Analysis of coffee bean roasting degree: exploring the way to the mellow aroma of coffee

Coffee is a popular drink that attracts countless people with its unique aroma and taste. These characteristics largely depend on the degree of roasting of the coffee beans. Different degrees of roasting will bring different flavors. Let's explore them one by one from light roasting to dark roasting.

1. Light roast

Light roasting refers to heating coffee beans at a lower temperature for a shorter time. This treatment method retains the original sourness and floral and fruity aroma of the coffee beans, making the taste refreshing and bright. Light roasting is usually used to produce high-quality original ecological single-origin coffees with high yields, such as Pescia and Yirgacheffe.

2. Medium light roast

Medium light roast is closer to the traditional "medium roast" than pure light roast. It retains some of the sour and sour flavors of flowers and fruits, and adds some caramel and biscuit aromas. This roast is suitable for making mixed coffees such as lattes, which can show more layers of texture in the melting of milk.

3. Medium roast

Medium roast is between light roast and dark roast. It is relatively closer to the traditional "full roast". Medium roast retains some of the fruity and floral aroma, but also brings more sweetness and bitterness. This roast is suitable for making filter coffee or hand-brewed coffee, which can show a rich and balanced taste.

4. Medium-dark/City+ Caramel

Medium-dark/City+ Caramel is between medium and French roasts. It retains a certain acidity while adding more sweetness, bitterness, and rich chocolate and nutty flavors. This roast is suitable for espresso or black coffee, and can bring a rich and complex taste.

5. Dark roast/French roast

Dark roasting/French roasting refers to the coffee beans being heated at a higher temperature for a longer period of time. This treatment allows the sugar inside the coffee beans to be fully oxidized, producing a lot of bitterness and caramel flavor. Dark roasting is usually used to make strong and full-bodied espresso or special blended coffee, such as latte, cappuccino, etc.

Different degrees of roasting bring different flavors of coffee. Everyone has their own preferences for taste and aroma. Therefore, when choosing coffee, you can choose the appropriate degree of roasting beans according to your favorite taste. Whether it is refreshing and bright or rich and complex, you can find one that suits your taste.
