  1. No, it does not. The caffeine concentration is somewhat highier but not by much, while the overall amount of coffee is much lower. Espresso extracts the aromatics from coffee, but caffeine gets released slowly, so coffees in which the grounds are allowed to steep for longer are way richer of caffeine even if more diluted.

  2. No. People confuse the strong taste of coffee with the caffeine levels. Actually, it is the opposite. The more you roast a bean, the more caffeine escapes, the lower the caffeine content of the coffee.

    Original question: Does 1 espresso shot really have as much caffeine as a cup of coffee?

  3. No. An espresso actually has way less caffeine than a regular coffee does. The level of caffeine is based on how the bean is roasted….where its roasted and weather conditions. The lighter the roast the more caffeine it will contain.
    An espresso is in between a dark roast and a medium roast.
    The dark roast has 70 mg up to 115 mg of caffeine. Medium roast has 75 mg up to 120 mg and a light roast has 80 mg up to 130 mg.
    Decaf has up to 3 mg and a half caff has 50 percent less than a decaf. But teas and hot chocolate has up to 50 mg of caffeine.
    So an espresso has way less caffeine than a light roast coffee.
    That’s all an espresso is. It’s a 2oz. size of any coffee. There is nothing special about an espresso. Cause it’s just coffee brewed at a smaller cup size to slow the brewing process and to extract the flavor.

  4. One 2 oz double espresso shot has about 80 milligrams of caffeine. Whereas a 12 oz brewed coffee has about 120 milligrams. So actually there is more caffeine in an average cup of drip coffee than in espresso

  5. Yes, based on a regular amount of both. 80mg for a two oz shot vs 120mg for a 12oz pour (this will vary quite a bit depending on the grind, roast, and beans themselves).
    The water for espresso is forcibly pushed through very fine grounds for only about 20–25 seconds or so. While a good deal of extraction happens due to the fineness of the grounds, the water does not really steep for that long.
    With a drip coffee, the water steeps on the grounds for quite a bit longer – upwards of 3–4 minutes. And despite the grounds being quite a bit more coarse, that extra time allows for more caffeine extraction.
    If you want a heavily caffeinated drink, cold brew, which is extracted for hours, will give you the biggest hit.

  6. NO. A single shot of espresso (1 ounce, or 30ml) has about 60 milligrams of caffeine. An eight ounce (240 ml) cup of coffee has about 100 milligrams of caffeine. So the espresso is definitely stronger naturally, so it contains more caffeine PER OUNCE. But a 1 ounce espresso shot has just over 1/2 of the caffeine in an 8 ounce coffee.

  7. One 2 oz double espresso shot has about 80 milligrams of caffeine. Whereas a 12 oz brewed coffee has about 120 milligrams. So actually there is more caffeine in an average cup of drip coffee than espresso.


  8. According to the respected espresso coffee industry leader illy coffee

    The average cup of espresso has 78mg of caffeine

    According to the United Kingdom’s Food Standards Agency –

    The average cup of instant coffee has 75mg of caffeine
    The average cup of brewed, percolated and drip coffee has 100mg

    All the analysis I have read constantly identifies brewed, percolated and drip coffee as having more caffeine than espresso coffee (up to 125mg) and that’s comparing it with a 30ml espresso extraction which I think is 5ml more than ideal.
    Some research believes that it is the length of time that the hot water comes in contact with the ground coffee that produces the extra caffeine content. In espresso it is about 20-25 seconds while it is much longer in the brewed, percolated and drip coffee methods.
    Interestingly the better quality beans (Arabica) have about half the caffeine content of the cheaper ones (Robusta). So, I reckon that a 25ml shot of espresso made on 100% Arabica beans is a good option for reducing your caffeine intake while still enjoying that ‘elixir of the gods’.

  9. Since espresso is the only way to drink coffee correctly then its a null question.
    But if you mean if brown water served in USA sometimes referred to as coffee has more caffeine than an expresso then yes the other answers such as Peter’s one seem to indicate that this is correct.

  10. Is there more caffeine in espresso than in coffee?
    Surprisingly, a typical espresso contains less caffeine than a typical cup of coffee – by as much as half. This is due, it is thought, to the extremely fast extraction time of espresso under pressure compared to regular coffee prepared by other means…and also by the lower total volume.

  11. Q: Does 1 espresso shot really have as much caffeine as a cup of coffee?
    TL;DR: No. You need approx. one half US cup of drip coffee for the same amount of caffeine as is in one shot of espresso.
    Read below for more, since this is not always correct.

    That depends entirely on the size of each*! For most cases, no (but not mainly for the reason described in another answer**).
    Espresso has a higher concentration of caffeine than drip coffee.
    Drip coffee (assuming that’s what is meant by “a cup of coffee”) has around 270 – 675 mg/L caffeine, whereas espresso has ~ 1000 – 1700 mg/L caffeine (each depending on various factors) .
    So that means that (taking about average numbers from above, ~475 and 1350 mg/L, respectively), you drip coffee would need to be 2.8 times larger volume than your espresso in order to have the same total amount of caffeine.
    A standard espresso is 14 g (approx. 14 ml). But no one really makes “standard” espressos anymore, everyone does double, triple, or even higher dosing. So let’s say nowadays, an espresso you’d be likely to have served is maybe 42 ml, then you’d need ~120 mL of drip coffee.
    That’s one half US legal cup.
    If your drip coffee cup is larger than that, a cup of drip coffee will have more total caffeine.
    Again, in general, depending on a whole lot of variables.

    * If you use the same beans/roast for both, some beans have much more caffeine than others, and roasting levels of the same beans can also influence this. Also, what preparation do you call “a cup of coffee”? Drip coffee? Aeropress? Mocha?
    ** Espresso is ground much finer than coffee beans for drip coffee,

  12. Does 1 espresso shot really have as much caffeine as a cup of coffee?
    No, because espresso is a minimally extract cup which leaves some caffeine behind. Where as most other brews are maximally extracted removing most all caffeine from the grounds.

  13. I used to think espresso contained more caffeine, just like many. I think this has to do because we associate strong taste with more caffeine, however, as the others point out, this is not related. It also doesn’t work like alcohol, which has a correlation between the size of the drink and the amount of alcohol in it (roughly, the smaller the drink, the higher amount of alcohol in it).
    I think perception helps a lot too, because you expect to get a kick from an espresso, more than with a regular cup of coffee. And so, if you think it works, it mostly works (along with the actual amount of caffeine, of course). A ristretto tastes even stronger (it’s about half an espresso), yet contains even less caffeine.
    And then there’s cold brew coffee, which soaks for about 12–18 hours, after which you have a concentrate of coffee. You dilute this to your liking, but you probably still end up with more caffeine in your cup than any other type of coffee. How’s that for a kicker in the morning 🙂


  14. No it doesn’t. A cup of filter coffee typically has 2–3 times the amount of caffeine as a shot of espresso. This is because the extraction is longer and, therefore, you can extract more caffeine when brewing filter coffee.

  15. One shot of espresso (1 fluid ounce) contains around 75 mg of caffeine.
    One cup of filter/drip coffee (8 fluid ounces) contains around 165 mg of caffeine.
    The amount of caffeine varies slightly by roast level (by .06%) and bean variety (robusta beans have 1% more than arabica).

  16. An ounce of espresso as 63mg of caffeine
    Some companies consider one ounce a shot while some others do 3 ounces
    Standard coffee has 143mg per 8 fl. Oz. (It changes depending on brand)

  18. An espresso shot is usually LESS caffeine than a cup of coffee.
    Caffeine is water-soluble, so the longer it’s exposed to water, the more caffeine will be extracted. Brewed coffee is usually exposed to water from anywhere between 3-7 minutes, while a good espresso shot is only pulled for 25-35 seconds . It tastes stronger because it’s got more flavor packed into it (fine grinds, forceful pressure, smaller dose), but it’s not necessarily stronger.

  19. One shot equals one cup of regular coffee. And the coffee beans you use are the most relevant thing. Caffeine level is different in different kind of beans. Normally lighter roasted coffees has more caffeine than darker ones.

  20. It depends on a number of things like the pull of the expresso shot and how strong your coffee is but typically a shot of espresso is consided roughly equal to a cup of coffee in terms of amount of caffeine.

  21. How does a shot of espresso compare to a cup of coffee in terms of caffeine?

    Is Espresso Stronger Than Coffee?
    An espresso shot contains between 60 and 100 milligrams of caffeine, whereas a standard cup (12-ounce) of drip coffee can contain around 128 milligrams. Meaning, you’ll get more caffeine by drinking a cup of drip coffee. However, espresso has more caffeine per ounce than regular coffee.
    What Is The Difference Between Espresso And Regular Coffee?
    The grind’s fineness and the time it takes to brew the coffee differentiate espressos and regular coffee. Espresso is made of ground beans, usually ground directly by the espresso machine before brewing. Thus, the coffee has a thicker consistency, and you can make it much quicker than regular coffee.
    It can take up to 30 seconds to make an espresso depending on the machine, whereas drip coffee can take between three and five minutes.
    There’s quite some confusion as to how much caffeine in a coffee cup is compared to espresso. And sure, if you compare one shot of espresso to a full cup of coffee, the mug will have more caffeine.
    However, people don’t drink espresso in a mug, and you certainly don’t drink coffee in an espresso cup. A regular coffee cup can hold between 8 and 24 ounces, whereas a single espresso shot is usually around 1 ounce.
    What Makes An Espresso “Stronger”?
    The espresso flavor is quite different from drip coffee or even brewed coffee in a French press. Espresso has a bitter taste that some people find off-putting at the first sip. But is espresso stronger than coffee? The roast level will make the flavor…

  22. One of the coffee experts I follow is Peter Baskerville. His article cites research on caffeine content in coffee made using different methods. According to the article, coffee made using the drip filter method (commonly referred to as “regular coffee” in North America) has higher caffeine content compared with espresso.

  23. Another factor is the roasting. Dark roasting coffee loses a significant amount of caffeine. Most espressos are dark roasted.
    A light-roasted, Colombian robusto can have multiples of the caffeine content of a dark-roasted arabica from Ethiopia.
