Do tea leaves contain more caffeine than coffee beans do?

Here's a general comparison:

* Coffee beans: Contain about 1.5% caffeine by weight.

* Tea leaves: Contain about 3-5% caffeine by weight, but this is on a dry weight basis.

This means that while tea leaves have a higher percentage of caffeine, the actual amount of caffeine in a cup of tea is typically lower than a cup of coffee.

This is because:

* Brewing method: Coffee is typically brewed with more grounds and for a longer time, extracting more caffeine.

* Type of tea: Different types of tea have varying caffeine content. Black tea generally has more caffeine than green tea.

However, it's important to note that:

* Individual variation: Caffeine levels can vary depending on the specific type of coffee beans or tea leaves used, as well as brewing methods.

* Personal tolerance: People experience caffeine differently, and some may be more sensitive to the effects of caffeine.
