Saw you're from Tennessee, Cecilias9. Where from? I live in the Columbia area south of Nashville and will have my first crop of muscadines this year. Actually got interested in muscadines (had never heard of them before) by watching Waldo's video a number of years ago.
Planted 4 vines three years ago and one got winter killed the first year. This year, though, the three that made it through have a LOT of grapes on them which are just starting to ripen.
Getting a brix on the few I've checked after picking from 18 - 23. From what I've read this is fairly normal, but wonder what others have seen.
