The bitterness : This
is the flavor that one finds in endive and coffee. Most olive
varieties produce relatively bitter oils at the beginning of
the season, but their bitterness subsides as they mature. Oils
likewise loose their bitterness as they age.
The pungency : Olive oil can sometimes produce
an irritating sensation in the mouth, similar to the heat of
certain spices. This bite, like bitterness, diminishes with maturation
of the olives.
Bitterness and spiciness result from the presence of polyphenols,
which act as anti-oxidants. They help to guarantee an oil's freshness.
The mouth-feel : This term refers to an oil's
consistency, to its tactile sensation on the tongue: is it fluid,
or more viscous? The more pronounced an oil's bitterness and spice,
the more fluid it will be.
