Which coffee has the most caffeine?

The caffeine content in coffee can vary based on factors such as the type of coffee bean, brewing method, and serving size. However, in general, robusta coffee beans tend to have higher caffeine content compared to arabica beans.

If you're looking for coffee with the highest caffeine content, robusta beans are a good choice. Robusta beans typically contain more caffeine than arabica beans, and they are commonly used in espresso blends. Espresso, in general, tends to have a higher concentration of caffeine compared to drip coffee because it is brewed by forcing hot water through finely-ground coffee under pressure.

It's important to note that the actual caffeine content can still vary depending on factors like the specific coffee blend, roast level, and brewing time. If you're seeking a high-caffeine coffee, you might want to explore espresso or coffee blends that specifically mention the use of robusta beans. Keep in mind that consuming too much caffeine can have health effects, so it's advisable to moderate your intake based on your tolerance and preferences.
