I heard that lever machine is the way to go for that demand, and i have a couple of questions:
1. Is it true? The Europiccola costs about the same as the silvia (at least in my country), and I'm looking for better results than the silvia. Can I trust the Europiccola to do that (after a lot of practice of course)?
2. How come the Europiccola is not good for more than 2-3 cups in a row?
For lever machines in the La Pavoni's price range (or less) take a look at the
Ponte Vecchio Export and
Ponte Vecchio Lusso.
The short answer to question #2 is this: water in an enclosed boiler is superheated in order to produce steam for milk-based espresso drinks. The water is much too hot for espresso and scorches the coffee making it terribly bitter and unpleasant; the excessively high temperature releases ugly flavors from the bean. Therefore, machine designers use a bell-shaped hunk of brass to absorb excess heat from the superheated water. (This bell-shaped piece of brass is part of an assemblage called the 'group'.) However, after a few shots of espresso, the brass becomes saturated with heat, which greatly reduces its ability to absorb the excess heat from the water.
If the group is bolted directly to the boiler, that direct connection also allows heat to be conducted from the boiler to the group.
The heat-sinking capacity of the group is a function primarily of its mass and surface area. The more massive groups with larger surface areas take longer to become heat-saturated. If the group is not bolted directly to the boiler, the group remains cooler and is better able to absorb heat from the water.
My personal opinion is that people exaggerate the difficulty of mastering a lever, especially spring-driven levers like the Ponte Vecchio. Once you learn how a few variables interact, you are on your way to making good espresso.
BUT YOU
MUST PURCHASE A VERY GOOD STEPLESS BURR GRINDER OR A STEPPED BURR GRINDER WITH LOTS OF SETTINGS IN THE ESPRESSO RANGE. Unless you have tight control over the fineness of the grind --sometimes you need to grind coarser, sometimes more finely-- any good espresso machine will disappoint you, no matter how expensive it is and no matter if it is a lever machine or a rotary pump machine.
