Deep roasted coffee beans: rich aroma and mellow taste

Coffee is one of the most popular drinks in the world, and dark roasted coffee beans are famous for their rich aroma and mellow taste. In this article, we will explore the production process, characteristics and how to taste the best taste of dark roasted coffee beans.

1. Production process

Deep roasted coffee beans require longer roasting time than other types of coffee beans. Usually, these beans are placed in a high temperature environment for a long time. This process causes chemical changes inside the coffee beans, producing more complex and rich flavor substances.

Before heating begins, producers typically peel and pulp the raw, untreated coffee cherries. The remaining portion, the so-called "clean" seeds, are then heated in large rotating pans.

During the entire roasting process, the maker needs to constantly observe the color changes of the coffee beans and judge when the ideal roasting degree is reached based on experience. Generally speaking, deeply roasted coffee beans will appear darker or even black in appearance.

2. Features

Deep roasted coffee beans have a rich and complex aroma. This is because a large amount of flavor substances are produced during the long-term high-temperature heating process. These substances give coffee beans a variety of taste characteristics such as sour, bitter and sweet.

Compared with other types of coffee, dark roasted coffee beans usually have lower acidity and higher bitterness. This is because during the long heating process, the acidic substances are gradually broken down and the bitterness is enhanced.

In addition, the dark roasting process produces substances called "oils," which coat the surface of the coffee beans and give them a smooth and rich texture.

3. Tasting skills

When tasting deep roasted coffee beans, we can experience its rich aroma and mellow taste through the following steps:

First, choose a high-quality dark roasted coffee bean. This ensures that you can truly experience its characteristics.

During the brewing process, pay attention to controlling the water temperature and brewing time. Usually, use a water temperature of about 90-95 degrees Celsius and complete the brewing within 2-4 minutes.

Finally, smell the aroma of the coffee cup before tasting it. Then take a small sip and let it stay on your tongue for a while to feel its taste changes.
