Canned Coffee

Nami         

              Can you tell the differences between canned coffee and roasted coffee? We, likely workers in a morning before going for a work or a short break during work, buy a canned coffee from a bending machine or a convenience store. Bending machines are everywhere nowadays and it is so easy to buy a canned coffee. They got so many kinds and tastes of coffee so it is fun as well to pick one and try. But there are so many differences between these convenient canned coffees and those coffees done by the process of grinding coffee beans.

 

              Cans and instants are mass production so the tastes and flavors cannot so good. Also, they put preservatives and do other things in order to preserve long span. Thus canned coffees and instant coffees have a limit of taste. In fact, the coffee beans they are made from are different between canned coffee and roasted coffee. I would like to talk about this difference of coffee beans.

 

 

              Usually canned coffees and instant coffees use Robusta Coffee. This is also called as Coffee Canephora. 20-30 % of the amount of coffee production is this kind of coffee beans. This kind is flexible to adapt to environment so it is easy to grow them up. Its trees and leaves are quite big but the berries are small. And Robusta Coffee is strong against the insects causing damage to coffee beans and also cheap. Compared to other kinds, you can get much more coffee from same amount of coffee beans or you can make the taste of your coffee deeper because of its pyrazine organic compound. So also when you want to make a bitter one, you should mix Robusta Coffee. But u would not want to drink straight Robusta coffee because Robusta Coffee has its peculiar strong smell which makes the taste and flavor bad and stimulating. Some of coffee shops make blend coffee with around 20% of Robusta Coffee. Robusta coffee of this amount turns to be as a foil for other coffee that you blend with. And it is quite cheap so it is usually blended in canned coffee and so on for cost-down. Robusta contains much caffeine so if you prefer strong and stimulating coffee, you might want to try Robusta blended coffee.

              More common coffee bean is Coffea Arabica. It is produced all over the world as a main coffee bean. About 70% of coffee beans are Coffea Arabica. It is said to be really tasty and contains less caffeine. It contains half amount of caffeine of Robusta coffee. Usually regular coffee is made from Arabica Coffee. However, unlikely Robusta Coffe, Coffea Arabica is hard to harvest due to its cultivate location. It needs to grow at uplands of 800 ~ 2000 above sea level. Although Arabica Coffee is hard to produce, this is still produces a lot because of its deep flavor, unique bitterness, and tasty sweetness that any other kinds of coffee beans have.
