National Henry C. Ramos Day is celebrated on October 27 to honor Henry C. Ramos, known for creating the iconic Ramos Gin Fizz cocktail. This day was established by William Grant & Sons to recognize Ramos's contributions to the cocktail world. The Ramos Gin Fizz, a mixture of lemon juice, sugar, and carbonated water, is noted for its unique preparation method that involves vigorous shaking for about 12 to 15 minutes. There is some debate over whether Henry or his brother, Henrico C. Ramos, was the original creator of the drink, but Henry is typically credited with its formulation. The cocktail gained popularity in New Orleans, where Ramos and his brother owned the Imperial Cabinet saloon. Celebrations may include enjoying Ramos Gin Fizz cocktails, reflecting on its history, and recognizing its significance in the realm of mixology.
