How much caffeine is in one serving of coffee expresso?

The caffeine content in espresso can vary depending on several factors, including the type of coffee beans used, the brewing method, and the serving size. Here are some general guidelines for the caffeine content in one serving (approximately 1 ounce or 30 milliliters) of espresso:

* Single shot espresso: contains about 63-75 milligrams of caffeine.

* Double shot espresso: contains about 126-150 milligrams of caffeine.

Espresso is known for its concentrated form and higher caffeine content compared to regular drip coffee. However, it's important to note that the serving size of espresso is much smaller than a typical cup of coffee. Therefore, the total amount of caffeine consumed may still be lower when compared to a larger serving of regular coffee.

It's worth mentioning that individual sensitivity to caffeine can vary, and some people may experience different effects from consuming the same amount of caffeine. If you're sensitive to caffeine or have any concerns, it's advisable to consult with a healthcare professional or a registered dietitian to determine the appropriate caffeine intake for you.
