Roasting is the first crucial step when preparing the coffee beans for your favorite drink. It is the process that transforms the Green Beans to bring them a step closer to brewing format. It let’s them expand and change the color, taste, fragrance and darkness. In order to get the best taste of coffee, beans should be roasted at around the time of consumption. It ensures that the flavor and freshness of beans does not fades away after roasting.
Most of the people who like to taste the fresh coffee prefer to roast coffee at home. The coffee is considered to be exact fresh, if it is brewed 24 hours after roasting. The aroma and taste are maintained in freshly roasted coffee, which fade with longer time span. People do prefer to buy coffee that is pre-roasted as it saves time, but trust me, there is a lot of difference when you roast at home.
But don’t worry much, you can keep these beans for around a week. But ensure to store them in an air tight canister so that the flavors don’t get fade away on coming with direct contact to air.
Roasting is not a very typical process but requires some understanding about the various grades. These are classified according to the degree of heat and the time spend in roasting. The preferred method of brewing and the kind of strength you like decides your Roasting type.
