Each case of wine grapes from Chile is 18lbs. Depending on the grape variety, you should yield about 1.5-2 gallons of must per case.
However, keep in mind that certain wine grapes are “juicier” than others. For example, Syrah is considered a “juicer” grape than a Cabernet. If you look closely, you can see the difference in the shape of the berries. The Syrah grape has more of an “egg” shaped berry to it. The Cabernet is more of a circle shaped berry. The berry size, climate, soil, and vineyard practices will all help determine how much juice is produced in each berry, and the berry intensity.
Usually each case of 18lb wine grapes will yield about 1.25-1.50 gallons of finished wine.
That equates to about 7 bottles of wine.
Other factors that influence how much must and/or juice you yield per case:
How your rollers are positioned in your crusher destemmer
How much you press after fermentation is completed
How much wine you loose during racking
If you barrel age your wine
If drink a lot of wine during bottling
