Well I have one empty Secondary

I added the yeast last night to the grape must. I checked it out this morning because I couldn't see any noticable airlock activity. Opening the lid I saw a layer of foam on the top, so the yeast is going at it. The last time I made this, it had to sit for close to 3 weeks in the primary. Well I have to push down the ferment bag at some point.

The problem is that I wanted to start the elderberry wine from the dried elderberries I bought yesterday, but I don't have a free gallon fermenter until I bottle the passion or the first batch of grape wine, neither have cleared yet. Both are still as yet unnamed.
