This is how I learned to make the famous drink of Larchmont Yacht Club on Long Island Sound. It is named for the great drinking/racing family of Commodore, Bizzy, and Jimmy Montesano. You can look for their name on sailing trophies everywhere. When at Larchmont a Monte-Sano is standard operating gear for all activites. Best when made by the pitcher for all the crew, paid for by the skipper.
