Different Sorts of Coffee—Its Enemies—Its Composition and Treatment—Methods of Making—Adulterations—Liberian Coffee—Date Coffee and other Substitutes.
There are about twenty-two species of coffee, seven of them belonging to Asia, and fifteen to Africa, where it grows in districts widely apart, as in Angola and on the shores of the Victoria Nyanza; yet, although it is so widely disseminated, and comes from so many different places, it is getting commercially dearer without any present prospect of any reduction. Its value in the market is as follows—the first being the highest, and the last the lowest in price. Mocha, Jamaica, Ceylon, Honduras, Mysore, Costa Rica, Guatemala, Brazil, New Grenada, and divers East Indian growths; and its consumption per head in Europe, ranks thus: Holland, Denmark, Germany, Belgium, Norway, Switzerland, Sweden, France, Austria, Greece, Great Britain, Italy and Russia.
Unfortunately the coffee plant has its enemies, in the shape of two fungi which have devastated the plantations of Ceylon and Mysore, one the Hemileia Vastata, and the other the Pellicularia Kolerota, whilst an insect called the coffee bug (Lecanium Coffeæ) causes great destruction, as does also the coffee, or Golunda rat. Indeed, these enemies so prevailed in Ceylon as to render coffee growing not only unprofitable, but almost impossible, so the planters took to growing tea, with the good results which we have seen.
Raw coffee has very little scent, and a bitter taste, and no one would credit it with the delicious aroma which is developed—like the tea leaf—by roasting, an operation which increases the bulk of the berry, whilst diminishing its weight. Its commercial value is in proportion to its aroma; and it is found that, by keeping the raw berry, a chemical change takes place, which very much improves inferior qualities. But this aroma is extremely volatile, and ground coffee should be kept in scrupulously air-tight cases. Indeed, so fugitive is it, that coffee to be drank in perfection should be made from berries roasted freshly every day, as is frequently done in France.
Raw coffee contains an astringent acid, which does not stain iron black, like that of tea, but green; and it also embodies Theine, or, as it is called when applied to coffee, Caffeine. This alkaloid does not exist in large quantities as in tea, i.e., the drinker of an equal number of cups of both beverages would have less of the alkaloid if coffee was drunk.
The berries, when roasted, and their flavour developed, are ground—coarse or fine according to taste, and are then ready to be made into a drink. It is here, in conjunction with the use of stale, and consequently, tasteless coffee, that we, in England, go to grief. Of coffee-making machines there are numbers; but if pure coffee is used, they might as well be dispensed with, whilst they are almost necessary if the coffee is adulterated. Another thing that our English housekeepers do not understand is, that coffee, in order to be productive of a good result, should be used large-handedly and generously, and not according to the time-honoured, grandmotherly, but parsimonious method applied to tea, of a teaspoonful for each person and one for the pot. The allowance of freshly ground coffee should be from 1½ to 2 oz. per pint of water, and any less does not make coffee, but only “water bewitched.”
With this quantity excellent coffee can be made without the aid of any machine. Warm the coffee pot, or jug, put in the coffee, and then add the water, which, as with tea, should just have come to the boil, and after standing a little time, the coffee is fit to drink. If the coffee is boiled, the extremely volatile aroma is dissipated, and its exquisite flavour lost.
But a good way of making coffee is to make it over night. Put the coffee in a jug, and pour cold water on it. The lighter particles soon get soaked and fall to the bottom. In the morning it has only to be warmed until it just boils, when it should be strained and served at once. This only applies to pure coffee.
There are too many adulterants used, and what “French Coffee” and “Coffee as in France” is made of, the Lord and their manufacturers only know. The chief of these offenders in England is the root of the succory, chicory, or wild endive (Cichorium Intybus), which, originally wild, is now extensively cultivated in England; whilst on the Continent it is very largely grown in France, Germany, Belgium, and Holland, and both home-grown and foreign chicory are largely in our market, the latter fetching the higher price. It does not taste like coffee, nor has it any aroma; but, when roasted, it gives a dark colour to water, and a bitter taste, as if a great deal of coffee had been used; and for this purpose it must have been first used in the old coffee-houses. But it is a question whether you buy pure roasted and ground chicory. In Germany it is adulterated largely with turnips and carrots, whilst Venetian red is used to give it a colour.
