Maine - Moxie
Moxie was originally invented in Massachusetts. However, no state loves it more than Maine. It even named Moxie as the official state drink!
Maryland - Shasta
Did you know Shasta's first soft drink was a ginger ale? The company produced it back in 1931, despite being named after a spring in California. It's also based in Maryland, so none of this really makes any sense, but it still tastes great.
