PPBart,
I don't have a proven recipe for Port using muscadine but I did have a couple of questions. What type of grapes did you use for the muscadine wine (Noble, Carlos, etc) and how did the wine come out either this time or on previous years? Thank you.

My winemaking partner has a small vineyard with the following varieties:
(Black) Black Beauty,Supreme
(Bronze) Ison, Darlene, Fry
In my backyard I also have a few vines (Darlene and Fry).
Since the quantity of grapes we harvest annually (after the deer, birds and bumblebees get their shares) has been relatively small (2009 yielded a record ~200 lbs) we always simply combine all into the batch. End product is a medium rose, good legs. 11-12% ABV, semi-sweet (SG 1.005 - 1.010), that ages well for at least 3 years (we haven't held on to any of it longer!).
There are several labels of commercial muscadine produced/marketed here in SE Louisiana, and ours is definitely better than any of those (not just my opinion; we've had blind tastings several times at BBQ's and holiday parties and ours almost always comes out tops).
