Moxie was developed by Augustin Thompson, a doctor and businessperson from Maine, in 1884, according to the Matthews Museum of Maine Heritage.
The drink was marketed for decades as having medicinal capabilities, such as fighting the "softening of the brain" and a "loss of manhood," according to the museum. Made from a root, it had a bitter aftertaste that's adored by some drinkers and hated by others.
Coca-Cola acquired the brand in 2018 for an undisclosed amount. Today, it's the state soft drink of Maine, according to the state government's website.
Each year, there's also the Moxie Festival, an event in Lisbon, Maine, for fans of the soda. This year's edition, scheduled for June, will feature fireworks, a 5K race, and a car show, according to its website.
