Don't know about homemade wines but I sure know about "Bologna Days" in the two communities
There is a bar called the Red Rooster Inn and you can go for "Bologna Days" once a week- you get a pitcher of beer for $5 (inflation could have changed that a bit), homemade pickles, home-churned butter, homemade white bread and a basket of ring bologna right out of the pot steamed with beer. Dennis, the owner, often brings out his concertina and plays a few tunes. The place is PACKED with locals and it is all an old-fashioned dream come true. The towns of Pierz and Genola are about one block apart. The meat market is in Pierz and the Red Rooster in Genola. Been there many, many times. Will go again any time I even get CLOSE to Minnesota.
I guarantee no ring bologna you can find will rival that of the quality the Pierz Meat Market produces.
