ACIDITY
A tart, tangy taste experienced mainly on the tip and side of the tongue. Acidity is the liveliness in coffee.

In general, the darker the coffee is roasted the less acidity it will have.
ACIDY
A primary coffee taste sensation created as acids in the coffee combine with the sugars to increase the overall sweetness of the coffee. Found most often in washed arabica coffees grown at elevations about 4,000 feet. A term used to describe a coffee in which this desirable cup characteristic occurs. Particularly desirable in Brazils and found in most Milds. Colombians have both acid and body. An acidy flavor is sharp and pleasing to the taste as opposed to sour, sourish, or fermented. It denotes a taste that has sharpness, snap, and life, compared to a sweet, heavy, mellow flavor. Old crops are never acidy.
