How many pounds of grapes per vine of Barbera in Sierra foothills

I have planted 70 Barbera and 30 Zinfindel in the Sierra foothills. These are 2
to 3 year old roots. They are planted in fairly rocky soil on a slope facing
southwest. How many pounds per vine should I get after mature? How many
gallons of wine?
