Thanks for the add on. I'm not new to wine making, been at it for about 10 years, but still learning. I have my own Concord and Cayuga grapes I use. From mid Michigan.
Welcome to Wine Making Talk. . . It is a good day where one can learn something new.
There are a number of folks from Michigan who have posted on here, ,,,, and I have a number of the Minnesota hybrids, being on the other side of the lake.
