10 vines will yield ~5 bottles of wine (750ml)
This is a tough question to answer because every variety, vineyard and region are a little different.  That said, an average vine will produce about 30-40 clusters.  Each cluster will weigh about 1/3 – 1/2 of a pound.  It takes 14-15 pounds of grapes to make a gallon of juice. There are still alot of variables to consider.  But these numbers suggest that you will yield about 1 gallon of wine for every 10 vines.  There are about 5 bottles of wine in a gallon.
