What got the farmers in western Pennsylvania so upset?

in 1794 when farmers of western pennsylvania protested against the whiskey tax. this was an "excessive" tax-an internal tax passed a few years before to raise additional funds for the national government. They were mad about this because usually they make grain into whiskey. the whiskey rebellion can be called the first large scale protest demonstration after the federal government was organized under the constitution. The whiskey rebellion was significant because washington showed that the federal government had the strength to enforce its law; his reaction attracted supporters to the federalist cause.
