We’ve just finished harvesting the grapes. Like most everything else in the garden, they took a very long time to ripen because of the cool summer weather. We tried to leave them on the vine as long as we could so they would sweeten up, but when the raccoons (or maybe opossums) started eating them, we knew they were ready and should pick the rest.
We put the best bunches in the refrigerator and made raisins out of the rest. The hardest (tedious) part of making raisins is picking them off of the stems. It’s a good activity to do when you’re watching TV or listening to the radio. Wash the grapes and throw away any moldy or otherwise funky ones.
Even if the days here are hot where we live, the nights cool down to much to successfully make raisins outside. I’ve tried on several occasions without success so now I use a dehydrator.
Then, in about 24 to 36 hours, you have raisins.
