The original. Hand crafted. Flavored vodka with a southern accent. Firefly is the original sweet tea flavored vodka, first created at the Firefly Distillery on Wadmalaw Island, South Carolina. It is handcrafted vodka, infused with the only tea grown in America, less than 5 miles from the distillery. The taste is sweet, the kick is sweeter. What does Long Island know about tea anyway? Caramel color added. 35% alc by vol (70 proof).
