Keeping up with the Tivolis

This is our grape harvest. Tivoli and Spousie harvested theirs in four hours. This bucketful took us two about 35 minutes. Partly because we're not very experienced and partly because we forgot about them until after dark so they were rather hard to find on our unpruned and unkempt vine.

Does anyone have any recipes for sour grapes? (No, that's not a metaphor.)
