Coffee normally is a must for everyone. A person may take coffee once per day. Normally people describe coffee is type of "drug", once you take it, you will like it and have one cup of coffee in a day. Coffee made off from coffee bean. According to Wikipedia, a coffee bean is the seed of the coffee plant. In a crop of coffee, a small percentage of cherries contain a single bean, instead of the usual two. This is called a peaberry. Coffee beans consist mostly of endosperm that contains 0.80-2.5% caffeine.
Coffee beans distributed into low quality beans, flat beans and peaberry.
1: center cut
2:bean (endosperm)
3: silver skin (testa, epidermis)
4: parchment (hull, endocarp)
5: pectin layer
6: pulp (mesocarp)
7: outer skin (pericarp, exocarp)

Few steps for coffee processing:
- Picking: A coffee plant usually starts to produce flowers 3–4 years after it is planted and it is from these flowers that the fruits of the plant (commonly known as coffee cherries) appear, with the first useful harvest possible around 5 years after planting.
- Wet process: In the this, the fruit covering the seeds/beans is removed before they are dried. Coffee processed by the wet method is called wet processed or washed coffee. The wet method requires the use of specific equipment and substantial quantities of water. There are Ferment-Wash Meth and Machine-assisted wet processing.
- Dry process: Dry process, also known as unwashed or natural coffee, is the oldest method of processing coffee. The entire cherry after harvest is first cleaned and then placed in the sun to dry on tables or in thin layers on patios.
(took it when I visited to the factory)
- Milling: The final steps in coffee processing involve removing the last layers of dry skin and remaining fruit residue from the now dry coffee, and cleaning and sorting it. These steps are often called dry milling to distinguish them from the steps that take place before drying, which collectively are called wet milling.
- Grading: Grading is the process of categorizing coffee beans on the basis of various criteria such as size of the bean, where and at what altitude it was grown, how it was prepared and picked, and how good it tastes, or its cup quality. Coffees also may be graded by the number of imperfections.

Other than coffee, what can we do with coffee bean? Actually in this post, after been introduced about coffee bean. I think want to show some drawings painted by coffee bean, I found it when I visited to a coffee factory at Bali, Indonesia. Is some surprised when I know that those drawings were painted by coffee bean powder. I don't know who is the artist, but at least I found that coffee beans can used to be as "color".

Actually I'm not the person who like coffee much, because for me, I think that coffee purposely is for older person who will only take coffee very often. Perhaps, I might change my mind in the coming day.-----------------------------------------------
