I have been processing Concord grapes about mid September in Zone 5. The grapes taste sweet when the skin is broken, but the juice is slightly bitter. This year I left picking until near the end of September, and found the juice to be sweet with no bitterness. Conclusion pick Concord grapes in late September in Zone 5. The juice is perfect. IMO. Just an observation.
Durgan, do you process the the juice for an hour under pressure? The (US) National Center for Home Food Preservation recommends a hot water bath for 5 minutes for a quart jar and doesn't say anything about pressure canning. I do my grape juice in a pressure canner set at 6 psi for 5 minutes, and that works well. You probably could reduce your processing time.
I do all vegetable Pressure Canning at 15 PSI for 15 minutes. SLURRY. Experiment has indicated it works. Safe and convenient. Several thousand times used and I am alive ad healthy. Never had any spoilage and ingest some daily.
