To answer the question,
it is a concentrated coffee beverage that is brewed
by forcing extremely hot water (but not boiling)
under very high pressure through finely ground coffee
beans. The coffee is ground so small, it's almost a
powder. It was invented in 1843 by Edward Loysel de
Santais and premiered at the Paris Exposition of
1855.
People in Milan, Italy perfected espresso in
the early 1900s. That said, it was made with steam
pressure until the mid 1940s. When the spring piston
lever machine was invented, commercial success was
huge as it pertained to espresso machines. The same
type of spring piston lever that was used in the late
1940s to make espresso is the same one that is used
today.
There are several differences between
espresso and coffee. For example, espresso is
thicker. Also, there are more dissolved solids in
espresso than there are in coffee. Furthermore, a
standard cup of coffee is 8 fluid ounces while a
standard cup of espresso is just one
ounce.
Espresso is a chemically complex fluid and
is comprised of three different parts: the body, the
heart and the crema. The latter is the most
distinguishing characteristic of espresso, and is a
reddish brown foam that floats on top. Made out of
proteins, sugars and vegetable oils, crema has
elements of foam colloid and emulsion.
Essentially, espresso is a more concentrated
form of coffee. The flavors are stronger than coffee
because of the finely grated beans and the high
pressure used during brewing. Because it is so
intense and concentrated, it mixes well with other
liquids to form different coffee based
drinks.
When mixed with milk, hot water, sugar or
chocolate, you can turn espresso into lattes, mochas,
cappuccini and macchiati. It turns out, the question
of "what is espresso?" is one that takes a longer
amount of time than expected to answer.
What is
Cappuccino?
Many people confuse
this coffee drink with a caffe latte, another
form of Italian coffee found at most coffee
houses in America. The main difference between
the two is that a caffe latte has twice the
amount of milk (usually whole milk, but one can
order it with 2 percent or even skim) and no milk
foam.
The milk foam that floats on top of a
cappuccino is what distinguishes it from most
other coffee drinks, in fact. Served
traditionally in a porcelain cup, the foam acts
as an insulator and keeps the drink hotter
longer. Additionally, the porcelain acts as
another heat retainer. Paper and glass cups tend
to allow the heat to seep out faster.
A cappuccino starts out with a shot of
espresso. The barista then steams the milk, which
is the second most important ingredient. If the
texture and temperature of the milk is wrong, the
drink won't be as good as it should
be.
When the milk is properly steamed, it
will be velvety and sweet. The barista will then
float one centimeter of the foamed milk on top of
the espresso. If one prefers their cappuccino to
have more or less milk, the order would be for a
wet or dry cappuccino, respectively.
Until the mid 1990s, Americans didn't
really enjoy cappuccino. Whether it was because
people didn't know what the drink was or because
it wasn't quite cool enough to drink isn't known.
However, when upscale coffee houses started
sprouting up en masse, more and more people began
ordering the beverage.
Traditionally, cappuccinos in Italy are
served with breakfast. Typically speaking,
Italians exclusively drink them in the morning,
although in other countries it is customary to
drink them after dinner. Hopefully, now that
you've learned the question to "what is
cappuccino", you'll be able to impress your
friends with the new found knowledge.
