At what point do muscadine vines begin to taper off in production?

Our family has a set of muscadine vines that are about 35 years old. They are prolific when pruned yearly. How long should I expect these vines to produce before we cut them down and replant? I saw your video where you pruned 50-year old vines. At what point do vines begin to taper off in production?

There's no particular age at which point vines begin to taper off. As long as they're maintained well, they can live to ripe old ages. The oldest scuppernong, known as the "Mother Vine" growing at Manteo, NC, was estimated to have been over 400 years old. I think it died fairly recently.

Sometimes even with annual pruning, the vines can become overgrown, so need to be renovated, cut back real hard to remove some or most of the old "spurs that" that have grown to look like antlers. You'll lose some production in doing so. I'm in the process of doing some of that now. Some are going strong. I'm removing a few unproductive vines. It's possible that some unproductive vines cut down to the ground will re-sprout from the trunk and give you a fresh, new, productive vine from the old roots.

The vines can certainly outlast the trellises they grow upon.

What is the difference between a Muscadine and Scuppernong vine?

What is the difference between a Muscadine and Scuppernong vine?  ...Would you suggest I do my major pruning now?
 
Scuppernong is one bronze/white variety of muscadine grape. It was 
discovered as early as the 1500s by explorers. Eventually, it was rediscovered in the 1750s growing near the Scuppernong River in N.C. Consequently, bronze/white varieties became known as scuppernongs and black or 
purple varieties known as muscadines, but that is incorrect. There are 
many varieties of bronze muscadines. All scuppernongs are muscadines, but not all muscadines are scuppernongs.

You can do your major pruning now. Try to be done by the time new 
foliage begins to emerge.
