Coffee roasting is an art. It’s a craft that requires years of practice and experience to perfect. There are many different ways to roast coffee, and each roaster has its own style and technique. Coffee roasters take green coffee beans and turn them into the aromatic, flavorful beans we know and love.
The process of coffee roasting is a complex one that involves many different variables. The type of bean, the origin of the bean, the roast level, and the roasting method all play a role in the final flavor of the coffee. There are many different ways to roast coffee. The most common method is drum roasting, which uses a rotating drum to roast the beans evenly. Some roasters use a hot air roaster, which uses hot air to roast the beans.
The roasting process transforms the chemical and physical characteristics of the coffee bean to prepare it for consumption while allowing for the flavor of the coffee bean to change, resulting in its robust flavor and taste.
There are also roasters that use a combination of both methods. Let’s take a closer look at the different types of roasting methods.
Drum roasting is the most common type of roasting. It uses a rotating drum to roast the beans evenly. The beans are placed in the drum and heated to high temperatures. As the beans roast, they are constantly moved around so that they roast evenly. This type of roasting can be done with or without the use of oil.
Hot Air Roasting:
Hot air roasting uses hot air to roast the beans. The beans are placed in a roaster and hot air is circulated around them. This type of roasting is very efficient and results in a consistent roast. However, it can be difficult to control the roast level with this method.
Combination roasting is a combination of drum and hot air roasting. This type of roasting uses both methods to roast the beans. The beans are first roasted in a drum, then they are transferred to a hot air roaster to finish the roast. This type of roasting results in a more consistent roast than either method alone.
Now that we’ve looked at the different types of roasting methods let’s talk about roast levels.
Roast levels are determined by the amount of time the beans are roasted. The longer the beans are roasted, the darker they will become.
There are four main roast levels: light, medium, dark, and extra dark.
Light roast coffee is roasted for a shorter amount of time than dark roast coffee. The beans are heated to a lower temperature and are not allowed to develop their full flavor potential. This results in a coffee that is lighter in color and has a more delicate flavor.
Medium roast coffee, also known as “American” roast, is roasted for a longer amount of time than light roast coffee but not as long as dark roast coffee. The beans are heated to a higher temperature and develop more of their flavor potential, resulting in a coffee that is medium brown in color and has a more robust flavor.
Medium roast coffee is most commonly preferred in the United States due to the little industry standardization in roasting terminology, which can cause confusion for consumers.
While there are similar characteristics across the types of roasts, such as balancing the bean’s flavor and characteristics determined by its geographical location, medium roast coffee offers a unique flavor profile that appeals to many coffee enthusiasts.
Dark roast coffee is roasted for the longest amount of time. The beans are heated to a very high temperature and develop their full flavor potential. This results in a coffee that is dark brown in color and has a bold, intense flavor.
Extra Dark Roast:
Extra dark roast coffee is roasted for even longer than dark roast coffee. The beans are heated to a very high temperature and develop their full flavor potential. This results in a coffee that is almost black in color and has a very bold, intense flavor.
How to Use a Coffee Roaster
Now that we’ve talked about the different types of roasters and roast levels, let’s talk about how to use a roaster. There are two main types of coffee roasters: home roasters and commercial roasters.
Home roasters are small, electric appliances that can be used to roast coffee at home. They are typically less expensive than commercial roasters and are easy to use. Most home roasters can roast up to one pound of coffee at a time.
Commercial roasters are larger, more expensive appliances that are used to roast coffee commercially. They can roast large quantities of coffee at a time and are typically used by coffee shops and cafes.
