Number of gallons that comprise the largest cocktail ever made. Nick Nicora of Ovations Food Services in Sacramento, California, created his giant “Calarita” Margarita ten years ago at the California State Fair. The Guinness Book of World Records recorded Nick’s concoction as the largest cocktail ever made in a giant cocktail shaker. In case you’d like to replicate it, you’ll need 2,100 gallons of tequila, 4 gallons of Cointreau, 2,800 gallons of Margarita mix, 75 40-pound bags of ice, 5,190 gallons of water, and 50 gallons of lime juice. The only thing we don’t know is how many people you’ll need to drink it.
