How many shots of espresso would pose a genuine health threat?

Let's say someone dared you to drink a certain number of espresso shots all at once.

Assuming no unusual health factors/allergies, etc etc...

At what point would it go from:

1) Kinda funny --> not feeling so hot shortly after
2) Not feeling so hot --> an actual health issue

5 shots? 8 shots? 12?

And what would that health issue entail other than some diarrhea on exit? Or would your system simply self-regulate without any possible side effects from an entire gallon of espresso? Can you OD on caffeine?

When your heart is thrashing around in your chest like the Alien trying to get out (first Alien movie), you've had enough.

It's possible to OD on caffeine, and it's possible to die from a caffeine OD. Not sure of what dose that would take but IIRC it's fairly massive (something like 75 cups of coffee).

It may not take as much as you think...if you are on the wrong kind of medication. Caffeine can really f' with meds.

a cup of espresso (1oz) has less caffeine than a cup (12oz) of regular coffee. people think there is a lot because there is a little more per ounce than regular coffee.

i had 9 shots one year at christmas in a 1.5 hours and was fine.


Coffee, tall (12 oz.) Starbucks - 325
Espresso (1 oz.) Starbucks - 35

10 shots of espresso would be 350mg caf

12 shots is only about 20% more than one coffee.

I routinely have 2 Rockstars and/or some coffees.

I guess I should be glad I'm not dead yet?

Define the caffeine content of one shot of espresso (I know it vaires), then once you get enough to = 10 grams, you have a good chance at having a serious problem.


The LD_50 of caffeine (that is the lethal dosage reported to kill 50% of the population) is estimated at 10 grams for oral administration. As it is usually the case, lethal dosage varies from individual to individual according to weight. Ingestion of 150mg/kg of caffeine seems to be the LD_50 for all people. That is, people weighting 50 kilos have an LD_50 of approx. 7.5 grams, people weighting 80 kilos have an LD_50 of about 12 grams.

I think it would depend on a number of things, including your weight and whether you are on any medications that would adversely react to a lot of caffeine in your system.

I don't like espresso enough to try.

Don't know what your politics are but you're financially supporting that asshole talk show host Michael Savage every time you buy a Rock Star drink.

I'm sorry, but there's no way your numbers are correct. I drink 2, 3 cups of coffee sometimes. There is no possible way I am drinking the equivalent of more than 30 espresso shots.

Try again? Or is there something else at play here?

One serving of espresso has less than a serving of coffee, and the serving is obviously far smaller. But there is no way the caffeine content of a serving of espresso is less than 10% of a cup of coffee. Sorry. That's just not correct.

So back on topic... let's say someone offers me 1000 bucks to drink 12 oz. of espresso. Do I suck it up and go for it or kindly let them know that they are attempting murder?

What if it's 24oz? 48?

I know 5 or 6 is no problem, and I drink as much as 8 in a day but not all at once.

Is the espresso armor-piercing?

Is it true that espresso has less caffeine than regular coffee?

What happens when you overdose?

I used to work with a guy who claims he used to drink 32 cups of coffee a day. Of course the whole weight theory might apply because he was probably 275 lbs at least.

32 cups of coffee a day would probably give you headache, nausea and probably those heart beating thing, but nothing else serious as far as I know of.

32 cups of coffee in one sitting, however... now that's something different.
