The Derby Daiquiri glass is from the Mai Kai in Ft. Lauderdale, FL. In 1959, the Mai Kai won a national cocktail competition with the Derby Daiquiri. This glass was created for the “$100,000 Drink,” with a golden stem in the shape of a jockey. For more on the recipe and story, see pages 154 & 160 of Beachbum Berry's Sippin' Safari. Morgantown also made a clear and a frosted stem version of this design, but it is the golden stem version that was used at the Mai Kai.
