This cocktail has 26 ingredients - one for each letter of the alphabet

In this version of a 26-ingredient cocktail (maybe the only version), every spirit, bitter, and digestif must start with a different letter of the alphabet.

Twenty-six ingredients, 26 letters. It's called the A-Z cocktail. Get it? It was thought up by Bompas & Parr, a London culinary design studio that has also brought breathable alcohol and collagen gin into existence.

"It would be all too easy to randomly combine a minibar's worth of ingredients and make something undrinkable. The challenge here was to create something beyond novelty for its own sake and end up with a balanced drink," says Harry Parr, co-founder of Bompas & Parr and the cocktail's creator.

The A-Z cocktail, modelled after a traditional rum punch recipe, tastes similar to liquified cough drops, herbal and honeyed. Mostly, it's syrupy sweet. But over lots of rocks, it's like drinking root beer after school... but with 45 percent ABV.
