How Much Caffeine is in One Shot of Espresso

Espresso, that rich, concentrated shot of coffee, is a beloved morning ritual for many. But behind its potent flavor lies a question that lingers for some: How Much Caffeine is in One Shot of Espresso?

Key Takeaways:

  • A single shot of espresso typically contains 63mg of caffeine, but can range from 50mg to 100mg depending on various factors.
  • Double shots double the caffeine content.
  • Milk-based espresso drinks have a lower caffeine concentration per ounce compared to a straight shot, but the total caffeine content can increase with larger sizes.

Caffeine in Coffee vs Espresso

While a typical cup of coffee has around 12 to 16 mg of caffeine per ounce. A standard espresso has per one-ounce shot around 63mg of caffeine, according to the USDA.

However, this number can vary depending on:

  • Bean Power: Robusta beans have nearly double the caffeine content of Arabica beans. The blend used can impact the final caffeine punch.
  • Roast Profile: Darker roasts tend to have slightly less caffeine due to the roasting process.
  • The Brewer’s Touch: Extraction methods and grind size can influence the final amount of caffeine in your espresso shot.

So, while 63mg caffeine in one shot of espresso is a good baseline, the actual caffeine content of your espresso shot could range from 50mg to 100mg.

Size Matters – Single vs. Double Shots

If you’re a double-shot kind of espresso drinker, you’re essentially doubling your caffeine intake. A double shot, also known as a doppio, can pack around 150mg of caffeine.

Different Espresso-Based Brews

Many popular coffee drinks are espresso-based. Here’s a quick caffeine guide for these beverages:

  • Cappuccino, Latte, Macchiato: A small or “short” size might have around 75mg, while larger sizes like “grande” or “venti” can reach 150mg. Keep in mind, the larger the drink, the more milk is added, diluting the espresso’s caffeine concentration.
  • Lungo: This “long pull” espresso shot uses more water, resulting in a larger drink with a slightly lower caffeine concentration per ounce compared to a regular shot.

The Effects of (Too Much) Caffeine

Espresso’s caffeine kick can be a lifesaver, but exceeding your limits can lead to some unwanted side effects. Here’s what to watch out for:

  • Jitters and Anxiety: That potent buzz can morph into shakiness, nervousness, and even anxiety, especially for caffeine-sensitive individuals.
  • Sleepless Nights: Caffeine disrupts sleep patterns. Consuming espresso later in the day can make it harder to fall asleep and stay asleep.

  • Headache Hell: Caffeine withdrawal can cause headaches, making that daily espresso seem necessary, but ironically, perpetuating the cycle.
  • Digestive Discomfort: Espresso can increase stomach acid production, leading to heartburn, indigestion, and upset stomach.
  • Rapid Heart Rate: Caffeine can raise your heart rate, which can be especially concerning for people with heart conditions.
  • Dehydration: While espresso itself contains some water, caffeine has a diuretic effect, increasing urination and potentially leading to dehydration.
