About the author

CO Specs is the award winning debut title penned by drinks industry veteran Cas Oh.
The book is the product of 20 years behind the bar, mixing drinks, managing teams, and training staff in such notable venues as The Groucho Club and the Hospital Club. Most recently Oh was running the bars at the iconic 'Ivy Club' in London's West End, where he held the tiller for a decade before leaving to finalise the manuscript for CO Specs. Known for his obsessive approach to research and training, this book is the 'one stop shop' he always wished he'd had.
