Coffee Bean Roasting Methods Revealed

The coffee roasting process is to process the raw beans at high temperatures to produce a special aroma and flavor. Different roasting methods will give the coffee different tastes and flavors. Let's reveal the common roasting methods of coffee beans.

Light roast

Light roasting means that the coffee beans are processed at a lower temperature for a shorter time. This method retains most of the original flavor, giving the coffee a distinct and light taste. Lightly roasted coffee beans are lighter in color and may still have some oil on the surface.

Since it has not been treated with high temperature for a long time, the acidic substances in light roasting are fully retained, so this type of coffee is usually bright, fresh, and has prominent fruit acidity. Light roasting is a good choice for those who like to taste the original flavor and pursue a refreshing taste.

Medium Roast

Medium roasting means that the coffee beans are processed at a higher temperature for a suitable time. This method allows the oil inside the coffee beans to begin to seep out, and the surface presents a certain degree of oiliness. The coffee beans after medium roasting are darker in color, but still retain some of the original flavor.

After medium roasting, the acidic substances are reduced compared to light roasting, but a certain degree of sourness is still retained. At the same time, more complex compounds and aroma substances are produced during the high temperature treatment process, giving the coffee a rich and balanced taste. This type of coffee is usually soft, sweet, and balanced.

Dark roast

Deep roasting means processing coffee beans at a relatively high temperature for a relatively long time. This method releases a large amount of oil inside the coffee beans, and the surface is completely covered with a layer of smooth and shiny black oil.

Due to long-term high-temperature treatment, the acidic substances in deep roasting almost completely disappear, and a large amount of bitterness and caramel compounds are produced. This type of coffee usually has the characteristics of richness, bitterness, caramel, etc.

Special baking method

In addition to the common roasting methods mentioned above, there are some special roasting methods that can bring different flavors to coffee. For example, Italian deep roasting (Italian RoaST) is a method of processing coffee beans to a very dark color or even close to black, making the coffee have a rich and strong taste.

Cold Brew is a method of making a drink by soaking coarsely ground or whole coffee beans in cold water for several hours and then filtering them out. This method makes less bitterness and sourness dissolved in the coffee, and retains more sweetness and aroma.
