Coffee, as one of the world’s most precious and traded products, is usually grown in the shape of shrubs or small trees in tropical Asia and south Africa. This plant prefers cool, humid and climate with no frost at higher elevations in tropics and subtropics. Temperature about 24C degrees, more annual rainfall with the short dry season and well-drained soil of volcanic origin will make this plant blossom. It is presented with scented white flowers which turn to deep red fruit (coffee bean) after approximately nine months. In the beginning, these young beans are green colored and after time turns to yellow as in the end will finish with red color which is a sign it is ready for harvesting. It is a small evergreen tree with smooth, elliptical leaves and knots. One of the first species of coffee that is cultivated is Arabica coffee, and it is considered as one of the best from all other coffee varieties.
Coffee is grown on small and large plantations as a very demanding and thorough crop. Red fruit as with the best quality is picked selectively and this presents a very expensive method. Each berry containing two coffee beans is separated from the skin and pulp by dry processing or wet processing which is based on local resource. Wet processing produces better quality coffee.
Quality technical expertise is needed to turn coffee beans into great quality soluble products. This also includes the great skill of testing just the right one of many samples and shapes. After all harvesting and selection come roasting beans which are followed by grinding it into a raw powder.
The Proper roasting process will give coffee its unique taste and scent. As roasting is longer coffee will be darker and stronger. Grinding gives coffee a greater surface so hot water gets its flavors more quickly and efficient. But it is very important to have just right grind in your coffee maker as well never to grind more coffee than you use for brewing. To produce much stronger coffee roast and ground are put into series of extractor cells until getting syrupy liquor. Drying this liquor in two ways produces soluble coffee. Spray drying gets most soluble coffee while freeze-drying is used to get more expensive coffee. A process called agglomeration is main factor for producing soluble coffee granules. From wetted powder, little particles stick together and result as granules. Powder or granules are put into glass jars or packs which are air extracted to keep coffee fresh for longer time.
Beans from most known coffee plantations are transported and distributed to the central and regional centers finishing in the cities with the cafes which prepare it in best possible ways for customer’s table. Best cafes are equipped with high-quality grinders. No matter if coffee comes from handy stove-top espresso maker, French press called plunger or a filter jug after all this trip coffee deserves to finish in one perfect cup of best taste and aroma.
