A: One 2 oz double espresso shot has about 80 milligrams of caffeine. Whereas a 12 oz brewed coffee has about 120 milligrams. So there is more caffeine in an average cup of drip coffee than in espresso.
An Australian study investigating five popular types of coffee brewing methods has found that espresso contains the highest concentration of caffeine.
You'll be happy to know regular pre ground coffee can be used for an espresso machine, provided it has the right fine grind. Many coffee drinkers also prefer to use dark roasted coffee due to its stronger flavor.
Espresso is brewed by forcing hot water through finely ground coffee under extremely high pressure. This results in a highly concentrated shot of coffee with a caramelly sweetness and a distinctive crema (layer of foam) on top. While it looks simple, pulling a quality shot requires considerable skill and practice.
Espresso has the most caffeine per volume; however, the volume of an espresso shot is really small.

What's interesting here is the fact that they found that espresso actually had the lowest caffeine content at 100 mg per 2 ounces. Next was coffee brewed in the French press with 107.5 mg per 7 ounces. Drip-brewed coffee came in last with 145 mg of caffeine per 7-ounce cup.
Another factor that affects the caffeine content is the size of the grind. Finely ground coffee beans produce a more caffeinated coffee because they have a larger surface area overall and a higher extraction. Finally, the hotter the water used to brew, the more extraction and thus more caffeine your coffee will have.
Espresso and coffee are not different things. Espresso is a type of coffee. More specifically, it's a method of brewing coffee that uses high water pressure and finely ground beans to make a small, concentrated shot (the term also refers to the shot itself).
Many people think espresso and coffee are two distinct beverages, but they're actually just different brewing methods. Both types of drinks have similar benefits, although light- to medium-roasted coffee has a slight edge over espresso for supporting heart health, cognitive health, metabolic health, and more.
You can use Turkish coffee for an espresso machine, but it won't taste good. Turkish coffee grounds are actually finer than espresso coffee grounds, resulting in a flavor that won't quite taste right when put into your portafilter.
But how much is an actual shot of espresso? A single shot of espresso requires approximately seven to nine grams of ground coffee and produces one fluid ounce. A double shot of espresso, called a doppio, requires 14 to 18 grams of coffee and produces two fluid ounces.
How much caffeine is there in a cup of Turkish coffee? Turkish coffee is highly caffeinated and contains around 25 mg of caffeine per ounce.
Espresso typically has 63 mg of caffeine in 1 ounce (the amount in one shot), according to Department of Agriculture nutrition data. Regular coffee, by contrast, has 12 to 16 mg of caffeine in every ounce, on average. That means that ounce for ounce, espresso has more caffeine.
To Make Strong Coffee, Adjust Your Coffee to Water Ratio
To make a stronger brew, just increase the amount of grounds used without altering the quantity of water you use. This will alter the ratio and produce a stronger cup.
For example: an 8oz cup of brewed coffee (which is the most common method in the US and Europe) yields about 70 - 140 mg of caffeine. Espresso (which is made by forcing a small amount of hot water, or steam, through finely ground coffee beans) has more caffeine per volume than regular coffee.
It also is a much healthier choice than the normal types of coffee that many people drink throughout the day. Instead of loading up with sugars and creams, espresso can be enjoyed as is, leaving out those extra calories and fats. You can get that energy boost without sacrificing your health.

But espresso is known for being easier on the stomach for a couple of reasons. First, the combination of high pressure and short extraction time produces a different balance of chemical compounds than the same coffee would in a drip or pour over brew.
Turkish coffee requires an extremely fine grind (1) – finer than espresso – and should feel like powder. This extra-fine grind is crucial to the whole Turkish brew method, and what gives it its distinctive body.
The more finely ground the beans, the more caffeine is released into the water. So it's safe to say that when it comes to caffeination, a finer grind does result in stronger coffee, while a coarser grind will always brew a weaker cup.
There's an average of 63mg of caffeine in a single shot of espresso (1 fl oz / 30 ml) when using 7g of coffee. It's important to note that there's a lot of variation in coffee dosage used across the industry, and this will affect the caffeine content in your cup of coffee.
Generally it's agreed that per drop, espresso wins on caffeine. A typical shot of espresso is about an ounce and has 30-50mg of caffeine. A cup of Turkish is about two ounces and usually has around 65mg of caffeine. Bump that espresso to a double and it's pushing 100mg.
Arabica beans: In contrast with the Robusta coffee beans, Arabica beans are known for their mild taste, so they are a better option for people who don't like bitter coffee. On top of that, Arabica beans have a sweeter taste, contrasting with the bitterness of coffee.
Bottom line: When it comes to caffeine consumption, coffee or tea (without any added sugars or cream) are among the healthier options.
