Espresso is made from burned coffee beans. It actually has LESS caffeine than regular American roasts (they go American Light, American Medium, French Roast, Vienna Roast, Italian Roast and Espresso. The more the beans are burned, the more caffeine is released and destroyed. Anything French Roast and beyond is burned coffee, with no original coffee flavor. That’s why Starbucks etc cover up the flavor with milk and sugars. And why triple shots have about the same amount of caffeine as a single cup of Folgers.
