Bertie Bott's Every Flavour Beans

"You want to be careful with those. When they say every flavour, they mean every flavour - you know you get all the ordinary ones like chocolate and peppermint and marmalade, but then you can get spinach and liver and tripe. George reckons he had a bogey-flavoured one once."

- Ron Weasley to Harry Potter

Bertie Bott's Every Flavour Beans are one of the most popular sweets in the wizarding world. They are the same as Muggle jelly beans, except they have every flavour, and there is no way of telling if a certain bean is a certain flavour. You can guess from the colour of the bean. 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 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 truly foods, like vomit, earwax, and bogeys.

In 1992, while Harry is in the hospital wing, Albus Dumbledore tells him that he was unfortunate enough to come across a vomit flavour one. Since then he has not liked them. He tries again and eats an earwax-flavoured bean.

It is a popular treat at Hogwarts School of Witchcraft and Wizardry and can be bought off the lunch trolley on the Hogwarts Express, and is usually sent as a gift to someone ill in the Hospital wing. They come in bags or small, striped boxes. A total of 169 flavours are known.

Known flavours
"Ah! Bertie Bott's Every Flavour Beans! I was most unfortunate in my youth to come across a vomit-flavoured one. And since then, I'm afraid I've lost my liking for them. But I think I could be safe with a nice toffee... Hum! Alas! Earwax."

- Albus Dumbledore

Behind the scenes

 * In Harry Potter and the Philosopher's Stone, Albus Dumbledore is heard saying that he had the misfortune of coming across a vomit-flavoured bean in his youth. As he was at least 44 years old when the inventor was born, this seems unlikely. However given his old age it is possible Dumbledore perceived himself as still being in his youth at that stage of his life.
 * In the real world, Jelly Belly released jelly beans with selected flavours from the series. There are currently 25 flavours available. The review website Candy Addict rated these candies as #4 of the "10 grossest candies." The Bertie Bott's candies may have been inspired by Jelly Belly, which produces jellybeans in unexpected flavors like jalapeno and encourages consumers to eat different-flavoured jellybeans in combination to create different flavours.
