Tag: Most caffeine coffee

While a single ounce of espresso has a higher caffeine concentration than most other coffee styles, this doesn’t mean an espresso drink has the most caffeine overall. The real answer depends on several key factors, from how it’s brewed to the type of beans used.

Robusta beans can contain up to twice the caffeine of Arabica beans, offering a potent energy boost. Choosing the right coffee to wake me up involves understanding how bean type, roast, and brewing method influence the final caffeine content and overall stimulating effect.

A standard 16-ounce cold brew coffee often contains over 200mg of caffeine, making it the highest in total caffeine per serving among common preparations. However, the answer to which type of coffee brew has the most caffeine can depend on whether you measure by total serving or by concentration.
