The fineness of the coffee
grinds has a huge effect on the flavor that it produces with finer
grinding producing a more intense and full flavor. An even grind
will produce the best tasting coffee, as it provides for the even
extraction of the oils from the coffee. Ill-proportion coffee grinds
will lead to an inconsistent cup of coffee as it can cause your
coffee to over-extract or under-extract. Over-extracted coffee has a
bitter taste and an overly pungent aroma. Under-extracted coffee, on
the other hand, will taste both weak and thin.
