How many pounds of grapes , do I need to make a demijohn of wine ?

 

[Johnd]

Depends upon the size of the demijohn. Generally, 3 lugs of grapes (108 # total) will yield 10 gallons +/- of must, and 6 - 7 gallons of finished wine.

My somewhat conservative numbers are 15.5 lbs of grapes per gallon red, 20 lbs per gallon white, post gross lees racking.

Exactly.

And since, during racking, one will loose volume, one either needs different sized demijohns, or a lot of marbles.
