Focus on the roasting degree to taste the mellow and deep aroma of coffee

Coffee roasting and taste

Coffee is a popular drink. Its roasting degree and taste are important factors that determine its taste and flavor. In the coffee industry, there are various degrees of roasting, from light roasting to dark roasting, which can bring different aromas and tastes. This article will focus on the roasting degree and explore the relationship between coffee aroma and depth.

1. Light roast

Light roasting means that the coffee beans are gently heated at low temperature for a period of time, so that they become slightly yellow. This degree of roasting retains more of the original flavor and makes the coffee have a bright and fresh taste. Light roasting usually has a floral and fruity aroma and a soft acidity, and a bright and transparent color in the cup.

2. Medium focus

Medium heat tends to increase the chemical reaction on a larger range of the internal structure of the beans to produce a more complex, diverse and lasting flavor. This degree of roasting will bring a richer taste and aroma, while also reducing some acidity. The coffee beans after medium roasting are darker in color, but still retain a certain degree of original flavor.

3. Medium to deep focus

Medium to dark roast means that the coffee beans are heated to a high temperature, making them very dark and shiny on the surface. This degree of roasting produces a rich and intense taste and aroma, often with complex flavors such as cocoa, chocolate or nuts. In addition, medium to dark roast also reduces the acid content inside the coffee beans and increases bitterness.

4. Deep Black

In extreme cases, coffee beans may be over-roasted to the point of being completely black and appearing oily on the surface. This degree of roasting produces a very strong and bitter taste and aroma that may be noticeably pungent when tasted. Due to overexposure to high temperatures, the internal structure of the coffee bean has been completely destroyed, making it difficult to obtain the original flavor from it.

Summarize

The roasting degree of coffee has an important impact on its taste. Different degrees of roasting bring different aromas and tastes, making each cup of coffee have a unique flavor. Light roasting retains more original flavors, medium roasting increases complexity and richness, medium to dark roasting brings a stronger and more complex taste and aroma, while over-roasting will lead to increased bitterness and irritation. Choosing the roasting degree of coffee that suits your taste preferences is the key to tasting delicious coffee.
