Moxie is a brand of carbonated beverage that is among the first mass-produced soft drinks in the United States. It was created around 1876 by Augustin Thompson as a patent medicine called "Moxie Nerve Food" and was produced in Lowell, Massachusetts. The sweet soda is similar to root beer, with a bitter aftertaste. It is flavored with gentian root extract, an extremely bitter substance commonly used in herbal medicine.
Moxie was designated the official soft drink of Maine on May 10, 2005. It continues to be regionally popular today, particularly in New England states. It was previously produced by the Moxie Beverage Company of Bedford, New Hampshire until Moxie was purchased by The Coca-Cola Company in 2018.
The name has become the word "moxie" in American English, a noun meaning energy, determination, and spunk.
