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).

Almost as much caffeine in hot chocolate as in expresso? This chart doesn't look plausible.

[–] ywuduyu@piefed.social 2 points 4 months ago

expresso

Ahhhhh!!!! Stop it. Please.

[–] gusgalarnyk@lemmy.world 11 points 4 months ago

The chart is wrong on a couple things. Honestly, I'd argue this post should be removed or edited with the correct numbers.

[–] CobblerScholar@lemmy.world 3 points 4 months ago

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

[–] JackbyDev@programming.dev 3 points 4 months ago

Also, it feels odd to compare them all by concentration. Red Bulls come in a specific size.

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

[–] ininewcrow@lemmy.ca 5 points 4 months ago (1 children)

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.

[–] Chronographs@lemmy.zip 4 points 4 months ago

Yeah he definitely definitely sounds like a character, fucking off from your 9-5 to open a bed and breakfast is king shit

Took caffeine pills, stayed up 4 days, saw strange colours, broke down and slept
Luckily made it home, the snow was looking really cosy

[–] dejected_warp_core@lemmy.world 4 points 4 months ago

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.

[–] tetris11@feddit.uk 2 points 4 months ago

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

[–] Multiplexer@discuss.tchncs.de 6 points 4 months ago (1 children)

TIL: Cocoa contains a significant amount of caffeine...

[–] blimthepixie@lemmy.dbzer0.com 1 points 4 months ago (1 children)
[–] Multiplexer@discuss.tchncs.de 2 points 4 months ago

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.

[–] homesweethomeMrL@lemmy.world 4 points 4 months ago (2 children)

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.

[–] tetris11@feddit.uk 3 points 4 months ago (1 children)

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

[–] huppakee@piefed.social 2 points 4 months ago (1 children)

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.

[–] tetris11@feddit.uk 2 points 4 months ago

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

[–] shalafi@lemmy.world 1 points 4 months ago

It's a chemical, so what's the difference? Anyway, yeah, people vastly underestimate how many calories they're drinking.

[–] apfelwoiSchoppen@lemmy.world 4 points 4 months ago

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.

[–] tetris11@feddit.uk 1 points 4 months ago (1 children)

Did it help you math better, or were the doodles largely untethered to reality

[–] JillyB@beehaw.org 2 points 4 months ago (1 children)

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.

I thought green tea has more coffee than black?

[–] Doomsider@lemmy.world 1 points 4 months ago (2 children)

I also thought that black tea had more caffeine that coffee. I guess I was wrong.

[–] gusgalarnyk@lemmy.world 5 points 4 months ago (1 children)

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.

[–] Doomsider@lemmy.world 2 points 4 months ago* (last edited 4 months ago)

Oh for sure, I did check a couple of sources before I posted. Thanks for looking out for us!

[–] shalafi@lemmy.world 2 points 4 months ago

I have never in life had tea that was even close to the caffeine content in any given coffee.

[–] YeahIgotskills2@lemmy.world 3 points 4 months ago* (last edited 4 months ago) (1 children)

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.

[–] tetris11@feddit.uk 1 points 4 months ago

Same, 2 coffees before 10am and then if I really neee one, a final coffee before midday. Anything beyond that time, forget sleeping

[–] Triumph@fedia.io 2 points 4 months ago (1 children)

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.

Brewed coffee as opposed to dry beans? Assuming you mean black it is espresso with water. Green tea is about 30-40mg what is this :D

[–] pricklypearbear@lemmy.world 1 points 4 months ago* (last edited 4 months ago) (4 children)

Brewed coffee has more caffeine than an espresso?

Never thought of this. Thought they were relatively the same concentration.

[–] qjkxbmwvz@startrek.website 6 points 4 months ago

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.

[–] NickwithaC@lemmy.world 4 points 4 months ago

Espresso is smaller and these are absolute amounts, if they were percentages I'm sure the espresso would be higher.

[–] IrateAnteater@sh.itjust.works 4 points 4 months ago

They're probably using "cup" in the container sense, not the measurement sense. So it's shot of espresso vs mug of coffee.

[–] huppakee@piefed.social 2 points 4 months ago (1 children)

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.

[–] qjkxbmwvz@startrek.website 1 points 4 months ago (1 children)

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.

[–] huppakee@piefed.social 2 points 4 months ago* (last edited 4 months ago)

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.
