When it comes to caffeine quantities, which beans are used makes a real difference – with Robusta beans generally having a higher caffeine content than Arabica beans. However, in most cases an espresso will have some notable differences relative to most other types of brewed coffee. Let’s explore how much caffeine you can expect in each serving and how serving size impacts your caffeine intake, remembering of course that individual countries and regions have their own methods of preparation that can also impact on the amount of caffeine per cup.
It is widely accepted that an espresso is known for its strong and concentrated flavour and typically contains more caffeine per volume than other types of brewed coffee. A single shot of espresso, which is usually about 30ml, contains approximately 63 milligrams of caffeine. On the other hand, depending on where in the world you are, 30ml of brewed coffee will generally contain about 12 milligrams of caffeine.
It's important to understand that serving size plays a big part in determining how much caffeine you get overall. So, while a 30ml espresso has a higher caffeine concentration, the smaller serving size means you're getting less caffeine per serving compared to a 300ml coffee made by a different method or piece of equipment. However, because of its smaller size, many espresso drinkers may have multiple shots in a sitting, leading to a higher overall caffeine intake.

The important thing to remember is that ultimately, there is not right or wrong, just personal preference. So whether you prefer a bold and robust flavour or a smooth and creamy blend, we encourage you to explore and experiment until you find something to suit you and your own flavour profile.
