The E.S.E. espresso machine is characterized by an extraction chamber specifically designed and shaped to optimize the quality of in-cup espresso and perfectly fit the pod. The main technical parameters of the machines, such as temperature and water pressure have been defined to ensure the consistently good quality of the espresso. These parameters are checked before any espresso machine prototype is granted permission to be marketed under the E.S.E. trademark. The same parameters are checked again once the model is placed into full scale production. All this serves to ensure constant quality.
The E.S.E. serving is a pre-measured amount of coffee – enough to yield a perfect single serving – that has been roasted, ground, weighed, tamped and sealed within two sheets of food-grade filter paper. The amount of coffee, grind size, and tamping force are defined to obtain the best possible cup of espresso. The technical characteristics of E.S.E. servings make them fit perfectly within the extraction chamber of E.S.E. espresso machines.
