What is "sundowner"?

Sundowner is a term used to describe a type of alcoholic drink that is typically consumed in the early evening, often while watching the sunset. The term has its roots in the British Empire, where it was used to describe a drink taken at sunset by colonial officials in Africa and India. The drink is usually a cocktail or mixed drink that is light and refreshing, such as a gin and tonic or a rum punch. Sundowners are often enjoyed in social settings, such as on a patio or at a beach bar, and are associated with relaxation and leisure.
