How Much Caffeine in a Cup of Coffee? A Detailed Guide
The amount of caffeine in a cup of coffee depends on several factors, including:
*Coffee 豆 Type: Coffee beans naturally contain different amounts of caffeine. Robusta beans have a higher caffeine content than Arabica beans.
*Roast Level: Dark roast coffee beans have slightly less caffeine than light roast beans. This is because the caffeine content is slightly reduced during the roasting process.
*Grind Size: Coarser ground coffee beans produce a weaker cup of coffee with less caffeine than finer ground beans.
*Brewing Method: Different brewing methods extract different amounts of caffeine from coffee grounds. Drip coffee and French press coffee tend to have more caffeine than espresso and cold brew coffee.
*Serving Size: The size of your coffee cup also affects how much caffeine you consume. A standard 8-ounce cup of coffee contains less caffeine than a 12-ounce mug of coffee.
