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 too
fine of a 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
The consistency of the grind is also
an important factor in the flavor of
coffee. If the grounds are uniform,
