Espresso and Caffeine: Keeping You Awake?

Will espresso keep you awake

Have you ever stayed up late worrying about whether that afternoon espresso will keep you awake all night? It’s a common concern among coffee drinkers, given that espresso is known to contain a higher amount of caffeine compared to other types of coffee. But the relationship between espresso and sleep is not as straightforward as you might think.


Different flavours of coffee are popular among coffee lovers, from drip coffee to instant coffee to espresso. The major reason most people consume coffee is not for the flavour but to get that sudden boost of energy. It helps their body function so they can perform daily life activities.

Espresso: A Refined Brewing Method

Espresso is strong black coffee which contains unique properties; a foamy top layer, concentrated flavour, and syrupy body. It has a relatively high amount of caffeine compared to most other caffeinated drinks.

The type of coffee bean can also affect the caffeine level. Research showed that only a limited amount of coffee can be extracted from coffee beans, and this varies depending on the type of coffee being consumed.

For instance, granulated coffee which is coarsely ground and instant coffee, which is a mixture of sugar and powdered coffee, have weaker effects compared to espresso, which is finely ground from beans.

Espresso caffeine level also depends on how finely ground the beans are. More finely grind ounces of coffee mean a more divine strong coffee flavour for you to devour.

Espresso’s Caffeine and Energy Effects

Many people believe that espresso contains the most caffeine, when in fact, espresso has less caffeine per serving than other coffee. People usually don’t have much knowledge as they think that the caffeine content of espresso is the same as that of other coffee. They don’t know how fast espresso boosts your energy.

Espressos are generally well known for being highly concentrated shots of coffee, an average 1-ounce shot of it contains around 100 mg of caffeine which is enough to keep you awake for a longer period of time. It normally stays in the human body system for approximately 6-7 hours. It gives you the kickstart to start your day.

On the other hand, other caffeinated teas usually have 100 to 115 milligrams of caffeine per serving.

One of the reasons why people consume other types of coffee instead of espresso is because it is expensive compared to local store coffee.

Espresso Shots and Caffeine Consumption

A shot is a strong stimulant as it’s way stronger than your regular cup of coffee. It is the strongest non-prescription stimulant.

A single shot of espresso contains around 70-80 mg of caffeine on average while a double contains 140-150 mg of caffeine whereas 90-100mg of caffeine is found in a regular cup of coffee.

Many people rely on it to get going in the morning. It not only helps you to stay awake for a longer period of time but also gives you a sudden energy boost, which is enough for you to perform your daily chores.

Tea as a Lower-Caffeine Coffee Substitute

Most teas have only 30 to 60 milligrams of caffeine. If you find espresso makes you jittery, tea is a good substitute to get that boost.
