Micro roasted coffee is a relatively new term in coffee-making circles. It refers to a process of roasting coffee beans that gets the most flavors out of them.


What is Micro Roasting?

Micro roasting refers to the process of roasting small batches of coffee beans (150 pounds or less) in a highly – controlled environment. That differs from the traditional coffee roasting process, which involves processing hundreds of pounds of coffee at a go.

Because the amount of beans roasted during micro roasting is so small, all the beans are evenly roasted. That ensures the flavor, aroma, and caffeine content is extracted from all of them to a roaster preference. The roasting process is also not rushed, ensuring the coffee beans are fully processed.


What Type of Beans are Processed Through Micro Roasting?

The beans processed through micro roasting can be single-origin beans or blends. What sets them apart is whether they are Robusta beans or Arabica beans.

Robusta beans are used to make commercial micro roasted coffee beans because they are less expensive to produce. They also have a stronger flavor and aroma than Arabica beans.

However, roasters prefer to use Arabica beans when processing micro-roasted coffee because of its interesting flavors. These beans have sugary and fruity notes reminiscent of blueberries.

Just like with regular roasts, micro-roasted coffee is categorized according to light, medium, and dark roasts.

Here are the steps to take during micro roasting.

  1. Select a great brand of green coffee beans such as Ethiopian Harrar, Sumatra coffee beans, Kenya AA coffee, Colombian coffee, or Sulawesi coffee.

You may choose a green coffee sample set that comes with different coffee beans to find the kind of flavor you prefer.

  1. Heat your roaster up to 327 degrees fahrenheit and put your green coffee beans inside. Monitor the smell of the coffee beans as they roast to identify which stage the green coffee beans are at.

During the first few minutes, the green coffee beans will turn yellow and emit an aroma like fresh-cut grass. The beans will also release some steam as their water content dissipates. That is referred to as the drying stage.

  1. Once the roaster hits 390 – 410 degrees fahrenheit, the beans will darken in color, hit the first crack, and audibly pop open.

At this stage, the sugar in the coffee beans will start to carmelize, and the aroma of the beans will get stronger as they release their oils.

If you prefer light roast coffees, stop your roasting process after the first crack when the temperature in your roaster is between 415 – 425 degrees Fahrenheit.

  1. You may continue to roast your coffee beans if you prefer a darker roast. Once the temperature hits 440 – 450 degrees fahrenheit, you’ll hear the second crack.

That is a sound that’s a bit louder than the pop you heard during the first crack. It signifies the second cracking of the coffee beans as they get darker and the sugars in them caramelize further. More coffee oils are also released from the coffee beans during the second crack.

Coffee beans roasted to the second crack have a more intense aroma than those roasted to the first crack. You can describe it as a smoky, spicy, and woody aroma.

The brew made from these coffee beans is lighter with less caffeine and a bitter-sweet taste that’s appealing to the palate. These beans can be referred to as medium to dark roast coffee beans.

  1. Roasting coffee beans beyond the 465 degrees fahrenheit mark burns off all their sugars and releases most of their remaining oils. As the coffee oils are burnt, they emit a strong charred aroma.

These beans are referred to as Dark roast coffee beans that; some people may refer to as French roast coffee. They have a slightly charred, nutty, chocolatey flavor and are best used to brew Espresso.

  1. By now, you’ve roasted your coffee beans to your satisfaction. If you are feeling adventurous, you may separate some coffee beans after each stage.

That will enable you to find out how each type of roast tastes after micro roasting. Then you can compare it to the batches of coffee you buy from the stores and see which is best.
