The Most Sour Candy in the World


The Sourest Candy On Earth

If you’re like me, there’s nothing better than sour candy. For some reason, the combination of sweet and tart just makes my mouth water and makes me want to keep chasing that flavor.

Well, pucker up, folks and get ready for some of the sourest candy you’ve ever encountered. Some of the candy you’ll see below is so sour that you won't be able to talk with it in your mouth. Some are so sour that you'll want to spit it out as soon as you can.

Below, you can find a countdown of the sourest candies in the world, which have been rated on a scale of 1 to 5 according to their sourness, tastiness, and how long the flavor lasts. A “1” is as bland as your grandmother’s oatmeal, while a “5” will burn your taste buds off. Buckle up and enjoy!


#8 - SweetTarts

  • Sourness: 1
  • Tastiness: 5
  • Long-Lasting: 2

Sweet Tarts are a classic and so can’t be left off the list. But, for the real sour fans among us, Sweet Tarts are child’s play: a tiny dollop of sour on a fruit candy. Though safe enough to feed to your Great Aunt Edna, Sweet Tarts are still delicious: the little hint of sour just makes the sweet taste that much stronger. Get SweetTarts for the sweet, not the sour.


#7 - Sour Nerds

  • Sourness: 1.5
  • Tastiness 4
  • Long-Lasting: 1

Real proof that there's strength in numbers. No one eats just one Nerd, if such a thing is even possible. While individually, Nerds aren’t that sour, if you get a big mouthful of these little devils you’ll still go to go into sour overdrive. These are worse, in our opinion, than the sour Gobstoppers, also made by Wonka. At least there's only one big Gobstopper, and if it's too much you can spit it out. Nerds are a lot harder to get rid of -- and we've tried.


#6 - Sour Punch Straws

  • Sourness: 2
  • Tastiness 5
  • Long-Lasting: 3

These sweets are not as powerfully sour as some of the others on this list. They're really more like candy, but sour punch straws show up on "most sour candy" lists online. It's surprising but true -- sour punch straws are a sweet that lightweights can handle, but sour candy enthusiasts can appreciate. One thing I like about the Sour Punch Straws is that there’s not just a single outer layer of sour coating. Instead, it’s sour the whole way through so you get a nice even dose of sourness as you eat each one. Pick up some Sour Punch Straws and share them with your sweeter friends and family.


#5 - Sour Flush

  • Sourness: 3.5
  • Tastiness 4.5
  • Long-Lasting: 2

Maybe not quite as brutally sour as the other candies on this list, but it still rates a mention for bad taste alone. This gross little item requires you to dip a plunger into a toilet bowl of yummy sweet and sourness and then lick it off. And repeat. How much do you REALLY like candy? The sourness for this candy varies by flavor: for instance, the blue raspberry flavor is sourer than the grape.


#4 - Cry Baby Tears: Extra Sour Candy

  • Sourness: 4
  • Tastiness 5
  • Long-Lasting: 2

These are so sour they come right our and call them tears. Well, crybaby? Are you gonna cry? Probably not, especially after you've had Toxic Waste -- these just aren't quite as powerful as those "stunt candies." But, all things considered, these are a good choice for your sour enjoyment -- sour enough to know it matters, but not enough to take the enamel off you teeth (see Toxic waste above). Get Cry Baby Tears and see for yourself.


#3 - Altoids Apple Sours and Lemon

  • Sourness: 4
  • Tastiness 3
  • Long-Lasting: 5

Packing that traditional Altoids punch in the mouth, these apple sours are the kind of sour candies that they hardly make anymore. Not exactly the freak-out that Nuclear Waste represents -- more like an old-fashioned smackdown from the big glass canister on the counter. Apple Sour Altoids will make your teeth itch, but they won't send you running for cover.

Altoids Apple Sours are one thing; Altoids Lemon Sours are quite another. The sweet/sour charm of Altoids Apples are meant to be more like candy while the lemons are meant to be... well, an experience. Although not as brutal as the kick-in-the-teeth power delivered by Warheads or Toxic Waste, Altoids Sour Lemons are a surprisingly strong sour candy. It's easy to picture an unsuspecting person popping a few of these little guys into their mouth, expecting a mildly sour experience, and winding up with tears in their eyes. Don't say you haven't been warned!


#2 - Atomic Warheads

  • Sourness: 5
  • Tastiness: 5
  • Long-Lasting: 4

Plenty of people swear by these bad boys as the most extreme example of sour candy out there -- even to the point of having contests and timing their endurance: whoever spits it out first loses (or wins, depending on how you look at it). Loaded with a double-handful of citric acid, the sour substance supreme, Warheads also have a touch of sugar just to keep you entertained while your eyes water. Not fun in the least, but with sour candy, enjoyment is hardly the point, right?

As if it weren't enough abuse to actually chew Warheads, there's another delivery system that seems designed by a mad scientist, or at least someone with a twisted sense of humor. Now you can spray your Warheads straight down your gullet. That's right, Spray Warheads. Just when you thought American culture couldn't rise any higher.


#1 - Toxic Waste

  • Sourness: 5+
  • Tastiness: 1
  • Long-Lasting: 2.5

This stuff is pretty nasty no matter how you look at it. Definitely the sourest of the bunch. It’s accurately named, at least: to call it anything else would be false advertising. Toxic Waste candy is so loaded with face-shrinking, mouth-puckering, saliva-inducing citric acid that you are advised – seriously – to brush your teeth or at least rinse your mouth afterwards so that you don’t hurt your teeth. That's right, Toxic Waste is so sour it can dissolve your tooth enamel. Fun!

Toxic Waste may be the sourest candy ever. However, if you can make it past the first 30-45 seconds or so, the sour coating will eventually dissolve, and it’ll actually start to taste like something you want to eat. But that first 45 seconds or so is pretty awful.

Toxic Waste Challenge: Are You Ready?

If you're wondering how your ability to withstand the sour onslaught of Toxic Waste, they very helpfully provide you with a rating system to test your strength. If you take a look at the back of the case, you can find the Toxic Waste Challenge: a double-dog dare to try to keep the toxic waste in as long as you can. Here's how the rankings break down:

15 Seconds: Total Wuss!

30 Seconds: Cry Baby!

45 Seconds: Toxie Wannabe!

60 Seconds: FULL TOXIE HERO!

If you're angry at one of your friends, you can play it with them: make it a competition to see who can hold it in their mouths the longest. Just be careful when you lay this stuff on a friend, because really who wants a friend with an inside-out head? How can you go to Arby's with a dude with an inside-out head? This is a world-sized question, people.


Bonus Entry: What Could be Better than Toxic Waste? Nuclear Sludge!

Because, let's face it, when the radioactive mess starts leaking out of the reactor and pouring down the street where you live, you're gonna want it to taste like sour cherry. Am I right? Pour some of this acidic stuff into your mouth and hang on. It's got one of the highest ratios of ultra-tart additives of any candy you can buy. It gives Toxic Waste a run for its money as the most sour candy in the world.
