I was alerted that there is a documentary (sort of) on making wine in Wisconsin which features HAV vineyard in Fredonia, WI, Steve - owner of Parallel 44 and Amaya Atucha, Fruit Extension Specialist at UW-Madison.
The program is on the Newsy TV which is 3.6 if you have a digital antenna or it can be view at https://www.newsy.com/stories/in-real-life-winesconsin/. it's about 20 minutes long and I thought well done for a quick intro to wine production in WI.
