Rabbi, do you know about
Gan Eden Winery? The owner is an observant Jew and an old ASC cigar fan whom I've enjoyed smoking with, and he makes some awesome kosher wine products. I think he stopped labeling them as "kosher wines" because they're much, much better than the usual range of what is marketed under that name, and it was killing his sales. But he is definitely an
observant Jew and makes his wines according to proper procedure. Tasty stuff, too.
