RUM is an alcoholic beverage made by fermenting cane sugar, molasses, cane juice, or the scum and waste from sugar refineries and then distilling the product. It contains from 45 to 50 per cent. of alcohol, and has a disagreeable odor when it is distilled. This odor, however, is removed by storing the rum in wooden receptacles for a long period of time.
CORDIALS are beverages made by steeping fruits or herbs in brandy. Absinthe, which is barred from the United States because it contains wormwood, a very injurious substance, is a well-known cordial. Besides being extremely intoxicating, it overstimulates the heart and the stomach if taken in even comparatively small quantities.
WHISKY is an alcoholic beverage obtained by distilling fermented grain several times until it has a strength of 40 to 50 per cent. of alcohol. Then it is flavored and stored in charred casks to ripen and become mellow, after which it has a characteristic color. As can readily be understood, distilled liquors contain the highest percentage of alcohol.
STIMULATING BEVERAGES
NATURE OF STIMULATING BEVERAGES
12. STIMULATING BEVERAGES are those which contain a drug that stimulates the nervous and the circulatory system; that is, one that acts on the nerves and the circulation in such a way as to make them active and alert. Common examples of these beverages are coffee, tea, and cocoa or chocolate. If the nerves are in need of rest, it is dangerous to stimulate them with such beverages, for, as the nervous system indirectly affects all the organs of the body, the effects of this stimulation are far-reaching. The immediate effect of the stimulant in these beverages is to keep the drinker awake, thus causing sleeplessness, or temporary insomnia. If tea and coffee are used habitually and excessively, headaches, dull brains, and many nervous troubles are liable to result.
13. The stimulant that is found in the leaves of tea is known as theine; that found in coffee beans, caffeine; and that found in cacao beans, from which cocoa and chocolate are made, theobromine. Each of these stimulants is extracted by the hot liquid that is always used to make the beverage. It is taken up by the liquid so quickly that the method used to prepare the beverage makes little difference as to the amount obtained. In other words, tea made by pouring water through the leaves will contain nearly as much of the stimulant as tea made by boiling the leaves.
14. In addition to the stimulant, tea and coffee contain tannin, or tannic acid, an acid that is also obtained from the bark of certain trees and used in the tanning of animal hides in the preparation of leather. Tannin is not taken so quickly from tea and coffee by the hot liquid used in preparing the beverage as is the stimulant, so that the longer tea leaves and coffee grounds remain in the liquid, the more tannic acid will be drawn out. This fact can be detected by the bitter flavor and the puckery feeling in the mouth after drinking tea that has been allowed to remain on the leaves or coffee that has stood for some time on the grounds. Tannic acid has a decidedly bad effect on the digestion in the stomach, so that if improperly prepared tea or coffee is indulged in habitually, it may cause stomach disorders.
