About Mighty Swell

Unpredictable at times, but nothing to worry about. The bold flavors of Mighty Swell Spiked Seltzer are the result of using only natural ingredients. They are from Austin, where being real is the only option and weirdness is expected. They like to keep things real, weird, and really weird. In each flavor, Mighty Swell uses only 2. 5% juice and a clean ingredient deck. This means that there is no sodium benzonate, artificial sweeteners, red dye #3, high-fructose corn syrup, or artificial flavors. Ever. Simply check each package's ingredient deck! They use white grape juice, which includes 3 grams of sugar, for a crisp, balanced taste in every spiked seltzer.
