Coffee Jargon A to W
Let’s start with the ‘A’s
ACIDITY: Not a defect , acidity is one if the reasons the best high grown Arabica coffee beans fetch the highest prices. As a roast gets going, flavourful acids form, giving coffee life and sparkle. The lighter the roast, the more the acids are highlighted; very dark roasts destroy most acids. Not be confused with bitterness.
ADENOSINE: One of the chemicals, or neurotransmitters, the body makes to control neural activity; adenosine triggers a series of slowing effects in the body. Researchers think caffeine acts as an adenosine imposter, locking into special receptors on brain cells and fooling the body into thinking that adenosine is circulating when it is not. Caffeine thus speeds up by not slowing you down.
AGED COFFEE: Green coffee beans that have been stored in the climate, typically hot and humid ,on which they were grown, for a year or two ore even three before being shipped similar to monsooning , which takes less time, aging bean is expensive, because stocks are tied up. Aged coffee has a soft roundness many connoisseurs seek, especially for blends.
AIR QUENCHING: The cooling of roasted beans with blown air rather than with sprayed water. (see water-quenching)
ARABICA: One of the two main coffee species. Coffee Arabica is named for its original popularizes, the Arabs, who bought it to native East Africa to the Arabian Peninsula in the fifteenth century. All the delicate, prized flavours possible in coffee are found in Arabica and not robust, the other main species , although not every Arabica is fine. Arabica beans, which produce the best flavors when grown at high altitudes in semitropical climates near the equator, naturally contain about half the caffeine (an average of 1.1 percent) of robusta beans (which have an average of 2.2 percent).
