Barnetts Mega Sour Watermelon is juicy watermelon sour candy that starts seriously sour and finishes sweet. Each hard sour candy ball has an extreme sour coating that lasts around 20 seconds, then gives way to a sweet watermelon centre with a fizzy sherbet finish. One of the fruitiest flavours in the range once the sour wears off.
Known on TikTok as the world's sourest candy, Mega Sours have become the go-to sweets for the #MegaSourChallenge: keep one in until the sour wears off, without pulling a face.
