Question: The Watershed Distillery offers what spirit that has been distilled since the 18th century?

Bourbon has been distilled since the 18th century.  The name is derived from the French Bourbon dynasty, although it is unclear precisely what inspired the whiskey's name (contenders include Bourbon County in Kentucky and Bourbon Street in New Orleans).  The use of the term "bourbon" for the whiskey has been traced to the 1820s, and the term began to be used consistently in Kentucky in the 1870s.  While bourbon may be made anywhere in the United States, it is strongly associated with the American South, and with Kentucky in particular.  As of 2014, the distillers' wholesale market revenue for bourbon sold within the U.S. is about $2.7 billion, and bourbon makes up about two-thirds of the $1.6 billion of U.S. exports of distilled spirits.
