Deep roasted coffee beans: rich aroma, suitable for making a variety of coffee specialties

Deep roasted coffee beans are coffee beans that have been treated with high temperature for a long time. This treatment makes the coffee beans fuller, darker in color, and have a certain degree of bitterness and burnt taste. Deep roasted coffee beans usually have a mellow and rich taste and are suitable for making various specialty coffees.

1. The difference between deep roasting and traditional roasting methods

Compared to traditional medium or light roasts, dark roasting requires higher temperatures and longer time to complete. At high temperatures, the moisture inside the coffee beans will be evaporated and the internal structure will also change. During this process, proteins and carbohydrates will react chemically to form new compounds and flavors.

The traditional method focuses on preserving the original flavor, gently removing moisture at low temperature, and maintaining the original characteristics of the coffee beans. Therefore, there is a clear difference in flavor and taste between deep roasting and traditional roasting methods.

2. Characteristics of Deep Roasted Coffee Beans

Deep roasted coffee beans usually have a darker appearance, which may even be close to black. This is because a series of chemical reactions occur inside the coffee beans under high temperature, which changes the proteins and carbohydrates and forms a substance called "vitreous".

In addition, deep roasting reduces the acidity in coffee beans and increases bitterness and burnt taste. This treatment method can make people feel a richer and fuller taste.

3. Suitable for making a variety of coffee specialties

Due to their rich, full-bodied flavor, dark roasted coffee beans are ideal for making a variety of specialty coffees. Here are a few typical examples:

a) Espresso

The espresso made from deep roasted coffee beans has a strong bitter taste and aroma. It is usually used to make espresso, such as Italian espresso, Americano, etc. This type of coffee is suitable for people who like strong taste and aroma.

b) Latte

Dark roasted coffee beans are also very suitable for making latte. Latte is a drink composed of espresso, milk and milk foam, which is characterized by a rich and layered taste. The bitterness brought by the dark roasting and the slightly sweet taste of milk blend together to form a unique and pleasant flavor.

c) Burnt Curls

In addition to traditional drinks, dark roasting can also be used to make a variety of innovative special drinks. For example, the dark roasted powder can be mixed with ice cubes, milk and other seasonings to make a cup of burnt curls. This drink has a rich coffee aroma and a slightly sweet and milky taste.

4. How to store deep roasted coffee beans

Since deeply roasted coffee beans are more fragile and easily get damp and deteriorate, you need to pay attention to the following points when storing them:

a) Try to buy whole coffee beans and grind them just before use. This will preserve the freshness and flavor of the coffee beans.

b) Store unused coffee beans in a dry, cool and well-sealed container away from direct sunlight and high temperatures.

c) When storing in the refrigerator, place the coffee beans in a sealed bag or jar and make sure to separate them from other foods to prevent the transfer of odors.

in conclusion

Deep roasting is a treatment method that makes coffee beans have a strong taste and special flavor. It is suitable for making a variety of coffee specialties, such as espresso, latte and innovative specialty drinks. When storing, it is necessary to keep it dry and sealed to maintain its freshness. Whether it is a professional barista or a home user, you can make a satisfying coffee by deep roasting beans.
