Roast Coffee Bean

  Roasting is a very important step in the coffee process and if done well,it will differentiate a certain branded coffee bean from another.Roasting transforms the chemicals and physical properties of the green coffee beans into the faimilar brown color you see in cafes.You can take a coffee bean from the same origin and vary the roasting step to produce a completely different taste some baristas roast coffee beans in their own homes or shops but most of the roasting is done in factories owned by the company because of the cast to operate and maintain such huge machinery.The following roasts are generalizations and so ultimately it is important to judge the coffee bean with your own eyes and scent!

Types of Roasts

Storing

Unroasted(Green) coffee beans are stored in sack or barrels and can be stored safely for months.However,after roasting they are more susceptible to losing their flavor and oils,It is generally believed that grinded coffee stays fresh for about two weeks.The best way to preserve the quality of the coffee beans is to buy whole beans and keep them whole as long as possible and grind them just before brewing.
