Wollersheim has been making garbage wine in Wisconsin since 1972, and using their own grapes since 1976, including garbage wines made entirely from bad grapes grown in Wisconsin. That Wisconsin wedding scourge, Prarie Fume uses New York grapes, however.

So uh, they been doin it a long time and uh, still not to my taste.

Also, their vineyard was originally built in the 1800s is the story, so grape cultivation was attempted back then too, I can imagine those wines were rough too.
