Which type of beverage is known for its caffeine content?

Coffee is well-known for its caffeine content, which is a natural stimulant that can enhance focus and alertness. The caffeine in coffee comes from the coffee beans, and its levels can vary depending on the type of coffee, how it’s brewed, and the serving size. This makes coffee a popular choice for those looking to increase their energy levels or combat fatigue.

In contrast, milk does not contain caffeine, herbal tea generally has little to no caffeine, and sparkling water is simply carbonated water and also caffeine-free. Therefore, when considering beverages typically associated with caffeine, coffee stands out as the primary option.
