Bigbendmarine - I never had a muscadine. What are they like ?? Juice looks great !! How's it taste ??
Bowsnbucks, that's a bit tough to answer because so many cultivars have been developed but I'lll give it a try...
The parent muscadine grape is actually native to the southeast United States and has been extensively cultivated since the 16th century, ultimately leading up to over 150 named cultivars -- with cultivars split between those developed for eating versus juice production. Picking cultivars tend to be really large (1 1/4" to 1 1/2" diameter not unusual), INTENSELY sweet, and HEAVILY flavored (MUCH stronger grape taste than eurpoean grapes) whereas the juice cultivars tend to be a tad bit less sweet, smaller, and often with a bit more of a bunching growth habit.
Generally (but in varying degrees by cultivar) they are much thicker skinned than european grapes and have numerous grape seeds. Some studies have pointed to them as being extremely high in healthy antioxidants. I personally chew and eat the skins but the pulp is sweeter and as this video shows even among southerners how one eats them varies.
European bunch grapes do NOT do well in the humid south due to a bacteria that thrives in the hot, humid south that causes what is labeled as Pierce's disease -- fatal to almost all grape species outside of the native muscadine cultivars. On the other hand, many cultivars of muscadines are extremely vigorous having to be pruned several times in a season to keep growth in control.
While I LOVE eating muscadines due to their intense flavor, I've found many of the wines to be sickeningly sweet for my taste and I actually prefer slightly sweet wines to dry ones... but many of the muscadine wines just take sweetness to another level.
The ONE winery that really seems to have gotten it right is Duplin Winery out of N.C. For anyone tempted to sample them, I'd recommend their Hatteras Red, Midnight Magnolia, and Scuppernong wines. Their winery in Rose Hill, NC is a fun place to visit and looks like they have a retail location in North Myrtle Beach now as well for anyone who visits the area. Their wines are pretty easy to find in my neck of the woods (Florida) as their wines are sold at Publix. Outside the southeast looks like it might be fairly easy to find in parts of OH and PA as well.
