Million cups of coffees are consumed per day.

Millions of cups of coffees are consumed per day worldwide. Everyday, people enjoy charming cups of coffee but very few of them have full-understanding about coffee bean which are brewed to make one of the world’s most popular beverages. A coffee lover from Finland may consume up to 10 kgs of coffee per annum while an American consumes 3.1 cups of coffee per day on average.

What is a coffee bean?

“Coffee bean is the seeds of the coffee cherry; two seeds normally grow within each cherry” says a report. These beans are covered by several layers which are forced to be refined before roasting process. First of all, the nearest layer to the beans is the silver skin which is still often attached to them by a bit after roasting. Next, the silver skin is surrounded by a parchment skin continuously covered by a slimy layer and a thin layer of pulp. Finally, all of them are covered by an outer skin.

How will a coffee bean be processed?

Following that, there are two typical methods of process in which the pulp can be removed from a coffee bean: wet processing and dry processing. Coffee beans normally have green-color before roasting process. During the process, the initial green seeds transform and expand their taste, aspect and smell. Furthermore, this process also contributes to supply a longer shelf life for the upsides of the manufacturers and the consumers. Overall, the growing conditions of all types of coffee beans are the environment in which soil must be well-drained; sunlight is adequate combined with the shadows of forest surrounding. It takes at least four years for a coffee tree to get mature and yield fruit as well as beans.

First is Arabica and second is Robusta.

Nevertheless, the variety in the regions, conditions and roasting processes have a certain impact on the size, shape, color and flavor of a coffee bean. Actually, there are over ten of various types of coffee beans but there are only two official coffee beans categories which are commercially popular and cultivated for drinking. First is arabica and robusta comes second.

Arabica. Most of Arabica is grown in Latin America in which the altitudes are higher leading to a much more difficult and costly growth, whereas robusta is able to be grown in a less strict condition with lower altitudes, hotter climate but less humidity. This is resulted from twice as much as caffeine as arabica beans contained in robusta beans that enable robusta coffee beans to be immune from the attack of insects and diseases (“paralyzing or killing some of the insects that tempt to feet in it”). Unroasted arabica’s have a similar aroma to blueberries and roasted arabica’s have a sweeter, softer taste with form of sugar, fruit, berries; compared with robusta’s, which have a stronger, bitter taste with a “burnt rubbers” smell and taste.

Robusta. Robusta’s are frequently used as a complete ingredient in a blend for their deep flavor like espresso and crema creating. Otherwise, very few of them are high-qualified.

Self-roasting and storage.

For personal and private taste, a part people in the community is in favor of roasting coffee beans and enjoy coffee at home made by themselves. Hence, it is crucial to note that coffee beans should be hold in an airtight container and put in a cool, dark and dry place. In addition, some suppose to store coffee beans in the fridge or freezer, however by this way, the quality of coffee beans inside can be affected by exposure to circulating air, excess humidity and absorption rogue flavors.

To sum up, there are two main kinds of coffees. The first is arabica and robusta comes second. Each type holds its own characteristics which can be distinguished to the other. Arabica is lower in caffeine content and rich in aroma. Robusta, of course, is robust, strong in taste and higher in caffeine content. Normally, a coffee cherry will give two separate seeds. Those seeds are dried under direct sunlight and loose their moisture to become green coffee beans. After roasting, green coffee beans will become roasted coffee beans depending different roasting level. To keep roasted coffee beans always fresh, a tight and firm container (preferably with one-way valve) could be perfect to maintain coffee flavor.
