that offers higher quality to consumers.
