Cas Oh

A veteran of the London bar scene, Cas Oh has helmed an array of iconic bar venues and is known for his obsessive approach to research and training. His first book, CO Specs, showcases the recipes & histories of some of the world's best known cocktails.

Title trivia: C & O are the author’s initials. ’Specs’ is bartender parlance; a shortening of ‘specification’ (aka a recipe). This project began as Cas’ work on his own personal recipes, and later morphed into a book — hence ‘the CO Specs’.
