How much caffeine in a double shot of espresso? The amount of caffeine contained within this compact yet powerful serving can vary based on several factors, including the type of coffee bean, the grind size, and the brewing method.

What is a Double Espresso?
A double espresso, sometimes called a doppio, is simply two shots of espresso extracted from the espresso machine.
| Term | Definition |
|---|---|
| Espresso | A style of coffee that is made by forcing very hot water under high pressure through finely ground coffee beans. |
| Single espresso | One shot of espresso, generally around 1 ounce. |
| Double espresso | Two shots of espresso extracted together, generally around 2 ounces. |
The main difference between a single and a double espresso comes down to yield – a double espresso extract yields twice as much coffee liquid because twice as much water is pushed through the coffee grounds.
How Much Caffeine In A Double Shot Of Espresso?
It’s tricky to give an exact caffeine amount for a double espresso. The caffeine content can range quite a bit based on a few key factors:
- Coffee varietal – The type of coffee plant impacts caffeine levels. Arabica beans are lower in caffeine than Robusta.
- Roast level – Darker roasts actually have slightly less caffeine than lighter roasts.
- Coffee amount – Using more ground coffee will increase caffeine. A double shot uses around 14 grams.
- Brewing method – Espresso concentrates the caffeine whereas drip coffee dilutes it.
With all those variables, a double espresso shot likely provides between 70-120mg of caffeine on average. Of course, the actual amount can be higher or lower based on the factors above.
Health Impacts of Double Espresso Caffeine
Consuming a double espresso gives you a concentrated jolt of caffeine, which can provide both benefits and drawbacks depending on the person and dosage.
Positive Effects
- Increased energy and alertness
- Elevated mood and focus
- Enhanced motor coordination and reaction time
Negative Effects
- Jitters, anxiety or nervousness
- Insomnia or sleep disruption
- Upset stomach, nausea, and diarrhea
Caffeine affects people differently based on individual sensitivity. It’s important to pay attention to how your body responds to assess the right dosage for you.
More About the Double Espresso
Now let’s dig a little deeper into the double espresso itself beyond just the caffeine content.
- To pull a proper double shot, you need around 14 grams of ground coffee. Too little coffee and the shot will be weak, too much and it will be overextracted.
- Choosing the right coffee beans impacts flavor. Medium roasts are ideal for espresso to highlight sweetness and acidity. Single origin beans from Central/South America work well.
- Perfecting your espresso comes down to grind size, dose, tamping, and timing. Fine grinding is key for espresso brewing to extract properly. Aim for an extraction time of around 25-30 seconds.
- Espresso stands out for its concentration. Adding water to dilute it makes an Americano. Adding steamed milk provides volume for lattes and cappuccinos.
- From a nutritional standpoint, espresso is very low calorie and contains negligible fat or carbs. Any calories come from the added dairy and sweeteners.
Alternatives for a Caffeine Boost
Double espresso provides a potent caffeine kick but certainly isn’t the only option if you need an energy boost. Here are some alternatives:
- Brew a strong drip coffee using more grounds per water volume.
- Opt for espresso drinks with steamed milk like lattes and cappuccinos which provide texture and sweetness alongside caffeine.
- Consider a cold brew coffee which can be very smooth yet concentrated.
Double Espresso vs. Other Espresso Drinks
There are a few other types of espresso drinks that are worth comparing to the double espresso:
- A lungo is an espresso shot pulled longer, generally twice as much liquid. This dilutes the caffeine slightly but provides more volume.
- A ristretto uses half as much water for a more concentrated, less bitter short shot. Caffeine is similar or slightly lower.
- Overall, a double espresso strikes a balance – more caffeine than a single, but more intensity in flavor than a lungo.
How to Make Double Espresso at Home?
Want to start making double espresso yourself? Here are some tips:
- Make sure your equipment is hot – allow your espresso machine to warm up for at least 15 minutes before pulling shots.
- Use a fine grind for espresso, much finer than for drip coffee. A quality burr grinder helps get the right texture.
- Add the ground coffee to the portafilter, then distribute evenly and tamp firmly to compress. This helps optimize extraction.
- Pay attention during extraction – stop when the espresso starts blonding and the crema fades. This usually takes around 25-30 seconds.
- Try different coffee amounts and grind settings. Vary tamping pressure. Experiment to get your perfect double!
- For milk foam, steam until microfoam forms. Then pour gently through the crema for latte art!
Making delicious double espresso at home does require some equipment and practice. But the reward is having your perfect customized espresso shots whenever you want your caffeine fix!
Conclusion: how much caffeine in a double shot of espresso
The caffeine content in double espresso can vary quite a bit based on the coffee beans and preparation method used. While it’s difficult to provide an exact milligram amount, a good estimate is 70-120mg per double shot on average. Consuming this concentrated jolt of caffeine provides both energizing benefits as well as potential side effects depending on the individual. Beyond just caffeine, double espresso showcases the intense, bold flavors of espresso. With the right beans and some practice, you can make cafe-quality doubles at home to start your day right.
