Marthasville, Missouri
During the 1800s the area was settled by winemakers and workers from Germany. This part of the Missouri River Valley has become known as the Missouri Rhineland. The wines from this part of Missouri soon gained a worldwide reputation. At the 1851 Vienna World Exposition, Missouri wines took 8 of the 12 gold medals. French winemakers took notice and started importing the Norton/Cynthiana vines into France. But they were infected with a louse called Phylloxera. The louse had no effect on the Missouri rootstock, but in France it destroyed almost all of France's grapes. Two Missourians found a cure for the blight and the French vines were saved.
