This article explores the emergence of cocktail culture in interwar Singapore. Mixed alcoholic drinks were consumed by British men in Singapore from at least the 1910s, including the famous “Singapore Sling.” However, it was not until the 1920s that cocktails became the drink of choice for elite men and women from Singapore’s Chinese, British, and Eurasian communities. The consumption of American popular culture and exchange with American colonists in the Philippines helped the cocktail to become a symbol of tropical modernity. At the same time, the possibilities of home entertaining were transformed by the increasing availability of American-made domestic refrigerators in Singapore from the mid-1920s. Multiethnic elites, accustomed to frequenting bars and cafés to enjoy cocktails, began to host their own cocktail parties with the help of their Chinese servants. The interwar cocktail party offered the wealthy a means to display conspicuous consumption and cosmopolitan modernity. They did so in a way that unsettled but did not overturn colonial hierarchies based on gender, race, and class.
