What kind of whiskey was involved in the Whiskey Rebellion?

Whiskey distilled from surplus corn was at the heart of this 1794 rebellion by western Pennsylvania farmers.

The farmers refused to pay a federal excise tax on whiskey, which was easier to store and transport than corn and was even used as currency.

President George Washington stopped the rebellion with a force of 13,000 militiamen.

The tax itself was repealed once Thomas Jefferson took office as president in 1801.
