doubling a recipe

[enyawgerg]

I am doubling a recipe of concord wine from fresh grapes. I am in the 12hours leading up to adding the yeast. As I look into the Primary, it does not look like the 2 gallons that it should. Granted the bag of crushed fruit is large and does contain a bit of juice. When I lift out the bag it looks as though it is just a little over a gallon. I followed the recipe. Am I to assume that I will get two gallons of juice from this once I drain the crushed fruit off?

Once you press the grapes, you should be fine. Be aware that 2 gallons of must does not make 2 gallons of wine. You are going to lose around half a gallon to lees and samples.
