From Prof. Mott’s Chart on the Composition, Digestibility, and Nutritive Value of Food.
Two of the most important points suggested by a study of tea are the few adulterations and the great difference between different varieties, comparing weight and bulk. Some kinds of very cheap tea are adulterated with sage and raspberry leaves, and leaves of other plants dried to simulate tea, and often flavored with essences to give an agreeable taste, but a vast amount of the tea which is sold is pure. Adulterations with chemicals are now rare, on account of the extensive cultivation of tea and the large quantities sold.
Teas vary greatly in weight,—that is, a given bulk of one tea weighs very differently from the same bulk of another. This is especially marked in the comparison of Oolong and Gunpowder.
Below are given the weights of a moderate-sized caddy-spoon of each of these teas.
| KINDS OF TEA. | Grains. | No. of spoons to the pound. |
| Oolong | 39 | 179 |
| Hyson | 66 | 106 |
| Gunpowder | 123 | 57 |
From this it appears that Gunpowder tea, bulk for bulk, is more than three times as heavy as Oolong; consequently in using it only about one third as much should be taken for a given amount of water. In making the infusion teas should be weighed, not measured, but it is not easily practicable in all households to do so; however, it can always be borne in mind that the closely rolled teas, such as Gunpowder, Young Hyson, and Japan, should be used in smaller proportion than those which are loosely rolled, like Oolong, English Breakfast, and other black teas.
There is a popular notion that green teas are dried on copper, but according to unquestionable authorities it is an erroneous one. Green teas are dried quickly so that the natural color of the leaves is preserved. Black teas are dried slowly for many hours until a sort of fermentation sets in, which causes the difference in color, as pickings from the same plant may, in the process of curing, become either green or black tea, according to the method employed. Also, different varieties of tea may be made from the same branch by difference of treatment in curing, the aromatic flavors, which did not exist in the leaves before, being produced by the drying. Different varieties or kinds of tea are also made from the same plant by gathering the leaves at different ages.
Black tea should be black, but not dead black,—rather of a grayish hue. No red leaves should be mixed with it. It should be regular in appearance, each leaf with a uniform twist, that is, in all except the “broken” teas. The leaves of tea are gathered four times a year by hand, and the finest kind is made from the tender young buds. Young Hyson is made from the early buds of April, and is noted for its mild, delicate flavor.
The principle most to be avoided in tea is the tannin, which in any considerable quantity is injurious to health. It dissolves easily when tea is either steeped for a length of time, or boiled. The important point, therefore, is not to make tea more than a few minutes before it is to be drunk, and not to boil it.
The principal kinds of tea in common use are Oolong, Japan, English Breakfast, Imperial, Gunpowder, and Young Hyson. Gunpowder, Japan, Young Hyson, and Imperial are green teas; the others are black.
To Prepare Tea.
1 Teaspoon of tea.
1 Cup of boiling water.
Fill a cup with boiling water, and let it stand a minute, or until the cup is heated through. Then empty it, put the teaspoon of tea into a tea-ball, place it in the hot cup, and pour on the boiling water slowly until it is full, leaving the tea-ball in for three minutes. This will give you a delicious and fragrant drink. If there is not a tea-ball at hand, use a small strainer, holding it so that the tea is under water for the required time.
The same principle is to be followed in making a pot of tea, except that the time of steeping should be somewhat longer. Scald the pot, which should be either of silver, granite-ware, or earthenware, not tin. Put into it the tea, in the proportion of one teaspoon to a cup of water (one half pint), and let it infuse for five minutes, but by no means allow it to boil, for boiling dissipates the aroma, and extracts the tannin, which is the injurious principle. Serve it in hot teacups with loaf-sugar and cold cream or milk. I think it is Miss Lincoln who says: “Never disgrace yourself by serving that abomination, boiled lukewarm tea in a cold cup.”
Water for tea should be fresh, and soft water—that is, water which is free from lime—is to be preferred; by taking one teaspoon of tea and a cup of water as the unit, any amount may be made; for instance, for a pot of tea for five or six persons, six teaspoons of tea and a quart and a half (6 cups) of water will be required. The time of exposure to the heat is, of course, not multiplied, the same number of minutes being enough for a greater or a lesser amount.
In connection with the study of tea, it is a very interesting fact that most authorities agree as to the time of steeping. There seems to be the unanimous opinion that it should not exceed fifteen minutes. Five minutes is the usual time given for the average kinds of tea, but for the fine, pure teas from eight to ten is a wise rule to follow.
