I hate to be that guy, but, "source?" The espresso number "feels" a bit off, and some Internet searching agrees better with intuition:
According to USDA, 1oz of espresso is 63mg and 1C coffee is 92mg.
Just googling around, and both DDG and Google summary report 64mg/shot (with the obvious disclaimer about trusting AI summaries).
The chart is wrong on a couple things. Honestly, I'd argue this post should be removed or edited with the correct numbers.
Almost as much caffeine in hot chocolate as in expresso? This chart doesn't look plausible.
expresso
Ahhhhh!!!! Stop it. Please.
Also, it feels odd to compare them all by concentration. Red Bulls come in a specific size.
Also what roast of coffee? How long of a brew? How hot was the brewing water? What elevation did the beans grow? Way too many variables with coffee (and tea for that matter) to be this general
"affects" *
I once met an old journalist that ran a bed and breakfast in southern Ontario. Great guy who worked for the Toronto Star for several years in the 60s and 70s.
He said that work was a lot more hectic back then because everything was manual and you had constant deadlines with no conveniences. He said that his day started at about 5 or 6 and depending on how busy the day was, he'd be in bed by 2 or 3 or not at all to make a deadline.
He said he drank coffee but at one point drinking so much liquid was forcing them to go to the bathroom so much that he and a few others opted to start just eating the coffee beans instead. They got the caffeine kick without wanting to pee.
He suffered a massive heart attack in his 50s, slowed down after, quit eating coffee beans and retired in his 60s.
I assume they were all smoking nonstop as well, I’m surprised he even made it to 60
I remember him saying that after he saw a couple of his colleagues who were the same age, doing the same thing die either doing their work or shortly after ... he realized his time was up and he just retired before it killed him. Yes he said he did smoke like everyone, just not as heavily as most and he quit earlier than most.
He said he saw the writing on the wall and knew that if he continued, he would have died at his desk .... so he and his wife just packed it all in, sold everything they had in the city, moved to the country and opened a bed and breakfast instead.
His place was amazing tho ... they had a small library that was filled with all his old magazine, newspaper work, books, prints, documents, papers, everything ... and when you sat with him, he could sit for days telling you stories. This was all about 20 years ago and the old guy (he was in his 70s at the time) is probably gone now but what a character.
Yeah he definitely definitely sounds like a character, fucking off from your 9-5 to open a bed and breakfast is king shit
Drank three pots of strong coffee in 8 hours on the day I got my coffee machine during covid lockdowns.
Proceeded to code for 36 hours and have very distracting auditory hallucinations.
Good times.
Oof yeah. My mum has a good coffee machine, and when I moved out she offered it to me. I had to refuse because I knew that if it was just me in the house I would a) drink it to the point I would never sleep again, and b) it made me way more likely to visit her often if I know she has good coffee
pot of coffee every day
Weirdly, my sensitivity to caffeine has gone through the roof in my 40s. I just turned 48 and, if I drink just one cup of coffee after mid-day, I'm not going to get to sleep until about 3am.
Same, 2 coffees before 10am and then if I really neee one, a final coffee before midday. Anything beyond that time, forget sleeping
Work
Took caffeine pills, stayed up 4 days, saw strange colours, broke down and slept
Luckily made it home, the snow was looking really cosy
Sleep deprivation will scramble your brain.
After three days I got vivid hallucinations while driving. Traffic was coming straight for me on my side of a divided highway. Never again.
Longest I've stayed up is a 3 and bit days. I didn't hallucinate, because I wasn't drinking caffeine (you can stay surprisingly alert and mellow on just fruit), but I definitely had massive lapses in judgement when crossing the road
TIL: Cocoa contains a significant amount of caffeine...
Could be Theobromine?
Nope, contains both, checked Wikipedia:
The beans contain theobromine, and between 0.1% and 0.7% caffeine, whereas dry coffee beans are about 1.2% caffeine.
If I have too much coffee, I get irritating eye twitches and feel unpleasant.
Discovered that the caffeine in soda is the cause of bad munchies and not the same as coffee. Drink decaf soda and coffee now, lost weight, lol’d.
I tried decaf Coke Zero and I have to admit it makes me miserable. Can't work out if it's my head expecting the caffein high and not recieving it, or if it's something in the chemicals itself that acts as a depressant
Isn't caffeine in soda added in a relatively pure form in the end of the proces, unlike coffee/tea/cacao where it part of the 'source' of the end product? I don't think they have to substitute the caffeine for some decaf ingredient. If that's true, that would rule out your second guess.
Huh - that's actually good to hear. I thought they had to do the same creepy stuff they do to coffee to decaffeinate it, rather than just not adding it at all.
In that case I guess I've just got to train my brain to not immediately expect the caffeine high when drinking it
It's a chemical, so what's the difference? Anyway, yeah, people vastly underestimate how many calories they're drinking.
I thought green tea has more coffee than black?
I also thought that black tea had more caffeine that coffee. I guess I was wrong.
This is a random image on the web with no sources. Don't take it for fact. Checking your beliefs is good, checking them with other beliefs is circular logic and doesn't result in a more objective understanding of the world. Based off Kagi searchs black does on average have more caffeine, but also it varies and they're close.
Oh for sure, I did check a couple of sources before I posted. Thanks for looking out for us!
I have never in life had tea that was even close to the caffeine content in any given coffee.
Less than 400 mg a day is suggested for heart health.
My freshman year of college i drank one of the largest cans of red bull and a big coffee right before heading to a math class. I was tweaking scribbling absurd doodles in my notebook.
Did it help you math better, or were the doodles largely untethered to reality
The only thing I remember drawing was a stick figure ripping itself in half. For sure I was not at all paying attention to the professor.
tesselation of human parts
Threw 5/7ths of my life away
Back in the day, when I would hang out all day every day at a coffeehouse, I drank like three pots of coffee in two hours. I ended up standing up on a chair and flailing around, then completely crashing out and feeling like I was going to die.
Yep, sounds about right. One of the reasons I can't work on a laptop in a coffee shop (other than the maddening music on a loop you can't faze out) for long is just the creep of the caffeinated treadmill
Brewed coffee has more caffeine than an espresso?
Never thought of this. Thought they were relatively the same concentration.
Googling around and one oz (=1 shot as far as I can tell) of espresso seems more like 60mg caffeine.
I'm a little skeptical of the number in the graphic, especially since I don't see a source.
Espresso is smaller and these are absolute amounts, if they were percentages I'm sure the espresso would be higher.
They're probably using "cup" in the container sense, not the measurement sense. So it's shot of espresso vs mug of coffee.
The liquid you drink with filtered coffee has had much more time to steep in all the caffeine from the crushed beans compared to the espresso machine where the liquid travels though the crushed beans under high pressure. This graph might also consider size, but an americano is usually a double espresso with more water so i think they are refering to the brewing method and not the size.
filtered coffee has had much more time to steep in all the caffeine
True, but I think it's more complicated than that. Filtered coffee is typically a coarse grind, espresso is fine---and fine grind has a larger surface area to volume ratio, which helps with extraction.
I have also heard that caffeine leaches out fairly quickly, so it gets to be diminishing returns pretty quickly.
it's more complicated than that
Totally, i believe the bean and the burning process also matter in how much caffeine a cup of coffee has in the end. Also i believe espresso coffee is fattier wich influences the flavour and caffeine amount because a filter let's less particles true or something.
