Examples
“But when all of the cells are broken, great opportunity is offered for the escape of the caffeol, which is further enhanced by the slight heating which usually accompanies such fine grinding.”
“This elusive material has been variously called caffeol, caffeone, "the essential oil of coffee," etc., the terms having acquired an ambiguous and incorrect significance.”
“These compounds, which are collectively called "caffeol", vary greatly in the percentages present in different coffees, and thus are largely responsible for our ability to distinguish coffees in the cup.”
“The flavor is due largely to the volatile aromatic constituents, "caffeol," which, when isolated, have a general depressant action on the system; and the stimulation is caused by the caffein.”
“The absorbing medium is then treated with a solvent of the caffeol, and the solution is separated from the petrolatum.”
“The aromatic conglomerate, caffeol, is formed, and a considerable quantity of gas is produced, a portion of which, developing pressure in the cells of the beans, pops, or swells, them so as to increase the size of each individual bean.”
“The caffeol supplies the flavor and the aroma -- that indescribable Oriental fragrance that wooes us through the nostrils, forming one of the principal elements that make up the lure of coffee.”
“Coffee does not contain any essential oils, the aromatic constituent corresponding to essential oil in coffee being caffeol, a complex which is water-soluble, a property not possessed by any true oil.”
“However, upon extraction of ground roasted coffee with water, the caffeol shows a preferential solubility in water, and is dissolved out from the oil, going into the brew.”
“In the light of this knowledge, the grind advocated by King [384] seems to be logical, for with it -- though neither a maximum of the non-volatile extractives nor a maximum of caffeol is obtained -- an all-round maximum of cup quality is procured.”
