What's the matter Al, are you ending up with more grapes than expected?
A word of caution to you...........
The plastic barrels (the blue or even white food grade ones) are not sufficient for long term storage safely. Stay with glass, stainless, barrels or even the real flex-tanks. Be sure they are topped as much as possible also. I opened two blue barrels recently and much to my dismay, the one with Leon Millot was horribly oxidized. The other had St. Pepin in it. It has slightly oxidized- has a darker golden color than ones stored in glass and has a little bite on the tongue. The Millot went down the drain. The St. Pepin went into glass and I will see if it will be salvageable or not.
