Extraction I
nformation
Your Expo
b
ar
machine is designed to brew a proper single or double shot according to
the Specialty Coffee Association of America
’s
(SCAA) definition.
With a proper shot of
espresso
,
you extract the flavors out of the coffee that the roaster intended. If you
run
more water through than a proper shot calls for
,
you
will
extract
some
undesir
able
flavors, which will make the resulting espresso
bitter.
Whe
n brewing a shot
,
you
will notice that
at the end of the extraction the flow gets lighter
in color. This lighter color is the sign of an over extraction and will cause the bitter
flavor. For this reason
,
a Cafe Americano will taste better than a Café Crem
a.
A
Café
Americano is a proper shot of espresso mixed with hot water. The coffee is
not over
extracted. T
he
re
are
three types of coffee you can make
with the Expobar Brewtus:
espresso,
C
afé
C
rema and Café Americano
. Y
ou may find that you will not ever nee
d a
drip machine again.
