The amount of caffeine in a cup of pure coffee, typically referring to brewed coffee, varies depending on the serving size. Based on standard measurements, a common cup can contain between 95 and 247 milligrams of caffeine.
Brewed coffee is made by pouring hot water over ground coffee beans. This method, often considered "regular" or "pure" coffee without added flavors or milk, has a variable caffeine content.
According to recent data:
- An 8-ounce (oz) cup of brewed coffee can contain approximately 95 to 200 milligrams (mg) of caffeine.
- A larger 12-ounce (oz) cup of brewed coffee may contain 113 to 247 milligrams (mg) of caffeine.
This variability can be influenced by factors such as the type of coffee bean used, the brewing method, and the grind size, but the ranges provided give a clear indication of typical caffeine levels in standard brewed coffee.
