Bertie Bott's Every Flavor Beans are one of the most popular sweets in the wizarding world. They are the same as Muggle jelly beans, except the range encompasses every flavour imaginable. There is also no way of telling for sure what flavour any given bean is without tasting it, although you can try and guess by the color. The inventor of Bertie Bott's Every Flavour Beans was Bertie Bott, who created them in mid-20th century by mistake. He was planning on making tasty sweets from food, but accidentally made one taste like a dirty sock. He immediately recognised the sales potential of "a risk with every mouthful!"There are ordinary flavours like chocolate, peppermint, and marmalade, but also less fanciable ones like spinach, liver, and tripe. There are also flavours that are not actual foods, like grass, farm dirt, vomit, earwax, paper and bogeys. In 1992, while Harry is in the hospital wing, he offered one to Professor Dumbledore. Dumbledore told him that he had been unfortunate enough to have come across a vomit flavour one in the past and since that occasion he had not cared for them. In spite of this, he decided to give them another chance and carefully selected a golden brown-coloured one that he assumed would be toffee-flavoured, but alas it was an earwax-flavoured bean. They are a popular treat at Hogwarts School of Witchcraft and Wizardry and can be bought off the lunch trolley on the Hogwarts Express and in Honeydukes and are usually sent as a gift to someone ill in the hospital wing. They come in bags or small, striped boxes.
