That seems like an absurd amount of coffee to drink in one day, no?
- senectus1 5y agoyeah during my worse abuses of coffee i was pushing my limits in 5-6 and regretting it purely from a "sick feeling". I don't have any issues sleeping no matter how much coffee I drink. but "stomaching it" is a different matter entirely.

- Xunjin 5y agoMy IBS looks at this and thinks "No shit, Sherlock! Actually is gonna be tons of shit after this". Stepping aside myself trying to make a Brazilian's joke in English, a single cup of coffee (around 80mg-120mg) really give me cramps and sometimes diarrhea.
- ip26 5y agoIt is, but maybe it helped surface a small signal that was always there but harder to identify in people who drank less, for example.
- JimTheMan 5y ago150mg 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!
- TapWaterBandit 5y agoHoly 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
- TedDoesntTalk 5y agoIIRC 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.
- skmurphy 5y agoDifferent 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.
- dota_fanatic 5y agoPeople 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.) :/
- sundvor 5y agoThat'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.
- FPGAhacker 5y agoWhat is manual about a bee like barista?
- sundvor 5y agoSorry, 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.
- rolleiflex 5y agoHeads 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.
- andreareina 5y agoBack 10+ years ago when I had my machine 21g baskets were all the rage, and I think I remember whispers of larger.
- rolleiflex 5y agoYes, 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.
- andreareina 5y agoOperating 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?
- rolleiflex 5y agoYes. 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.
- vsef 5y agoI always start the day splitting a 12 cup pot with my husband, frequently we make more later in the morning. It's really nothing if you are habituated to it and not especially caffeine sensitive. I know many other similarly heavy coffee drinkers.
- ilaksh 5y agoYou drink six cups of coffee in something like a three hour period? Seems like some kind of addiction. What do you gain from that?
- vsef 5y agoIt tastes good, especially with breakfast food, wakes me up a bit, and is hydrating. I experience no negatives, and nothing in particular happens to me if I skip it either. It seems implausible to frame as an addiction unless you start from the preconception that caffeine must be a vice. And according to this article, and others, I apparently gain various health benefits from my preferred beverage to boot :)
- HKH2 5y agoIf it's spaced out well, it should be fine. It might make one feel a bit hot/irritable though. Often caffeine tablets are sold as 200mg, so it's just two of those. (One bottle of tablets I have says don't exceed 5 pills in 24 hours - 1 gram!)
- sundvor 5y agoBe careful with caffeine supplements such as pills and (especially) powders. Overdosing is far too easy and can be a substantial health risk, even deadly - https://www.health.com/nutrition/caffeine-powder-overdose https://www.health.com/nutrition/caffeine-powder-overdose
- nostromo 5y agoEight ounce cups are quite small. For reference, at Starbucks it’s called a “short.” I know lots of people in my office will drink two 16 oz cups a day, which is equivalent.
- TedDoesntTalk 5y ago> two 16 oz cups a day Put another way, That’s two pints of beer. That’s a lot of coffee to me.
- paulryanrogers 5y agoIt is, especially for folks with health conditions or smaller body types. Cherry picking studies (mostly funded by producers) means never having to admit your vices are a problem.
- jayd16 5y agoNot really. My very boring drip coffee machine doesn't even have a notch below 4 cups.
- biggc 5y agoI could be wrong, but I think the “cups” on a coffee maker are 4oz each
- TedDoesntTalk 5y agoYou’re right. 4-5 “cups” of 8 ounces is 2 - 2.5 pint beer glasses (they are 16 oz each).
- CTDOCodebases 5y agoI hope not. I worked in the coffee industry and consumed 10-20 shots of espresso a day. Sometimes more.
- 3np 5y agoSeems average for a coffee-drinking office worker. One for breakfast, one for lunch and one between each major meal (assuming 100mg per cup which would be normal for a middle-roast brew coffee). But as others have mentioned, it’s hard to control for other factors. I imagine 300+ mg of caffeine is also associated with a less sedentary lifestyle, for example.
