Decaffeinated coffee

Decaffeinated coffee
Coffee that has been processed through a chemical process to remove the majority of caffeine.

Dark
Roasting term meaning dark brown beans with a shiny surface; equivalent to espresso or French roast

Dark French Roast
A roast of coffee almost black in color with a shiny surface, thin-bodied, and bittersweet in flavor, with an overlay of burned or charcoal-like tones.

Dark Roast
Vague term; may describe any roast of coffee darker than the traditional American norm.

Dark-roasted coffee
Coffee roasted past the point of full flavor so as to bring out highly desirable burnt notes.

Decaffeination Processes
Specialty coffees are decaffeinated in the green state, currently by one of four methods. The direct solvent method involves treating the beans with solvent, which selectively unites with the caffeine and is removed from the beans by steaming. The indirect solvent or solvent-water method involves soaking the green beans in hot water, removing the caffeine from the hot water by means of a solvent, and recombining the water with the beans, which are then dried. Both processes using solvents often are called European Process or Traditional Process. The water-only method, commonly known by the proprietary name Swiss Water ProcessTM, involves the same steps, but removes the caffeine from the water by allowing it to percolate through a bed of activated charcoal. In the carbon dioxide method, which is only beginning to be established in the specialty-coffee trade, the caffeine is stripped directly from the beans by a highly compressed semi-liquid form of carbon dioxide.

Defects, Flavor Defects
Unpleasant flavor characteristics caused by problems during picking, processing (fruit removal), drying, sorting, storage, or transportation. Common defects include: excess numbers of immature or under-ripe fruit (unselective picking); inadvertent fermentation (careless processing); fermentation combined with invasion by micro-organisms, causing moldy, hard, or rioy defects (careless or moisture-interrupted drying); and contact with excessive moisture after drying, causing musty or baggy defects (careless storage and transportation).

Degassing
A natural process in which recently roasted coffee releases carbon dioxide gas, temporarily protecting the coffee from the staling impact of oxygen.

Delicate
A secondary coffee taste sensation characterized by fragile sweet-subtle sensation just past the tip of the tongue. Caused by the lowest possible combination of sugars and salts that still produce a sweet cast to the taste, a combination easily broken up by other taste sensations. Typified by a washed New Guinea arabica coffee.

Demitasse
"Half cup" in French; a half-size or three-ounce cup used primarily for espresso coffee.

Demucilage
Terms for a procedure in which the sticky fruit pulp, or mucilage, is removed from freshly picked coffee beans by scrubbing in machines. Mechanical demucilaging is gradually replacing the traditional wet processing procedure of removing mucilage by fermentation and washing.

Depth
Depth describes the resonance or sensual power behind the sensations that drive the taste of the coffee. It is a tricky and subjective term, but it tries to get at the way certain coffees open up and support their sensations with a sort of ringing, echoing power, whereas others simply present themselves to the palate and then stand pat or even fade.

Detrimental Coffee Taste Sensations
Common to natural coffees that are harsh due to bitter replacing sweet in the taste modulation. The result of sugars being ingested by the shrub as the cherries remain on the branches while drying. Range from medicinal to caustic.

Dirty
A taste that is not earthy or musty but actually grimy in flavor.

Djimah, Djimma, Jimma
A coffee from Ethiopia. Washed Djimah can be an excellent low-acid coffee. Dry-processed Djimah is a lesser coffee often exhibiting wild or medicinal taste characteristics and is not often traded as a speciality coffee.

Dominican Republic, Santo Domingo
Coffee from the Dominican Republic. High-grown Dominican coffee is a fairly rich, acidy coffee with classic Caribbean characteristics. Lower grown Dominican coffees tend to be softer and less acidy.

Doppio
A double espresso, or three to six ounces of straight espresso.

Doser
A spring-loaded device on specialized espresso grinders that dispenses single servings of ground coffee.

DP
Abbreviation for "double picked," meaning the coffee in question has been subjected to hand picking to remove imperfect beans, pebbles, and other foreign matter twice rather than once.

Drip Method
Brewing method that allows hot water to settle through a bed of ground coffee.

Dry
A coffee that finishes parched or dehydrated in the mouth, not clean. Also the opposite of sweet.

Dry-Processed Coffee, Dry Method Coffee, Natural Coffee
Coffee processed by removing the husk or fruit after the coffee fruit has been dried. When only ripe fruit is utilized and the drying is done carefully dry-processed coffee can be complex, fruity, and deeply-dimensioned. When the picking and drying are performed carelessly, as is the case with cheaper dry-processed coffees, the result is off-tasting, harsh coffee. The best and most celebrated dry-processed coffees are Yemen coffees, the Harrar coffees of Ethiopia, and the finest traditional Brazil coffees.

Dull
f it gives an impression of roundness but at the same time lacks character. Dull comes close to the meaning of flat.
