Roasting Coffee Beans: How Do We Do It?

Roasting coffee beans is both an art and a science. Coffee can be either perfected or ruined within just a matter of seconds. It is important, as a premium coffee roaster, that you are aware of the different types of roasts and how to handle your beans. Here at Koffee Kult, we are deemed the gurus of roasting coffee beans, but how do we do it? 

The flavor you taste in your Koffee Kult cup of joe is from the roasting of the beans. The way a coffee roaster becomes an artist is when they can find the perfect balance of roasting the coffee beans to bring out the greatest flavor in them. You can consider Koffee Kult the Picasso of 100% Arabica coffee beans. 

Roasting the perfect bean relies on the specific combination of heat and time. Think about popping popcorn. Your popcorn begins to pop when it is heated to a certain temperature, as does coffee beans! The water and oxygen escaping from the bean causes the bean to pop one time. Then, carbon dioxide escapes, causing the bean to pop a second time. 

As the beans roast, Koffee Kult watches the beans change from their natural color of green through different tans and browns. In general, roasts come in four different color categories: light, medium, medium-dark, and dark roasts. During this process, coffee beans lose some of their weight from the water and carbon dioxide. Although the beans lose weight, they tend to double in size. 

  • Light roasts are light brown in color, and more mild. There should be no oil on the surface of light roast beans. 
  • Medium roasts are medium in color and have a stronger flavor than light roasts. The medium roast is the most popular in America when it comes to roasting coffee beans. 
  • Medium-dark roasts are rich and dark in color. These beans have some oil on their surface with a lightly bittersweet aftertaste. 
  • Dark roasts are shiny, dark brown, almost black beans with an oily surface. The taste of this roast is profoundly bitter. Because the roast is dark, there is less acidity in the coffee. 

After the initial roasting of the coffee beans, they are then cooled with either a vacuum system or a water mist, known as quenching. The beans are packaged into our Koffee Kult foiled bags, which allows them to release the rest of their gasses. The beans are then shipped directly to you, roasted to order, with extra TLC. 

Koffee Kult suggests consuming your premium roasted coffee beans as quickly as possible to ensure freshness and the most optimal flavor of the beans.
