Sour flavour is one of the core notes that the human tongue can detect, and many of our favourite foods and drinks wouldn't be the same without it. What would lemonade, vinegar, sweet and sour sauce -- and many of the world's most popular candies -- be without their generous helpings of sour flavour? They'd be boring! Likewise, a sour vape juice is one that uses a sour note to add some much-needed excitement to tart flavour profiles such as candy, lemonade, citrus fruits, sorbets and more. The best sour e-liquid typically uses malic acid, the same stuff that candy makers use to craft their sour creations. Although no e-liquid has quite that level of sourness -- too much sour flavour covers an e-liquid's other notes -- you'll find that many of the e-liquids on this page pack quite a punch.
