How Many Grapes to Produce a Bottle of Wine?
Determining the yield of harvest in terms of the number of bottles of wine is a lengthy, but interesting process. First the yield must be determined by weighing a few different clusters of grapes to obtain an average weight. Then the number of clusters per vine is estimated and the number of vines is determined. By multiplying this information, one can determine the approximate number of pounds of grapes in the total yield, which is estimated in tons or a fraction therof. One ton of grapes can yield between 130 to 150 gallons of juice. Downsizing the weight measurement – it takes between 13 and 15 pounds of grapes to make a gallon of wine. Storage tanks are normally measured in liters but are also converted to gallons. Approximately five 750 ml bottles make up a gallon. Thus, a 500 gallon tank of wine should produce about 2500 bottles of wine.
