Caffeine Content in 12 Oz Coffee

The caffeine content in a standard 12 oz cup of coffee can vary significantly based on several factors, including the type of coffee bean, brewing method, and the serving size. On average, a typical 12 oz cup of brewed coffee contains approximately 95 mg of caffeine. However, this number can range from about 70 mg to 140 mg depending on various factors.

Factors Influencing Caffeine Levels

Several key factors can influence the caffeine content in coffee:

  • Type of Coffee Bean: Different coffee beans have varying caffeine concentrations. For example, Robusta beans generally contain about twice as much caffeine as Arabica beans.
  • Brewing Method: The way coffee is brewed can affect its caffeine levels. Methods like espresso, cold brew, or French press can yield different caffeine concentrations.
  • Grind Size: Finer coffee grounds can lead to higher caffeine extraction during brewing, resulting in a stronger cup.
