Factors Affecting Caffeine Content

The following factors determine the caffeine level in coffee.

Coffee beans: Arabica and Robusta
The higher-quality Arabica beans are sweeter than Robusta beans, which have higher caffeine content, strong and bitter.

The bean density changes during roasting. Lightly roasted coffee is denser than a darker roast and has more caffeine.

Serving size:
There are too many variables, depending on the beans and how the coffee is brewed. Generally, it's between 70-140mg.

Does Espresso or Black Coffee Have More Caffeine?
Technically correct but not necessarily, as the factors that determine the level of caffeine are the cup size and the coffee strength.

A cup of espresso is between 1.5oz to 2oz, but a cup of black coffee is 8oz which is the factor in the strength of the coffee.

Espresso is about 40–50mg per ounce which makes the levels of caffeine anywhere between 60 and 100mg per cup, whereas Black coffee can have between 65 and 125mg of caffeine.

Espresso offers you a concentrated volume of caffeine in coffee compared to a cup of black coffee?

An espresso is consumed quicker,  so caffeine is absorbed by the body quickly, whereas black coffee usually consumes slowly and may take up a longer duration to consume. So the caffeine intake in that scenario is like a slow drip-feed into the body.
