Underdog Wine & Spirits took its first step into the rum category with the introduction of Flipflop Silver and Spiced rums. Originating in the Caribbean, Flipflop Silver Rum is four times distilled, resulting in an 80-proof rum with a clean flavor and crisp finish, the company says. Spices and natural flavors are added to Flipflop Silver rum to create the 70-proof Flipflop Spiced rum that features finishing flavors of cinnamon and vanilla, it adds. Flipflop Silver and Spiced rums are available in 750-ml. and 1.75-liter bottles for approximately $13.99 and $22.99, respectively. Proceeds from the sale of Flipflop rums will support Soles4Souls, a not-for-profit organization that facilitates the donation of shoes for those in need in communities around the world.
