How Much Caffeine Is In A Shot Of Espresso

Espresso is an Italian origin coffee prepared when very hot, pressurized water is passed through finely-ground coffee beans and collected in a cup put below the porta-filter.

A shot is a single serving of Espresso also called, a solo shot. Pure espresso coffee is made from 1.5 ounces of hot water passed through 7 grams of finely ground coffee for around 25 seconds. Espresso has a creamy topping called, the crema. There is no definite amount of how much caffeine is in a shot of Espresso because each coffee shop and barista have their brewing styles, the type of coffee beans used, machines, and filter basket sizes.

How much caffeine in a shot of Espresso is determined by the amount of your more. The volume of servings also varies from one barista to another. But why do people always feel more impact when they take Espresso compared to other coffee brews? This could be because Espresso is taken in a few gulps while other coffee drinks are slowly sipped as you enjoy the rich flavor and sweet aroma.

How Much Caffeine Is In A Shot Of Espresso

How much caffeine is in a single shot of Espresso

The amount of caffeine contained in a single shot of Espresso varies widely depending on the type of coffee beans used, the amount of coffee used, the method used in the preparation, the amount of time taken to brew, and the number of ounces per serving. Espresso and espresso products are a generally concentrated coffee brew made by extracting the essence of roasted beans by using pressurized hot water. The question of how much caffeine is in a shot of Espresso can only be given an estimated value due to the variations in Espresso's preparation. The caffeine level in a single shot of Espresso ranges from 29 mg up to 100 mg, with an average of about 75 mg.

How much caffeine is in a double shot of Espresso

A double shot is two servings of Espresso, and it is also called Espresso Doppio. In most coffee joints, double shots are more popular, and regardless of their sizes, espresso shots are served in a demitasse (small cups), which on average hold, 2 to 3 ounces of Espresso. The amount of caffeine in double shots also varies significantly from one brand to another and the brew dimensions. But generally, for a double shot, of espresso caffeine concentrations range from 58 mg up to 185 mg within an average of about 150mg.

Which Has More Caffeine: Espresso vs. Coffee?


Espresso is not a well-understood method of coffee brewing. The technique came about as Luigi tried to look for an easy way to make a cup of coffee in a short time. His finding was made better when Achille came up with manual levers that helped pull a shot of Espresso. From the method, espressos usually have a brownish froth topping, crema, which gives them an inviting aroma.

The crema topping and fast brewing process give Espresso's a tasty flavor, a long-lasting after taste but, lower caffeine levels than other types of coffee.

There exists a widespread belief that Espresso has more caffeine than regular coffee. This could be because caffeine is a very bitter compound, and Espresso is made from dark roasts, accumulating more bitter molecules. This kind of thinking looks logical, but it is not entirely true. The bitter molecules accumulated in dark roasts are not as a result of caffeine concentrations, but bitter compounds which are generated during the intense roasting process.

Methodically, Espresso has higher caffeine levels per ounce. This is basically due to the finer grind used to make Espresso. If fine grind could be used in an automatic drip maker, you will get a bitter brew because of the long time taken by an automatic brewer.  Regular coffee has higher caffeine concentration per serving. But it is not right to measure caffeine concentration in terms of per serving because pure Espresso is served in shots which are equivalent to an ounce while a cup of regular coffee from 8 ounces to over 30 ounces.

There is an average of 75 mg caffeine concentration in one espresso serving, while one serving of regular coffee has 120 mg of caffeine. On average, a solo shot of Espresso is equivalent to two ounces. In comparison, a standard cup of regular coffee is equal to 12 ounces, which shows that regular coffee has higher caffeine concentration per cup.

When caffeine concentration is compared in terms of per ounce instead of per serving, Espresso is seen to have more significant concentrations of caffeine in it. With regular coffee, the level of caffeine keeps changing, depending on the machine used, the grind size, and the type of beans.

How Much Caffeine Is Too Much?

How Much Caffeine Is Too Much

Caffeine has its perks, and it can also lead to problems. For healthy adults, a daily intake of up to 400 mg of caffeine is considered to be safe. This is equivalent to taking four cups of ordinary coffee or five double shots of Espresso. Liquid form or powdered caffeine easily give toxic levels of caffeine. A teaspoon of powdered caffeine is equal to roughly twenty-eight cups of coffee or thirty-five double espresso shots. Scary right? Well, such amounts of caffeine intake can lead to health complications or even death.

Caffeine intake is considered safe for adults, but for children, it is risky. Teenagers and the young adults should avoid taking too much caffeine or using other drugs alongside caffeine. Some adults also experience adverse effects when they take caffeine. People under certain treatments or who are overly sensitive to caffeine could also experience unpleasant side effects.

Expectant women, those who are trying to get pregnant, and nursing mothers should not take more than 200 mg of caffeine, but they should get clear directions on caffeine intake from their respective medical practitioners.

Why many people prefer higher amounts of caffeine

It is hard to forget the experience we had with our first cup of coffee. However, some people are faced with surrendering caffeine intake because of tremors they suffer or due to other health complications, but the craving can be overwhelming. Caffeine is a psychoactive drug that influences our feelings and thinking due to the release of dopamine after we take coffee. It is a stimulant that alters our minds, accelerates our breathing, increases our pulse rate, and influences our thoughts as well as actions. People take high amounts of caffeine for multiple different reasons, which include:

  • Some of us end up taking a higher amount of caffeine simply because we enjoy the taste of coffee and coffee products. Coffee gives us the 'feel good' effect on us since it hits right into our brain's reward system.
  • Students find themselves consuming a lot of caffeine to give them the energy to get through the long nights at the study corner.
  • Others working in shifts, especially night shift workers, drink high amounts of caffeine to assist their bodies and minds cope with working during odd hours.
  • Those who undertake sporting activities or dance for longer periods, take high amounts of caffeine to enhance their endurance while performing various activities.

If you heavily bank on caffeine to energize you up and keep you going, you are not alone. Millions of people depend on caffeine to remain awake and improve concentration in their day to day activities. The more caffeine we take, the better we feel after a terrible night or a long day, and wonder how much caffeine in a shot of Espresso do we get? But, taking heavy amounts of caffeine all day long or near bedtime could also cause problems.


What Is The Reason Behind The Differences In The Amount Of Caffeine: Coffee Vs. Espresso?

We know that there is no actual measure of caffeine concentrations in the two drinks, we rely on estimates. But what causes the differences in the level of concentration? Caffeine is water soluble, and it is gotten by passing hot water through various grinds. Here is what could be influencing the concentrations of the buzz;

Saturation: the coffee grinds are supposed to be fully saturated so as to give all the caffeine in them.

Temperatures: water is the solvent in which caffeine dissolves. The water used should be close to boiling with a temperature of 95- 100°C to get the best results.

Time: most of the caffeine in the grind is extracted within the first of brewing, Espresso taking the shortest time, an average of 30 seconds.

Grind: the texture and size of grind determine the amount of time that will be taken to extract caffeine. The finer the grind, the faster caffeine is extracted. Finer grinds have a larger surface area for water to act on getting saturated quickly. This increases the amount of caffeine extracted.

The factors mentioned above determine the ease of caffeine extraction from coffee. The bigger the size of the grind, the longer the time taken. Espresso is made using highly pressurized hot water and finely ground beans, which gives higher amounts of caffeine in the shortest time.

 What Makes My Espresso Taste Bitter?

The taste and flavor of your Espresso are determined by your coffee grounds' size and the temperature of water used to make the brew. If you prepare your Espresso using coarse grounds, the water will not have enough surface area to act on and saturate the grounds because espresso id brewed in a very short time. This leads to under extraction of caffeine for your Espresso, resulting in a sour taste. Equally, if you use overly too fine grounds, water gets too much resistance, which slows down its flow and causes over-extraction of your Espresso. This produces a bitter brew.

Secondly, if you use water that is not near boiling, below 200°F, you get a sour espresso, and if your water is too hot, far beyond, 200°F, your espresso brew becomes bitter.

Which Espresso Machine Can I Buy For Domestic Use?

There are several espresso machines in the appliances stores suitable for home use. Your chosen machine should produce a great brew that deserves the name espresso. It is good to take time to evaluate and compare different brands of espresso machines and compare their features and specifications before making a purchase. Get a machine that will give you quality coffee brews to serve your family and guests and save you from terrible coffees sold as Espresso in some coffee shops.


Espresso shots contain around 1.5 to 2oz per serving, while ordinary coffee is, on average, 8 to 16oz per serving. With this, we can agree that Espresso is sort of stronger than black coffee in terms of ounces, but ordinary coffee is stronger than Espresso in terms of per serving.

While there is no actual measure for levels of concentrations between ordinary coffee and how much caffeine in a shot of Espresso, the latter is known to hit people faster than ordinary coffee. One can take up to 30 minutes sipping a cup of ordinary coffee while the maximum time to clear a single shot of Espresso is 3 minutes for the slowest drinker. This means that you get an average of 75 mg of caffeine instead of consuming 100 mg of caffeine 30 minutes later. In just 3 minutes, you will get that 'feel good' effect from Espresso, and that is the main theory behind the assumption that Espresso has more caffeine concentration than ordinary coffee.
