A Hawthorne strainer is a bar tool used to strain cocktails when pouring them into a glass. It features a flat, circular design with a spring coil around the edge, which helps to catch ice and other solid ingredients while allowing the liquid to flow through. This ensures a smooth drink without any unwanted particles. Typically used in conjunction with a cocktail shaker, the Hawthorne strainer is essential for bartenders. It is named after the American writer Nathaniel Hawthorne, reflecting its historical significance in cocktail culture. This tool is popular in both professional bars and home mixology.
