NEW ORLEANS (WGNO) - Seventy-five years ago three people sitting at a Hollywood bar created the Moscow Mule.

The great grandson of the mug's creator, J. J. Resnick, is in New Orleans this week paying homage to his great grandmother, who is sometimes forgotten in the legend of the Moscow Mule.

Resnick believes this copper mug is the key ingredient to the timeless drink.
