We, at 1st-line Equipment, LLC, want our customers
to experience true espresso-based beverages similar to those found in
specialty coffee shops. How are true espresso beverages made? They are
made with coffee beans specifically roasted and ground for espresso.
The extraordinary flavor is extracted by consistently pressurizing
fresh water at about nine bar against the coffee grind. It is this
extraction method that truly differentiates espresso-based beverages
from other coffee drinks. The pressure creates what is known as a "crema"
on top of the beverage, and this creamy golden-brown foam on top is
what holds the extraordinary flavor of espresso-based beverages.
Instead of explaining the difference with technical
specifications, it is easier to understand the design differences between
the Pump-driven and Steam-driven (non-pump driven) machines.
First, steam driven machines typically boil water
to create hot water, steam, & pressure. The boiling water (212 degrees
F, 100 degrees C) is too hot for your espresso grinds and will create
an unfavorable taste in the cup.
Second, the steam in the boiler is used to build
pressure for the extraction of flavor from the grind. We wish this technique
would work, but the pressure is greater at the beginning of the extraction
and less at the end of the extraction. This inconsistent pressure will
result in a bitter cup. Therefore, steam driven machines, by design,
make it quite impossible to enjoy a flavorful cup of espresso or cappuccino.
That is why we, at 1st-line, mostly offer pump
driven (hand or electric) pump espresso machines for the home,
office, and commercial setting. The pump creates the minimum and
consistent pressure of about nine bar needed to create the "crema"
in the espresso. The water in the pump machines do not have to
boil the water to make pressure for pushing the water through the grinds.
The end result is a better tasting espresso.
We do hope you can appreciate one of these finer
machines when you and your guests enjoy tasting perfectly extracted
espresso, cappuccino, and lattes. |
