I Tested Caffeine Levels at Popular Coffee Shops (Unexpected Truth)

I tested caffeine levels at Starbucks, McDonalds, Blue Bottle, Dunkin Donuts, and Blank Street Coffee. Are the numbers actually accurate from what they posted online? Do different coffee shops diff wildly in their caffeine dosages in a double espresso? What should I test next?

A pharma grade caffeine control sample was needed. The quality assured sample would tell us how accurate the caffeine tester was.

Wearing a lab coat, I trust this dude with my life 🤝🏻

You should stir the coffee right before you take a sample so that the source is as homogenous as possible; that’s probably why you got varied results from doing back-to-back tests of the same cup.

Great video! I love seeing more testing going on! Wild to see the variance in what gets served as a double espresso though!

Also, when using this particular meter I found that you really need to mix the coffee right before pulling a sample (every time) in order to get a consistent reading. (Which would explain some of your variance).

My biggest take from this is to stop drinking energy drinks, and just start getting coffee from McDonalds before work

[HELLNAWW]

My unscientific opinion (but I have tried all of these numerous times): McDonalds Iced gets you absolutely lit, especially for the price. They have a coupon on the app for a cheap one frequently. I do find it more potent than all the other options here (even Starbucks). It's basically an energy drink with all the sugar, caffeine, and calories from the cream. McDonalds iced is the one that will make me freak out, Shakey, gut rot and cramps, and send my dopamine thru the roof, all signs of a good caffeine rush.

I wish this was done with regular coffee especially at dunkin.. I heard many stories of franchise owners being cheap and watering down their coffee

[marcberm]

Genius ad integration. Like you actually WANT to watch it. 👏💯

Love the commitment to the viewers, especially with the whole doc get up. Your parents will be proud (someday)

Would have been nice to test a decaf coffee

[melaniebluck]

I'm someone who's very sensitive to caffeine and it's so frustrating that a lot of companies do NOT provide any information on how much is in their products. I don't understand how you can sell a bottled beverage in a grocery store that literally contains a psychoactive compound in it, and not be required to list how much there is.

[georgeatte]

the wildest thing I learned from this video is that at some point they actually banned caffeine for athletes and was considered a PED and not so long ago as well !!

[ChaseTheSummit]

This was awesome! Surprisingly results, I’d be curious to see how this works on drinks like Red Bull or Prime Energy.

[milesdario]

My biggest take away from this video is realising how funny this mofo is 🤣

This channel is a gem. Keep killing the game Shervin!

I know this guy is a real scientist because he makes quantum leaps when counting. "One, Two, Three, Nine, Ten." Incredible!

Fun fact Caffeine has the opposite effect on people with ADHD, it can make you sleepy instead. Commonly referred to as caffeine naps.

[Dre_Lifts]

Loved the use of both chemisty and statistics to find your results!

[michaelcogliandro]

It would be cool if you took a few different roasts and brewed them each multiple ways, i.e. take a light roast and brew it as espresso, drip, french press, cold brew, then do the same with a medium roast then a dark roast. It would be interesting to see the caffeine differences.

[claycon]

If coffee is your primary caffeine source, you are always guessing at the amount bc there are SO many variables with coffee beans, roast methods, brew methods etc.

It’s best to know your own tolerance and base it on how you feel, while also trying to stay below 400mg per day on avg.
