What is the difference between coffee roast levels and their impact on quality?

February 5, 2025

Let's first begin by explaining what coffee roasting is with El-Naggar Coffee: it's exposing green coffee beans to high temperatures, which causes physical and chemical changes that produce flavors and aromas. Roasting coffee means transforming green coffee beans into ready-to-drink coffee.

The difference in taste between light and dark coffee roasts

There are differences between light and dark coffee roasts in terms of coffee flavor and taste, depending on the roasting degree. Light and medium roasts are more moderate in taste, while medium-dark roasts have a stronger flavor. However, dark roasts are more bitter in terms of their roast level.

Some people also believe that the darker the roast, the more caffeine there is in the coffee. However, some studies analyzing the composition of Arabic coffee, which included determining caffeine content in light, medium, and dark roasts, found that caffeine was 1% in all types.

What are the acidity levels of coffee? And how do they affect the taste?

Some coffee lovers drink decaffeinated coffee or avoid drinking it entirely.
Others, sometimes, find that coffee causes stomach irritation or heartburn resulting from the secretion of stomach acid.

Researchers compared roasts based on acidity, and some statistics indicate that dark roasts lead to less stomach acid secretion than light and medium roasts. Therefore, dark roasts are easier and lighter on the stomach than light and medium roasts.

The difference between acidity and bitterness in coffee

The difference between acidity and bitterness in coffee depends on the water and temperature factors, which are influential in the coffee preparation method that makes the coffee bitter or acidic.

Coffee bitterness

When using a temperature of 90 degrees or above, the coffee enters the bitterness range.

Coffee acidity

When using a temperature of 89 degrees or below, the coffee enters the acidity range.

The difference between plain and spiced coffee roasts

Plain coffee is coffee without any additives, but spiced coffee has ground cardamom or other spices added to it. However, this has no relation to the degree of roasting, as roasting degrees are light, medium, and dark, and vary depending on the taste itself. The higher the roasting degree, the less caffeine in the coffee.

Arabic coffee roasting degrees

The roasting degrees in Arabic coffee do not differ from the roasting degrees in other types of coffee. The roasting degree is estimated based on the shape and color of the coffee beans.

Light roast for Arabic coffee

Coffee beans are light-colored and dry, and this type has an acidic taste.

Medium roast for Arabic coffee

Coffee beans are medium brown, delicious, and dry, and this type has a sweet and strong flavor.

Dark roast for Arabic coffee

Roasting in this type is done for a long time, which gives it its dark color, a very rich flavor, and also a bitter taste.

Does roasting coffee reduce caffeine?
