The seeds produced by the coffee plant are the coffee beans. Though these are referred to as beans they are not really beans in the true botanical sense of the word. The coffee plant bears red or purple fruits which are also called cherries or berries of coffee and the stone that lies inside is the ‘bean’ which is the source of coffee 咖啡豆. Two stones lying with their flat sides together usually constitute the coffee bean.
It is from this bean that coffee is produced that can be used to produce a variety of coffee beverages like espresso, latte and cappuccino using the right coffee makers- espresso machines etc. It may be mentioned that a small percentage of any crop of coffee cherries contain a single bean in the cherries instead of the usual two. Such berries are called pea berries.
Coffee beans facts Some 0. 8% to 2. 5% caffeine is contained in the endosperm of the coffee seed or bean. This caffeine content gives them the characteristic flavor for which the plant is cultivated. Several species of the coffee plant are there and the seeds of each species produce coffees having slightly different tastes. Variation can be observed in the flavors of different genetic subspecies also and the coffee varietals- where the coffee plants are being cultivated.
Coffee beans are a major item of export of many countries. Coffee Arabica is the species that makes up the major portion (70-75%) of the world trade. The other important coffee species of coffee cultivated is the Coffee canephora. This is grown where the Coffee Arabica does not thrive.
Processing of coffee beans The coffee beans are processed before they are readied for use in preparing espresso, latte, cappuccino and other special coffee drinks using coffee makers- espresso machines and the like. The processing begins with the beans being removed from the coffee cherries. The fruit is then discarded or made use of as a fertilizer. The bean or seed of coffee is then ground and used in the preparation of beverages of various kinds using a coffee maker or espresso machine.
Coffee beans and espresso beans A difference between ordinary coffee beans and the espresso beans is there. The espresso beans tend to be a concoction of beans. These are almost always a relatively dark roast like a Vienna or light French roast. This is seemingly a trade secret. So, even though the formula of the blend can be discovered the exact amounts or proportions in which the constituents are to be blended cannot be easily found out.
