COFFEE
The coffee-tree is native to Abyssinia, but is now grown in all tropical countries. It belongs to the genus Coffea, of which there are about twenty-two species. The seeds of berries of coffee-trees constitute the coffee of commerce. Each berry contains two seeds, with exception of maleberry, which is a single round seed. In their natural state they are almost tasteless; therefore color, shape, and size determine value. Formerly, coffee was cured by exposure to the sun; but on account of warm climate and sudden rainfalls, coffee was often injured. By the new method coffee is washed, and then dried by steam heat.
In coffee plantations, trees are planted in parallel rows, from six to eight feet apart, and are pruned so as never to exceed six feet in height. Banana-trees are often grown in coffee plantations, advantage being taken of their outspreading leaves, which protect coffee-trees from direct rays of the sun. Brazil produces about two-thirds the coffee used. Central America, Java, and Arabia are also coffee centres.
Tea comes to us ready for use; coffee needs roasting. In process of roasting the seeds increase in size, but lose fifteen per cent in weight. Roasting is necessary to develop the delightful aroma and flavor. Java coffee is considered finest. Mocha commands a higher price, owing to certain acidity and sparkle, which alone is not desirable; but when combined with Java, in proportion of two parts Java to one part Mocha, the coffee best suited to average taste is made. Some people prefer Maleberry Java; so especial care is taken to have maleberries separated, that they may be sold for higher price. Old Government Java has deservedly gained a good reputation, as it is carefully inspected, and its sale controlled by Dutch government. Strange as it may seem to the consumer, all coffee sold as Java does not come from the island of Java. Any coffee, wherever grown, having same characteristics and flavor, is sold as Java. The same is true of other kinds of coffee.
The stimulating property of coffee is due to the alkaloid caffeine, together with an essential oil. Like tea, it contains
