Caffeine in coffee: Coffee is a class we cannot classify because it depends on how it is made or extracted.
Technically, we can define the strength of coffee by the caffeine content of the bean. Here comes the preference of people who prefer dark roast coffee. In contrast, roasting the beans with quality coffee equipment and darkening the beans reduces its acidity and enhances the bitter taste.
Caffeine is derived from xanthine. Xanthine occurs 65% of the plants we found normally. Caffeine is most commonly found in every beverage we drink daily Most frequent consumption source of caffeine is coffee and tea.
Coffee is a mixture of chemical components of the bean. Some of these components are partially destroyed by the roasting process; however, many of these components are not. Caffeine is one of the components that is not affected by the roasting process.
Caffeine in Different Coffee Beans

Dark Roast
But the Dark Roast breaks down the beans — making it less dense and lighter.
Darker roasted coffee has a lower shelf life and is obtained in gray. It is not strong in terms of caffeine, It has a rough edge. You can think of baking and you forgot it in the toaster. You can see it as dark roast coffee. For this reason, it gives a dirtier cup.
Also, the coffee is strong and bold, but both depend on the process of making the coffee beans, regardless of its type.
Some coffee drinkers classify their coffee as strongly based on how bitter it is, but the strength of the coffee is subjective. We have different taste buds and what is strong for you may not be as intense as others. What you think is sweet may already be too bitter for some.
Light Roast
Light Roast coffee beans are lightly roasted or roasted for less time, because of this coffee beans are thicker and heavier than dark roast coffee beans.
If we dig into deep every bean of lightly roasted coffee has more caffeine content than dark roast. Light coffee roasts have 90% more water content than the dark roast coffee.
