Comparing coffee, soda, energy drinks, energy shots and more.
I have a bit of a reputation of being a Diet Coke zealot. I’ve picked my poison and whatever chemicals are in Diet Coke are my poison of choice. I assume it’s better for me than meth or huffing glue. Because, obviously, those are the only three options.
I got into a debate over the weekend about just how much caffeine I consume daily through only having soda. I argued that Diet Coke (and all sodas) are relatively low in caffeine compared to other options. Others were skeptical. I didn’t have the facts handy. Now I do.
I did a lot of research into caffeine content to put together this list. Yes, it’s a very personal subject; if this were any cop procedural the captain would’ve tried to pull me off the case and put me on desk duty rather than make this list because I’m too close to it. But like any good TV detective, I’d rather beg forgiveness than ask permission.
So here are 11 enlightening facts about caffeine. I originally called it “11 Eye-Opening Facts About Caffeine” but even I have to draw the line somewhere. I’m already coming out as a Diet Coke zealot here… can’t simultaneously come out as a pun zealot too.
1 | A tall Starbucks has about 7.6 times the caffeine of a can of Coke and 5.8 times the caffeine of a can of Diet Coke
The broad lesson of this list is: Drinking a cup of Starbucks coffee is just about the easiest way to flood yourself with crazy amounts of caffeine.
A tall (12 ounce), regular coffee at Starbucks contains an average of 260 milligrams of caffeine. (A grande has 340; a Venti has 420.)
A 12-ounce can of Coke — or, to put it in Starbucks terms, a tall Coke — has 34 mg of caffeine. That’s about 7.6 times less than the same size Starbucks. A 12-ounce Diet Coke has 45 mg of caffeine; that’s about 5.8 times less than the same size Starbucks.
So… you’d have to drink eight cans of Coke or six cans of Diet Coke to equal one cup of Starbucks. Put another way, you’d have to drink a full two-liter of Diet Coke to consume the same amount of caffeine as one 12-ounce cup of regular Starbucks coffee.
Non-Starbucks coffee usually isn’t quite as caffeine-laden as Starbucks, but it still outpaces soda. The average 12-ounce cup of brewed/drip/instant coffee has between 100 to 260 mg of caffeine. Even on the lowest end, that’s still the caffeine equivalent of three cans of Coke or two cans of Diet Coke.
2 | A 12-ounce can of Red Bull has less caffeine than an average cup of coffee
One of the 12-ounce cans of Red Bull — those are the bigger ones, not the lean Virginia Slims ones — contains about 114 mg of caffeine. That’s less than the average cup of coffee (and less than half of a cup from Starbucks). But Red Bull also has a ton of other
placebos mystery energy herbs that give you imaginary wings and enable you to compete in oddly random soap box derbies. The only extras you get from drinking Starbucks are Lily Allen CDs and competitions featuring 15 people with MacBook Pros vying for two power outlets.
3 | Decaf coffee has caffeine
If you’re trying to do a zero caffeine thing, decaf coffee isn’t perfect. The average cup of decaf has around 5 mg of caffeine — not a lot, but not zero. A study in 2003 found Starbucks decaf has around 9 to 12 mg of caffeine. Decaf from Dunkin’ Donuts, Krispy Kreme and McDonald’s had similar amounts.
Caffeine-free sodas are much more reliable as decaf options; they actually have zero mg of caffeine. So does water. But I promise this isn’t going to turn into one of those rants about why you should drink water that have become so ubiquitous and overbearing we now instinctively tune them out. Instead, let’s talk about the opposite of water, tiny fruit-flavored caffeine shots made of a ton of chemicals…
4 | 5-Hour Energy packs an extraordinary amount of caffeine into a tiny bottle
A two-ounce bottle of 5-Hour Energy has 138 mg of caffeine. That’s a Skrillexian 69 mg of caffeine per ounce. To compare, Coke has 2.8 mg per ounce, Red Bull has 9.5 mg per ounce, Starbucks coffee has 22 mg per ounce and espresso has 51 mg per ounce.
So if you drank 12 ounces of 5-Hour Energy, you’d get 828 mg of caffeine. That’s arguably in the lethal zone, and definitely in the “guy who no one likes at a rave” zone.
5 | Two tablets of Excedrin have the same amount of caffeine as 5-Hour Energy
Beat your headache by signal jamming it with caffeine. Each tablet of Excedrin has 65 mg of caffeine, so when you pop the standard dose of two tablets you’ve taken down the equivalent of a 5-Hour Energy. And if you wash your Excedrin down with 5-Hour Energy, you’re probably going to forget your headache altogether (while you rearrange furniture or film a Micro Machines commercial).
6 | One scoop of coffee ice cream has more caffeine than a can of soda
My mom is particularly partial to coffee ice cream. Which, it turns out, contains anywhere from 45 to 75 mg of caffeine per 8-ounce serving. That’s more than a can of soda and comes close to the same amount as a smaller can of Red Bull. Did my mom know this whole time? Is she secretly a caffeine addict? Does my family have a chance at starring in the lamest episode of Intervention ever? Could I muster tears while saying, “She would eat coffee ice cream over all the other flavors and we never thought anything of it. And oy, the headaches she’d get when she couldn’t have a cup of coffee on Yom Kippur morning”?
7 | You have to eat a lot of chocolate before the caffeine affects you
There’s caffeine in chocolate, but it’s not much (especially in heavily-processed milk chocolate). Hershey’s Kisses have about 1 mg of caffeine in each one; Reese’s Peanut Butter Cups have 4 mg in each; Milky Way has the highest of the popular candies at 14 mg in a bar. You’d have to go Augustus Gloop before you could take in enough chocolate to get a caffeine rush.
8 | The old Jolt Cola had less caffeine than any of today’s energy drinks
When I was in elementary school and middle school, all the other guys buzzed about Jolt Cola. It wasn’t in many stores but it was the stuff of legends. And all because of its caffeine content — twice the caffeine of Coke!
Here’s the problem with messing with nostalgia. It’s never quite as good when you venture out of your memories and actually look at it through older eyes. I watch He-Man and can’t believe how much I loved the bargain basement animation. I look at Hulk Hogan’s WrestleMania main events and have to make sure I’m not watching in slow motion. And investigating Jolt Cola, sadly, reaped the same letdown.
Jolt Cola only had 72 mg in a 12-ounce can. That’s double what Coke has… but less than any of today’s energy drinks. Today’s kids don’t need to hunt down mysterious, quasi-forbidden Jolt Cola when they can buy those giant cans of Rockstar.
9 | A can of Four Loko was more dangerous because of the alcohol than the caffeine
Four Loko original recipe was banned not only because it’s fun to distract people from real issues, but because of its caffeine-alcohol combo.
The widespread belief it that the caffeine was the problem. But looking at the numbers, that wasn’t its unique problem. It was the alcohol.
A can of original Four Loko was 23.5 ounces and had 156 mg of caffeine — that’s a lot of aggregate caffeine but less per ounce than any coffee or energy drink. The issue came from the 12 percent alcohol-by-volume; that means each can contained 2.82 ounces of alcohol. That’s a lot.
Whiskey is generally 40 percent ABV, meaning a standard 1.5-ounce shot contains 0.6 ounces of alcohol. So for an Irish coffee to achieve the same effect as Four Loko on both caffeine and alcohol content, you’d need an eight ounce cup of coffee containing four to five shots.
But, of course, there are other drinks that can be just as potent as Four Loko. If you can find a stronger whiskey, you can pull it off in a large Irish coffee. Adding Bacardi 151 to Pepsi Max could get you in the ballpark. Or, of course, you could play Edbrewed Fortyhands (where, obviously, you tape a 40 to one hand and a cup of coffee to the other).
10 | Tea is generally less caffeinated than coffee, more caffeinated than soda
Based on a survey with the sample size of one (my girlfriend), there’s a misconception that tea is comparable to coffee in terms of caffeine. It is not. Twelve ounces of brewed, chai or iced tea average 72 mg of caffeine — less than all but the weakest coffee and more than all but the Joltiest sodas.
11 | No-Doz and Vivarin have more caffeine per pill than virtually any other caffeine source
Each No-Doz and Vivarin pill contains 200 mg of caffeine. A number that astronomical is both so exciting and so scary.
