The Boston Tea Party helped popularize coffee in America. The hefty tea tax imposed on the colonies in 1773 resulted in America switching from tea to coffee. In the lead up to the Revolutionary War, it became patriotic to sip java instead of tea. The Civil War made the drink more pervasive. Coffee helped energize tired troops, and drinking it became an expression of freedom.
