How much caffeine in a cup of coffee?

The amount of caffeine in a cup of coffee can vary depending on several factors, including the type of coffee bean, the brewing method, and the serving size. On average, a 8 oz (240 ml) cup of brewed coffee contains about 95mg of caffeine. However, some coffee beans can have higher levels of caffeine, and some brewing methods can extract more caffeine from the beans.

For example, Arabica beans generally have less caffeine compared to Robusta beans. A 8 oz (240ml) cup of coffee made with Arabica beans contains about 60mg of caffeine, while a cup made with Robusta beans contains about 90mg of caffeine. Additionally, espresso typically has more caffeine per ounce than drip coffee, with about 64mg of caffeine per fluid ounce, while a brewed coffee has about 12mg of caffeine per fluid ounce.

It’s also important to note that many coffee shops and cafes serve larger cups than 8 oz (240ml), for example a 16 oz (480ml) cup of coffee can have almost double the amount of caffeine. Moreover, some coffee shops and cafes offer specialty drinks like lattes or cappuccinos that contain added ingredients such as chocolate or caramel syrups, which can affect the overall caffeine content.

It’s a good idea to check the labels or ask the barista for the caffeine content of the coffee you are ordering if you are sensitive to caffeine or trying to limit your intake. It’s also a good idea to monitor your own caffeine intake, as too much caffeine can lead to side effects such as insomnia, jitteriness, and increased heart rate.
