Characteristics and Roasts
A taste fault in the coffee brew giving an acrid and sour sensation on the tongue. The result of long-chained organic compounds due to excessive heat during the holding process after brewing.
A normal characteristic of arabica coffees, particularly of high-growth varieties. Some strains are sought for this particular taste (Kenya), which is influenced by the degree of roasting and does not seem to be objectively expressed by pH measurement. Experts recognize three types of acidity: 1) natural desirable: acid, 2) natural undesirable: sour, and 3) undesirable: process acidity (sometimes sought as a substitute for natural acidity but generally has a biting, puckery flavor.
A tart, tangy taste experienced mainly on the tip and side of the tongue. Acidity is the liveliness in coffee. In everyday conversation, "acidity" may sound unappealing, but in coffee terms it's actually a highly desirable quality. Not to be confused with the ph level, "palate acidity" is the brightness of flavor -- without it, coffee tastes flat and dull. All good coffees have some acidity, but to varying degree. In general, the darker the coffee is roasted the less acidity it will have.
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.
