150mg for a double shot of espresso, knock back three before lunch. Boom, I'm at 450mg and it's not really a whole load of volume to drink. It's easier than you think!

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

  IIRC the half-life of caffeine is approx 12 hours. So if you put caffeine in your body at 2:00 PM, half of it is still there at 2:00 AM.

    Different sources quote a half-life of 3-5 hours in healthy individuals who are not pregnant. https://sleepeducation.org/sleep-caffeine/ https://sleepeducation.org/sleep-caffeine/ 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/ 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.aspx 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.

  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.) :/

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.

    Sorry, probably a joke over head case, but on the https://www.breville.com/us/en/products/espresso/bes870.html https://www.breville.com/us/en/products/espresso/bes870.html you pick grind setting and amount yourself. There are others that do everything automatically, at a much higher price.

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.

  Back 10+ years ago when I had my machine 21g baskets were all the rage, and I think I remember whispers of larger.

    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.

      Operating margins, not gross margins right? Would you happen to know what's a "typical" wholesale cost (i.e. to the café) for third-wave beans?

        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.
