Coffee Bean Roasting: The Difference Between Medium and Dark

The difference between medium roast and dark roast

The degree of roasting of coffee beans has an important impact on the taste and flavor of coffee. Medium roasting and dark roasting are two common roasting methods, which differ in time, temperature and flavor.

Medium Roast

Medium roasting means that the coffee beans are processed until the first crack is reached and the heat is stopped. This process usually requires a lower temperature and a longer time to keep the inside of the beans moist and turn the surface into a light brown color. Since it is not processed too strongly, the medium acidity will be retained and some sweetness will also be produced.

In the cup, it is characterized by a medium to bright color and a slightly oily feeling; the rich and fresh fragrance brings people a pleasant experience; the taste tends to be more acidic with some fruit or nutty aroma.

Dark roast

In contrast, deep roasting requires higher temperatures and shorter times. After the second crack, the surface of the beans will become very dark and even oily. This roasting method usually reduces acidity while increasing bitterness and a rich taste.

Deeply roasted coffee beans are dark in color and rich in oil; they have a rich and strong aroma of chocolate or roasted malt; and they taste more bitter and have a strong caramel or cocoa flavor.

Medium vs. Deep

Medium and deep roasting methods bring completely different flavor characteristics to coffee. Medium roasting retains a certain acidity and brings some fruit or nut aroma, which is suitable for people who like a fresh taste and pursue a complex experience. Deep processing reduces acidity and increases bitterness and richness, which is suitable for people who like a strong taste and a balance of bitterness and sweetness.

In addition, medium roasting can better highlight the characteristics of the coffee beans themselves, while deep roasting emphasizes the impact of the roasting process on the flavor. Therefore, when choosing coffee, you can choose the roasting degree that suits you according to your personal taste preferences and preferences.

in conclusion

Medium roasting and deep roasting are two common and distinct ways of processing coffee beans. Medium roasting retains the acidity and some sweetness, bringing a fresh and complex experience; while deep roasting reduces the acidity and increases the bitterness and richness, which is suitable for people who like a strong taste and a balance of bitterness and sweetness. When choosing coffee, please decide the roasting degree that suits you best based on your personal taste preferences.
