Approximately how many bottles are produced from one ton of grapes?

• A. 720
• B. 600
• C. 1000
• D. 800

Answer: (A)

The idea being tested is estimating wine yield from grape quantity using a standard industry rule. Roughly one ton of grapes yields about 150 gallons of wine. A 750 ml bottle is 0.75 liters, and there are about 3.785 liters in a gallon, so one gallon gives roughly 3.785/0.75 ≈ 5.05 bottles. Multiplying 150 gallons by about 5.05 bottles per gallon gives around 758 bottles. In practice, losses during pressing and processing reduce this a bit, so a common rounded figure is about 720 bottles per ton. That also matches roughly 60 cases (60 × 12 = 720). So 720 is the standard, practical approximation used in winery education and planning.
