What is coffee roasting? is there anything particular about roasting coffee beans that have oil?

Roasting is a process of heating that turns coffee into fragrant dark brown beans that we are familiar with and love. Roasting brings out the aroma and flavor locked inside the raw coffee beans. Beans are stored green, and in this state they can be preserved without losing quality or taste.

Mung beans don't have any of the characteristics of baked beans-they bite soft and spongy and smell like grass.

Why bake?

Baking can lead to chemical changes because beans quickly reach very high temperatures. When they reach the perfect peak, they cool quickly to stop the process. Baked beans smell like coffee and weigh less because the moisture has been roasted off. They bite brittle, ready to grind and brew.

However, once roasted coffee should be used as soon as possible before the freshly roasted taste begins to fade.

Baking is both an art and a science.

It takes years of training to become an expert baker who can "read" coffee beans and make decisions in an instant. The difference between perfectly roasted coffee and bad coffee may only take a few seconds.

Understand the baking degree

Most baking ​​ bakers have special names for their favorite baking products, and there is little standardization in the industry. This may cause some confusion when you buy, but generally speaking, barbecue comes in one of four colors-light, medium, medium dark and dark.

Many consumers believe that the rich, full-bodied flavor of deep baking indicates a high level of caffeine, but the fact is that the concentration of caffeine in light baking is actually slightly higher.

Perfect baking is a personal choice, sometimes influenced by national preferences or geographical location. Among the four color categories, you may find the common baking listed below. It's a good idea to ask before you buy it. There may be a big difference between different baking degrees.

Shallow baking

Light brown, this roasting is usually more suitable for mild coffee varieties. There will be no oil on the surface of these beans because they are not roasted long enough and the oil will not seep to the surface.

Medium baking

This barbecue is medium brown, has a stronger flavor and is not greasy on the surface. It is often called American baking because it is usually the first choice in the United States.

Medium and deep baking

This barbecue is rich and dark in color, with some oil on the surface and a slightly bittersweet aftertaste.

Deep baking

This baking produces shiny black beans with a greasy surface and a distinct bitter taste. The deeper the roasting, the lower the acidity in the coffee drink. Deep-roasted coffee ranges from slightly deep to charred, and its names are often used interchangeably-be sure to check your coffee beans before buying!
