6 pack of Adirondack Beverages Root Beer soda. My own personal opinion, for an "off-brand" this root beer is pretty good!
From their web site:
"Since over 86% of any soft drink is water, it's our most important ingredient. The Adirondack® Aquifer Well is our one source of water for soft drinks and seltzers and is certified by The New York State Department of Health. In fact, Adirondack is one of the few soft drinks you can buy that is not made with municipal water."
