I grow, in order of quantity, Delicious, Tara, Ison, Triumph, Eudora, Majesty, Darlene, Supreme, Unknown, and Big Red. For those of you scratching your heads and thinking WTH? Yes, Heck. These are muscadines, native to the southeastern U. S. The source of America's first commercial wine. They haven't been bred and selected for thousands of years for winemaking, so they don't compare well to vinifera grapes for winemaking, especially if the standard used to compare is vinifera wine. They have 40 chromosomes as opposed to the 38 in all the other grapes. Yes, that make viniferas the retarded cousin. I grow them because they are immune or resistant to most grape diseases, fungus, and insects. I have never sprayed insect spray or fungicide on them. I have a couple of producing vines that are not on trellises. Just growing there on the ground. Right next to the dirt, bugs, humidity, etc. They are also not bothered by squirrels or birds. Opossums, skunks, and raccoons are the only serious predators I'm likely to encounter. Muscadine vines produce from 40 pounds to 200 pounds of grapes per vine and prefer a spacing of 20 feet. I didn't start growing them for the purpose of winemaking, but saw that as a means of preserving the fruit for year round consumption. They are one of the superfoods (I also grow 2 other superfood berries I make wine with, elderberries and aronia.) I have somewhere in the range of 60 vines.
