We are proud to bring you three flavors of what we know are the cleanest, most brightly flavored, balanced and completely un-junked seltzers on the market. How do we know this? After conducting over a year of market research, and tasting hundreds of seltzers, we developed a process of brewing and filtration that separates the taste of Gray Duck Spirited Seltzer from all others. Simply put, our seltzer is the most purely natural tasting drink of its kind…period! 5% ABV.
