Backstory

The Glasgow Mule doesn't have a single credited inventor but emerged during the craft cocktail revival of the early 21st century. As bartenders began experimenting with classic formulas, swapping vodka for other spirits in the Moscow Mule became a popular trend. Naming this variation after Glasgow, Scotland's largest city, was a natural fit, creating a direct link to the drink's new spiritual home.
Origin
The cocktail is a modern invention, likely originating in the United States or the United Kingdom in the 2000s. It is a direct descendant of the Moscow Mule, which was created in the 1940s.
