How Many Ounces Are In A Shot Of Espresso

Espresso is the most popular coffee blend in the world. Almost every coffee shop you visit has it on the menu as the top coffee specialty. The coffee, an Italian creation, has a more significant caffeine concentration than the ordinary coffee.

You can choose to drink espresso on its own in a small cup, like a shot, or take it as a base for other espresso-based coffees. Some of the most popular coffees that use espresso as their base include latte, cappuccino, flat white, mocha, ristretto, etc. As popular as espresso is, it is also one of the most confusing beverages in the market.

Unlike its regular coffee counterpart, espresso is served in a small cup. The serving, referred to as a shot is confusing to many people, as they do not know how or understand why it a shot, how many ounces it is, how caffeine is in that small shot and many other things. In this article, we explain how many ounces are in a shot of espresso to enable you to understand your favourite drink more. .


Now to answer the question of the ounces in a shot of espresso, here goes;

A regular espresso serving is one ounce, which may sound like such a small amount that you may start to wonder how it makes espresso such a popular drink among so many people across the world. The small serving is that espresso goes through an intense process during brewing that reduces its volume immensely.

The brewing process that involves using hot water and pressure on the most finely ground coffee beans extracts more caffeine and flavor from the beans than it does liquid. The pressure exerted on the ground beans is 8 to 10 times higher than atmospheric pleasure, explaining the high caffeine content.

It is also the same reason that distinguishes espresso from regular coffee. Regular coffee does not have the same bold taste as that of espresso. An ounce of espresso contains 64 mg of caffeine, while a regular coffee contains ii grams in an ounce.

To enjoy the best out of espresso, you should also consider other measurements and variables besides the ounces. Some of the essential variables and measures include temperature, weight, volume, pressure, and time.


The temperature of the espresso brewing water plays a massive role in the outcome of the liquid. Temperature varies depending on the type of machine you are using, but the average should be between 195 and 205 degrees F.


The ground coffee beans' weight should be in the right measurements if you want the perfect espresso. A regular double-shot requires 17 to 18 grams of finely ground coffee while a single shot requires half. When you make an espresso, it is essential to use a scale or a double shot basket if you do not have a scale. You need to note that the double shot basket will not provide results that are as accurate a scale would.


High-end espresso machines come with gauges that read brewing pressure in bars. Pressure reading in bars may be new to many people, but here is a simple explanation. One bar represents sea-level atmospheric pressure, which equals 14.5 pounds per square inch.

The majority of the espresso machines have a minimum of nine bars, which is quite high. If you are using a machine without pressure bars, you can alternate that with extraction timing that helps you to determine whether you are in the right range of brewing pressure.

What is an Espresso Shot?

What is an Espresso Shot?

Not everyone that drinks espresso knows what an espresso shot. One of the reasons is that not all coffee shop attendants help people understand what a single shot or double shot means. Espresso servings are in either single or solo shots or double shots. A single-shot of espresso yields around 30 ml (1 ounce) of espresso, from 7 grams of fine ground coffee beans.

On the other hand, a double shot produces 60 ml (2 ounces) of espresso from 14 grams of finely ground coffee beans. In America, double shots are more popular, and if you ask for a solo shot, most probably, the baristas will serve a double and half it using a portafilter.

The single and double shot's flavor does not change because the only difference between the two is the volume. An ounce of espresso can contain caffeine levels of between 30 and 50 mg. A double shot, therefore, will have caffeine content of between 60 and 100 mg.

Ounces per Ristretto Shot


Ristretto means limited or restricted in Italian. A ristretto is a favorite with espresso connoisseurs that love gourmet espresso. It has the most aromatic qualities and finest tastes you could get from an espresso. A ristretto shot measures 15 ml that is half of an espresso shot. A double ristretto shot is twice the amount of a single shot, which is 30 ml.

The espresso drink uses the same amount of ground beans (7 grams) as the regular espresso. When you order a double ristretto shot, you have to wait for two pucks. The first line will pull 15 ml and the second one the same amount, which is different from regular double shot espresso that gives you the 2 ounces in one pull.

A ristretto shot is bolder and fuller than a regular espresso shot. A Ristretto has less bitterness than an espresso because, during the processing process,  coffee solids come out in the first few seconds. It also comes with a more pronounced flavor compared to that of a regular espresso.

The best coffees to use for pulling the most quality Ristretto are Ethiopian Yirgacheffe, Guatemala Antigua, and Sumatra Mandheling. All these coffees are Arabica, but you can add Robusta beans to the blend to enhance the caffeine and cream content.
