WHY WE ROAST COFFEE BEANS

Roasting brings out the aroma and flavor that is locked inside the green coffee beans. Beans are stored green, a state in which they can be kept without loss of quality or taste.  A green bean has none of the characteristics of a roasted bean -- it’s soft and spongy to the bite and smells grassy. 

Roasting causes chemical changes to take place as the beans are rapidly brought to very high temperatures. When they reach the peak of perfection, they are quickly cooled to stop the process. Roasted beans smell like coffee, and weigh less because the moisture has been roasted out. They are crunchy to the bite, ready to be ground and brewed.

Once roasted, and degased however, they should be used as quickly as possible before the fresh roast flavor begins to diminish.
 

 

 

 

 

Light roasts

Light brown in colour, this roast is generally preferred for milder coffee varieties. There will be no oil on the surface of these beans because they are not roasted long enough for the oils to break through to the surface.

Medium roasts

This roast is medium brown in color with a stronger flavor and a non-oily surface. It’s often referred to as the American roast because it is generally preferred in the United States.

  • Breakfast

Dark roasts

This roast produces shiny black beans with an oily surface and a pronounced bitterness. The darker the roast, the less acidity will be found in the coffee beverage.  Dark roast coffees run from slightly dark to charred, and the names are often used interchangeably.

Know your roasts

In general, roasts fall into one of four colour categories — light, medium, medium-dark and dark.  

Many people assume that the strong, rich flavour of darker roasts indicates a higher level of caffeine, but the truth is that light roasts actually have a slightly higher concentration.

The perfect roast is a personal choice that is sometimes influenced by national preference or geographic location. Within the four colour categories, you are likely to find common roasts as listed below.
