How Much Caffeine is in a Single Shot of Espresso?

Espresso is a specialized way of making coffee that originated in Italy, the method requires hot water to be exported under pressure through very fine coffee grains. Espresso can be made using various types of coffee beans and roast varieties. Espresso is usually more concentrated than coffee that is produced using different processing methods. This method of coffee production produces a thicker, more concentrated coffee. A shot of espresso usually serves as the base for many popular coffee beverages such as cappuccino, caffe latte, and Caffe macchiato. 

Espresso typically contains a higher percentage of caffeine per unit volume than other coffee types. However, contrary to popular belief, there is less caffeine in a shot of espresso compared to a regular size mug of coffee. The amount of caffeine found in a shot of espresso will vary depending on the origin of the beans used and the method used to roast the beans; these are factors that should be taken into consideration when comparing caffeine content.

According to nutritional data compiled by the Department of Agriculture, a single shot of espresso contains approximately 63mg of caffeine. A shot of regular coffee would usually contain approximately 12-16 mg of caffeine however, regular coffee is rarely consumed by the shot, it is often consumed in large coffee mugs, approximately 8 ounces of coffee per mug. This works out to be at least 95 to 128mg of coffee per mug. 

Espresso Origin 

An Italian inventor, Angelo Moriondo developed the concept for the espresso machine in the 1800s however, the machine failed to reach the commercial market. A few years later in 1906, Luigi Bezzera and Desiderio Pavoni developed another machine built off the back of Moriondo’s idea for a rapid-fire coffee machine. The idea of the machine was to create a single cup of coffee in seconds, “Caffe espresso.”

In the 1960’s Carlo Ernesto Valente further developed the espresso machine to produce a nine bar espresso machine which produced super fast shots of coffee. 

What is Caffeine? 

Caffeine is a naturally derived stimulant that is found in coffee, tea, cocoa, and various plants. It stimulates the brain and nervous system producing feelings of alertness, it provides the consumer with an extra boost of energy and some studies have shown that caffeine can boost concentration and focus. 

The first cup of coffee was produced in 2737 B.C. However, some historians report that coffee was discovered by an Ethiopian shepherd named Kaldi in the 9th Century. Whatever the case may be, caffeine has been around for many years, religious leaders and scholars have used caffeine as a tool to aid long prayer and study sessions, and it continues to be utilized effectively as a natural stimulant worldwide. 

How Does Caffeine Work in The Body? 

When you consume a caffeinated beverage or any food product that contains caffeine, the gut rapidly absorbs the caffeine and it quickly enters the bloodstream. It is then transported to the liver, where it breaks down and impacts different organs in the body. However, it primarily affects the brain. When you consume caffeine, you feel energetic and alert because it essentially inhibits the effects of adenosine, a neurotransmitter that causes tiredness. 

Often coffee drinkers experience the effects of espresso quickly because they drink it fast, regular cups of coffee are usually sipped slowly over time thus the caffeine hit is less intense. One cup of coffee can hit the bloodstream in about 15-20 minutes. Espresso shots usually take about 10 minutes to work, because they are concentrated and they are often consumed quickly. 

More Information About Espresso
