Bad computation

Postby Bruce53 » Mon Oct 03, 2011 11:18 pm

Problem: Figures at crush time do not fie. We carefully weighed a gross 360 lbs of merlot grapes, including stems and containers, and a net of 320 lbs of must. Using 6.25 gallons of must per 100 lbs of grapes, we figured we would have 20 gallons of must. We got 35 gallons, 33 gallons in a 33 gallon RubberMaid trash can plus two gallons. [We then removed ten gallons from the trash can to another container to allow for the cap.] Anyone with a possible explanation of the gained 15 gallons? Many thanks…

Where did you get the 6.25 figure? It could be the difference between must with pulp and skins and must without pulp and skins.

Not sure where I read it. That is a good point. Will investigate. Thanks...

No problem. My rule of thumb when making wine from grapes is allow 50% extra room for pulp. So, If I am making 60 gallons of wine (finished) or about 26 boxes at 36 lbs each, I will use a fermenter that accomodates 120 gallons.

thanks
