It is not only among the peasantry and the city slums that improperly made tea does its deadly work. Among the well-to-do, in all countries, it is far from being in all cases, as it is supposed to be, "the cup which cheers but not inebriates." The strong coffee-colored four-o'clock tea served in English and American homes is a gastronomic atrocity; it is bad for heart, nerves, and stomach. In the United States, in nine cases out of ten, the tea served is an inky fluid, bitter as gall, and devoid of fragrance.
When our Government forbade the importation of artificially colored teas, Consul West wrote from Japan that the planters were induced by this measure to "make greater efforts in future to improve the flavor rather than the color and the appearance" of the tea.
The Flavor is, indeed, the one thing to be considered in raising high-class tea; also, in preparing it. The art of brewing a good cup of tea consists in making it in such a way as to secure a maximum of fragrance and a minimum of the tannin, which is bad for the digestion, and the theine, which is a nerve poison. The rules for making tea may be found in any good cook book. The main points are that the water should never remain on the leaves more than from three to five minutes, and that the teapot should be thoroughly heated because it is only at the boiling point that some of the volatile properties of the leaves, on which the aroma depends, can be properly extracted. A little sugar to sweeten it is permissible; it does not alter the flavor. Milk or cream do; wherefore tea-drinkers who are epicures and like to enjoy the unique fragrance of different kinds of tea, reject them.
The commercial and gastronomic value of coffee is determined by the amount of the aromatic volatile oil which develops in the process of roasting. This fragrant oil is called caffeone. But coffee also has another active principle, an alkaloid called caffeine, which has a strong effect on the vascular and nervous systems and is used as a medicine. Now, the art of making good coffee consists in eliminating, as far as possible, the effects of the caffeine while developing those of the caffeone. To the caffeine are due the wakefulness and digestive disturbances caused by coffee; while the flavorsome caffeone produces the harmless exhilarating effects.
Coffee-roasting is a science which every housewife should study and practise; its neglect accounts for the fact that one so seldom gets a fragrant cup of coffee. The grinding should be done just before the coffee is prepared, and it should be drunk at once. Families having plenty of storage room should buy coffee by wholesale as it improves with age and yields a more mellow beverage. Dealers do not favor this storing because the beans lose weight thereby. Wash the beans before roasting them, and you will have the material for brewing a good cup of coffee.
An effort is being made in Europe to substitute for coffee and tea a beverage which, while having their refreshing effect, contains so small a proportion of the alkaloid substance as to be comparatively harmless, namely maté. In Argentina the use of the maté leaf has increased enormously in recent years, the annual consumption averaging nearly twenty pounds per person, and in Paraguay it is even as high as twenty-nine pounds per inhabitant. North Americans and Europeans have taken to it much more slowly, owing, it is said, to the crude way of preparing the leaves—the drying of them over an open fire, which gives them a smoky flavor. But it is claimed that superior methods of preparation will make maté a powerful rival of coffee and tea, all the more as it is much cheaper. A pound of it makes five times as many cups as a pound of coffee; and, unlike tea leaves, the maté leaves can be used for a second infusion without impairment of the quality.
In beverages, as in foods, Flavor is the decisive factor. The natural flavor of maté seems to be as agreeable as that of tea or coffee, but it is apt to be marred by the suggestion of smoke just referred to. If this can be eliminated, and if it is true that maté, though containing less caffeine than either tea or coffee, is even more stimulating and sustaining, then "Paraguay tea" seems destined to be the domestic beverage of the future.
