The flavor of coffee depends on
a variety of factors, including
the quality, freshness, and roast
of the beans, the purity of the
brew water, the cleanliness of
the brewing equipment, and the
brewing temperature. The fineness
and consistency of the grind is also
critical.
Coffee that is ground
too fine for a particular
brewing process – using
a fine espresso grind in
a drip coffee maker, for
example – will result in the
brew water over-extracting
the oils and aromatic
compounds in the
coffee, yielding a brew
that is extremely pungent
and bitter. Conversely, coffee that is
too coarsely ground for a particular
process will result in the under-
extraction of the oils and essences,
resulting in a very thin and weak
flavor. If the correct grind is used,
adding more coffee simply makes
a brew stronger without making it
excessively bitter.
The consistency of the grind is
also an important factor in the
flavor of coffee – and absolutely
critical when making great espresso.
If the grounds are uniform, equal
amounts of soluble compounds
will be extracted from each. If the
grounds vary in size, some will be
over-extracted and some will be
under-extracted, leading to extremely
poor quality. It’s not surprising that
a precision grind is mandatory for
good espresso, which is brewed
with near-boiling water under 9
bars of pressure.
Coffee grind quality is directly
related to the type of grinder
used. High speed grinders
with small burr sets are
usually not able to produce
the fineness or consistency
required for the best
espresso. They also excessively
heat the beans while grinding,
resulting in lost flavor and aroma.

Burr Grinder uses a
pair of large, commercial-style cutting
burrs to grind coffee with precision.
Frictional heating is minimized with a
gear reduction system that slows burr
rotation, and uniformity is enhanced
with a helical-gear that transports
beans to the burrs at a controlled
rate. The result is a superb grind that
makes your coffee and espresso the
best it can be.
