The simple answer is this: espresso is coffee brewed by forcing hot water through finely ground coffee under pressure. The NCA makes clear that espresso is defined by the method, not by a special bean.

No. Espresso is not a coffee species, a bean variety, or automatically a roast style. The NCA explicitly says it is not a type of coffee bean or even a roast. That is why the same coffee can sometimes be brewed as espresso or with another method, depending on grind size, recipe, and equipment.

The main difference is how it is brewed. Espresso uses pressure and a concentrated brewing method, while drip coffee and pour-over usually rely on gravity and a longer extraction. The NCA describes drip coffee as hot water slowly passing through ground coffee in a filter, while pour-over is a manual version where water is hand-poured through the grounds.

That is why espresso usually tastes:

• More concentrated
• More intense
• Thicker in texture
• Stronger in flavour

This depends on what “stronger” means. Espresso is usually stronger in flavour and concentration, but that does not automatically mean one serving always contains more caffeine than every mug of brewed coffee. What is clear from the NCA sources is that espresso is a more concentrated brew format, while drip coffee is a larger-volume brewing style.

Espresso tastes different because the brewing process extracts coffee in a very concentrated way. The SCA notes that brewing coffee involves a complex sequence of physical and chemical processes that shape taste and quality, and espresso’s short, pressurized extraction creates a very different cup from filter methods.

No. Although many people associate espresso with darker roasts, espresso can be made with different roast levels. The NCA’s roast guide explains that coffee roast level changes flavour, but espresso itself is still a brewing method rather than a roast category.

An espresso shot is simply a small serving of espresso. It is the concentrated result of brewing coffee under pressure, and it can be enjoyed on its own or used as the base for drinks like cappuccino, latte, and flat white. The NCA’s definition of espresso as a brewed drink by method supports this directly.

Neither is automatically better. Espresso and filter coffee are different styles. Espresso is ideal when you want concentration, body, and intensity. Filter coffee is ideal when you want a longer cup and often more openness and clarity. The NCA’s descriptions of espresso, drip, and pour-over all support this method-based difference.

It is not a bean and not a roast. It is a coffee drink made with a specific brewing method that uses pressure to produce a concentrated, intense cup. Once you understand that, espresso becomes much easier to compare with other coffee styles and much less mysterious.
