Coffee beans: medium roasted and dark roasted, how much do you know?

The degree of roasting of coffee beans has an important influence on the taste and flavor of coffee. Generally speaking, coffee beans can be divided into two types: medium roasting and deep roasting. The following will introduce these two different roasting methods in detail.

Medium roast is the name of coffee beans that are heated at a relatively low temperature, usually between 210°C and 220°C. This process takes about 10 to 15 minutes to complete. Medium roasting retains the original acidity and aroma of the coffee beans, and produces a somewhat light and bright taste. Since it is not exposed to high temperatures too much, the medium roasted coffee beans also retain some natural sweetness, and have the characteristics of strong recognition and moderate tannin content.

Deep roasting is the process of processing coffee beans at a higher temperature, usually over 240°C, and lasting longer for more than 20 minutes. This process reduces the original sourness and increases bitterness, while producing a rich and heavy taste and a blackened appearance. Deeply roasted coffee beans usually have less sourness and more bitterness, and also produce a special and unique caramel flavor. This flavor is suitable for coffee lovers who like a rich taste and bitter taste.

In summary, medium roasting and dark roasting are two different ways of processing coffee beans. Medium roasting retains the original sweet and sour aroma and has a light and bright taste; while dark roasting emphasizes the rich, bitter and special caramel flavor. Which one to choose depends on personal taste preference and preference for coffee aroma and flavor expression.
