Jimmy Buffett (C) and members of the Wounded Warrior Amputee Softball Team appear during the grand opening celebration for the Margaritaville Casino at Flamingo Las Vegas.

Last night, Margaritaville broke the World Record for the largest margarita ever made as verified by Guinness World Records. The event was part of the grand opening festivities for the new Margaritaville Casino at Flamingo Las Vegas.

Halfway through the ceremony celebrating the new World Record, Jimmy Buffett surprised fans by coming out and raising a glass of Lucky Rita with the Wounded Warrior Amputee Softball Team along with Flamingo’s Rick Mazer and Margaritaville’s Tamara Baldanza in front of more than 1,000 Parrotheads and onlookers.

“Much appreciation for these great wounded warriors, who I’ve worked with for a long time. Gentleman, thank you for coming out. We’re going to have a good time this weekend. Let the FIN begin,” Buffett said.

Lucky Rita is now on sale to the public allowing guests a taste of history and an opportunity to contribute to a great cause. For every gallon of Lucky Rita sold, Margaritaville will donate $5 to the Wounded Warrior Amputee Softball Team. More than a margarita, Lucky Rita is a concoction with a cause.

After six months of planning, the mixing of the colossal 8,500-gallon beverage, appropriately named “Lucky Rita,” began its first pour on Oct. 11. Lucky Rita took an estimated 300 work hours to mix the concoction. Lucky Rita kicks off Margaritaville Week with margaritas offered to the public until Oct.23.

Surpassing the previous record holder by 873 gallons, Lucky Rita’s Recipe Includes 2,125 gallons of Margaritaville Gold Tequila, 708 gallons of Margaritaville Triple Sec, 5,667 gallons Margarita mix and 22,267 limes. The recipe serves 181,333 12-ounce margaritas.
