Kombucha Town, Bellingham, Wash., said it launched Live Seltzer, a hybrid between two of the fastest-growing and most popular categories in the beverage industry over the last 20 years: functional beverages and seltzers.

According to the company, Live Seltzer is a proprietary blend of Kombucha Town’s organic and non-GMO raw kombucha cultures, fresh-pressed “hero” ingredients and carbonated water from the North Cascade mountains.
