The Most Sour Candy in the World

Updated on July 2, 2016

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.

#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.

This candy is TOO HOT for Most People

#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.

#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).

#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!

Sourness: 4Tastiness 3Long-Lasting: 5

#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! Don't believe me? Check out the video below of people trying tasting it for the first time.

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 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.

TOXIC WASTE Hazardously Sour Candy, 1.7-Ounce Plastic Drums (Pack of 12)
TOXIC WASTE Hazardously Sour Candy, 1.7-Ounce Plastic Drums (Pack of 12)

This stuff is surprisingly hard to find in some areas, maybe because some areas know what's good for them and what's you, know, TOXIC. And waste.


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.

      Once my family went to Newfoundland and brought back a bag of no brand sour balls. They were about two inches in diameter, and probably about as hard as a dum-dum pop, but holy F U C K were they the most sour, most delicious candies I've ever tasted. Imagine the sourness you get on the outside of a warhead, but the flavor of the candy itself is actually good and it's sour all the way through. They were much easier to eat crushed up, and I could only eat a couple before my tongue and gums felt raw. I really wish I knew what they were called, because they topped all of the candies on this list by a million.

      +1 for Barnett mega sours i ate 10 over the course of a hour, my tongue had cracks which eventually bled and couldn't taste much at all the next day and i dont regret it at all. My missus looked at me after about 6 and my eyes were watering and cheeks were swollen yet i still kept going and trying to act normal in a woman's underwear shop haha

      warheads are sour for about 5 seconds and after that they are sweet. The toxic waste are ok but they dont last long either. there are smog balls bu toxic waste and they are quite sour and they are sour all the way through. some tend to be a little sweet but 80% are very sour. sour nerds should not even be on this list. or the sour punch straws those are not sour.

      Toxic waste is good and warheads are pretty similar but Barnetts mega sour balls out of the UK are well above both, other than warheads and toxic waste (and obviously the mega sours) nothing on the list is sour, and nothing lasts forever, wish the sour would last for minutes not 30 seconds of less, not a fan once it goes away

      I had just recently bought some candy at the market. The guy selling them had a whole range of sours I could choose from, I was going for the toxic waste then he said that this other packet of candies were the most sour. I doubted him but gave it a shot as I 'had his word for it'. A few minutes later I shoved one of them into my mouth and it was torture! Normally I'd take anything like toxic waste like it was nothing but this one was demonic! My tongue then stopped tasting for the next hour or so. Unfortunately, the candies are only branded with the place I bought them from s you won't be able to get them from anywhere else (I think)... So beat that Toxic Waste!

      I love toxic waste sweets. The double layered red tub ones are the best. To all saying they're not sour... grow up, you know they are. If you want to go for the ultimate in sour mix half a teaspoon sugar with half a teaspoon of citric acid and a third of a teaspoon malic acid and see how long you can keep that in your mouth!

      Ok so i have been eating this sour powder for ever and i recomend the true sour lovers do this too. I buy a slurpee from the 7-11. Then i buy koolaid unsweatened packets. I pour the koolaid powder on the top of the slurpee and scoop it off with a small sour key. I use about 4 packets and the fourth one is just mixed into the slurpee and at the end what ever slurpee is left is now a great sour slurpee of your choice flavor of koolaid.

      I am still on the quest to find genuinely sour candy. Almost all of the ones I've ever tried--and all of the ones on here--that are marketed as "sour" are really what I'd call "fake sours"....meaning, they're completely sweet except for a thin sour layer or tart powder on the outside. I like the taste of most of them, but they're not sour. Don't they have any that are really made for hardcore sour-lovers?
