Vineyards generally produce between 2-10 tons of grapes per acre.
1 ton of grapes, when crushed, yields about 2 barrels of wine. Normal wine barrels hold 60 gallons of wine each.
60 gallons of wine produces about 25 cases of wine (12 bottles per case)
1 acre of vineyard can produce an average of about 12 barrels of wine. Which produces 300 cases, or 3,600 bottles of wine.
Normally about five, 5 oz glasses of wine in a standard 750 ml bottle.
3-10 clusters of grapes (about 600-800 grapes) are needed to produce one bottle of wine.
