That's the way to do it. No sugars or anything, just that great taste.
I saved a huge amount of money going from pods to a manual Breville Barista, which whilst making coffee shop quality brew is also far better for the environment. Price of purchase was recovered in 6 months, and all savings from there.
Heads up, this depends on what you mean by double shot of espresso. One ‘payload’ of espresso as regularly consumed is usually 15-18g of ground coffee and has about 75mg of caffeine. Confusingly, traditionally and especially in Italy this is called a ‘double’ espresso. Because of that reason it’s better to talk about caffeine in terms of grams in.
Unless you are pulling two shots of espresso into the same cup (which will likely overflow your average espresso cup) your caffeine intake per shot of espresso is 60 to 75mg. I don’t know of any portafilter basket that would let you get to 150mg in one pull, that would be a quadruple espresso.
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.
Yes, that used to be the case I think. The espresso world backed off of that in the last few years. Nowadays the average dose is trending lower. Possibly, half the reason is that a larger dose is more inefficient (i.e. it drops your extraction rate) and the other half is that coffee costs money and for coffee shops that operate at 5-10% margins, 14g doses (standard Italian double espresso) vs 21g (the ‘third wave’ dose up till a few years ago) does make a meaningful difference in whether the store is under water or not. I think it’s settling around 16-18g.
Yes. James Hoffmann on YouTube talks more about the margins of coffee business if you'd like to learn more, that's where my knowledge comes from for the most part.
Holy shit, I would be bouncing off the walls if I drank that much coffee. I can't even handle one in the morning and one in the afternoon or I will be awake until 4 in the morning
People metabolize caffeine at wildly different rates depending on their genes. One cup every other day in the morning is my limit until I see significant effects on deep sleep (as measured by a Dreem 2.) :/
Different sources quote a half-life of 3-5 hours in healthy individuals who are not pregnant.

Caffeine begins to affect your body very quickly. It reaches a peak level in your blood within 30 to 60 minutes. It has a half-life of 3 to 5 hours.
https://www.ncbi.nlm.nih.gov/books/NBK223808/
The mean half-life of caffeine in plasma of healthy individuals is about 5 hours. However, caffeine's elimination half-life may range between 1.5 and 9.5 hours,
https://www.news-medical.net/health/Caffeine-Pharmacology.as...
The half-life of caffeine (time taken for the body to eliminate one-half of the caffeine) varies widely between people, depending on factors such as age, body weight, pregnancy status, medication intake and liver health. In healthy adults, the half-life is approximately 5 to 6 hours. Heavy cigarette smoking can decrease the half-life of caffeine by up to a half and in pregnancy, the half-life may be increased by as much as 15 hours. [...] The stimulatory effects of caffeine may begin as early as 15 minutes after ingesting the drug and last as long as six hours.
