How to make:
STIR all ingredients with ice & fine strain into chilled glass.
Orange zest twist
Go easy on the bitters and this is a complex and rewarding Martini-style drink.
In W.J. Tarling's (Bill Tarling) 1937 Café Royal Cocktail Book Coronation Edition, the creation of this drink is credited to one A. Mackintosh. Originally made with a brand of port called Clubland, hence this drink's name.
