I also prefer golden raisins and, my Thompson Seedless grapes as well as my champagne grapes make great raisins, not quite as early as you want, 2- 4 weeks later.
The Thompson make sweeter raisins but, the champagne though more tart don't have that Concord odd taste.
For me the Thompson are more prolific, but the champagne have denser bunches.
Both, when barely starting to ripen also make a wonderful, slightly tart jam that I enjoy and, at that point a good dry wine as well, wait for them to get fully ripe if you want sweet wine.
