I just went an measured, about 18g of finely ground coffee fit into my 'double' espresso shot... However I could easily power through 5 of those a day.

I further fell from grace when I started packing as much as possible into a massive percolator for rocket fuel by the filled cup.

But you are right, 3 shots is probably not that much caffeine. It's somewhat hard to get good numbers on it.

Yes, and honestly you’re doing fine, because your 3 pulls of espresso is about the same as a Starbucks venti latte at 180-190mg. I think in Europe the caffeine content is even higher at something like 225mg for the same latte.

If you really, and I mean really want to have a go at the rocket fuel territory, you can do what many cafes in Istanbul now offer: Turkish coffee… at a regular coffee size. I think it takes about 150g of ground coffee per cup. That’s like pulling repeated shots of espresso till you fill a regular mug, except Turkish coffee is finer ground so has more caffeine than your average espresso per gram of coffee in.

Obviously, don’t try this if you have any medical conditions or sensitivity to caffeine, but this is what some Turks often drink on their days off.
