I’m in Alabama and over 50 years old and have never seen a grocery isle dedicated to grits. So there goes his credibility
Seems to me somebody has watched "My Cousin Vinny" one too many times.
If somebody’s all that worried about variety of grits, they’ll just go to the mill that ground them. Fine, medium, coarse, yellow, white, you name it, and ground fresh right there, from local farmers. We always bought Cherokee brand from the local mill when I was a kid. Getting harder to do now.
