The Sourest Candy in the World Challenge

Welcome to the ultimate test of your taste buds. If you've landed here, you've probably seen the reaction videos: red faces, watering eyes and people desperately trying not to spit out a sweet. That's the Barnetts Mega Sour effect. These are some of the sourest sweets you'll ever try, and taking them on has become a challenge in its own right.

What is the sourest candy challenge?

The #MegaSourChallenge is simple, in theory. Pop a Mega Sour in your mouth and keep it there until the sour coating wears off, which takes around 20 seconds. No spitting it out, and try not to pull a face. It sounds easy. It isn't.

The challenge has taken off on TikTok, Instagram and YouTube, with everyone from brave kids to unsuspecting parents filming their reactions. Most people underestimate just how sour these sweets are.

What makes Mega Sours so sour?

• An intense acid coating. Each sweet is coated in citric and malic acid, which hits your tongue the moment it goes in.
• A fizzy sherbet centre. Once you've survived the sour, the sherbet middle kicks in for round two.
• Traditional craftsmanship. Barnett Confectioners has made sweets in Nottingham since 1896, and Mega Sours are still made using traditional open copper pans.

Want a twist on the challenge?

Every Mega Sour flavour packs the same extreme sour coating, so the challenge is the same whichever you pick. For something different, try Zombie Bombz, our zombie-themed Mega Sour: seriously sour and seriously addictive.

Want to add heat? Zombie Bombz with a Hot Chilli Twist hits you with the sour first, then brings the heat. Sour and spicy in one sweet: this is the one to hand your bravest friend.
