Grape must volumes

[Cellar_Rat]

Here's tricky one.

If I what to end up with 300 liters of finished wine, what is the must volume. Or put another way what % do you loose at press time.

ooooo

i reckon on one box of grapes netting me 4.54 litres of finished wine...

so 66 boxes....never really measured the volume of must....

[lockwood1956]

although having said that.....

I split 5 boxes of grapes between two 33 litre fermenting buckets, and that seemed to be a reasonable fit
