Benefits of roasting coffee
Coffee roasting is an important process that greatly contributes to improving the quality and flavor of coffee. This process transforms green coffee beans into the distinctive brown beans that we use to make delicious coffee drinks. Some of the most prominent benefits of coffee roasting are:
- Bringing out the flavours : The roasting process stimulates chemical reactions that make the coffee flavours more pronounced and complex, giving you a rich experience and a balanced taste.
- Improves aroma : Roasting releases the aromatic oils in the beans, giving the coffee a unique, appetizing aroma.
- Reduced acidity : The higher the roast, the less acidic the coffee is, making it smoother on the stomach and deeper in taste.
- Increased antioxidants : Roasted coffee contains high levels of antioxidants that help fight free radicals in the body and promote overall health.
Roasting coffee properly is an art that requires precision in temperature and timing to ensure the best taste and quality.

The importance of roasting coffee
Coffee roasting is considered one of the vital stages in the coffee industry, as it plays a fundamental role in determining the final taste and flavor. The importance of coffee roasting lies in the following:
- Stimulating aromatic flavours : During the roasting process, chemical compounds within the coffee beans react, resulting in distinct and aromatic flavours that vary depending on the degree of roasting.
- Improve quality and taste : Roasting can bring out the natural flavor of coffee or reduce bitterness or acidity, providing the perfect balance in every cup.
- Release of aromatic oils : Roasting releases the aromatic oils that remain locked inside the beans, making the coffee richer in flavor and aroma.
- Effect on texture : The texture of coffee varies based on the degree of roasting, as it becomes thicker and deeper with dark roasting, while lighter roasting is lighter in texture and more acidic.
- Increased antioxidant benefits : Roasting helps boost the antioxidant content of coffee, which helps support overall health and fight free radicals.

Types of roasting degrees
Coffee roasting degrees vary based on the time and temperature used in roasting, which greatly affects the flavor and texture of the coffee. Here are the main types of roast degrees:
- Light roasting :
- The beans are roasted for a short time, reaching the beginning of the "first pop" without continuing for long afterwards.
- Flavor: Clear acidity, fruity and floral notes, and the natural sweetness of coffee.
- Texture: Light to medium.
- Preferred for coffee lovers who love the natural flavours of the beans and their subtle details.
- Medium roast :
- Roast a little longer after the "first pop", but without reaching the "second pop".
- Flavor: Balance of acidity and sweetness, with some caramel and nutty flavors.
- Texture: Thicker than light roast, but still smooth.
- It is a popular choice and is used to prepare many types of coffee.
- Medium dark roast :
- Roasting continues for a longer period until the beans begin to "second pop", but they are not allowed to roast completely.
- Flavor: Deep, rich flavors with a slight bitterness, including notes of dark chocolate and caramel.
- Texture: Thicker and smoother.
- Preferred for those who like coffee with a more pronounced flavour and less acidity.
- Dark roast :
- The beans are roasted until the "second crack" and sometimes a little later.
- Flavor: Strong and bitter, with charred and smoky notes, and the acidity of the coffee is greatly reduced.
- Texture: Very dense with a rich mouthfeel.
- It is suitable for those who like strong and dense coffee such as espresso.
Each roast degree adds a unique experience to the drink, and choosing the perfect degree depends on individual taste preferences.
How does roasting affect the bitterness and acidity of coffee?
The coffee roasting process greatly affects both the bitterness and acidity of the coffee, due to the chemical changes that occur within the beans during roasting. Here's how roasting affects these two aspects:
1. Acidity:
- Light Roast : Light roasted coffee has a high level of natural acidity in the beans. The acidity in this case gives a fresh, fruity flavor, and brings out the original flavors of the coffee, such as floral or fruity notes. This acidity is one of the factors that attracts lovers of fresh and mild coffee.
- Medium Roast : The acidity level decreases as the roast increases, as the acidic compounds gradually begin to fade. In this type, you get a better balance between acidity and sweetness, with more complex flavors emerging, such as nutty or caramel flavors.
- Dark Roast : As roasting continues, the acidity drops significantly and the coffee becomes smoother and less intense. Charred and dark caramel flavors begin to emerge more strongly, overpowering the original acidity of the beans.
2. Gallbladder:
- Light Roast : Light roasted coffee has very little bitterness, as the beans have not yet fully developed their bitter compounds. This type has a smoother taste and less bitterness.
- Medium Roast : As the roast increases, the bitterness becomes more pronounced due to the reaction of the chemical compounds in the beans. However, the bitterness remains moderate, giving the coffee a balanced taste between bitterness and acidity.
- Dark Roast : Bitterness is significantly increased in dark roasts, as sugars are broken down and converted into more bitter compounds. Dark coffee develops a strong, bitter taste with charred notes, adding to the coffee’s intensity and depth.

How to Roast Coffee for the Best Flavors
Roasting coffee for the best flavours requires a delicate balance of time and temperature, allowing the complex flavours within the beans to develop without losing their natural characteristics. The process begins by heating the green beans in a dedicated roaster, where the beans are exposed to temperatures ranging from 180 to 250 degrees Celsius. As the temperature rises, the beans begin to “pop” which is a sign that the natural flavours are beginning to develop. For bright flavours and balanced acidity, it is best to stop roasting shortly after the first pop. For deeper, less acidic flavours, the roast can be extended beyond the “second pop”. Controlling the roasting time carefully ensures the perfect balance between bitter and sweet flavours, making every cup of coffee a unique experience.
