I tasted the grape juice on Thanksgiving (and coerced some others into sampling it with me), serving it in the very same glasses Grandmother used to use.
As I unsealed the mason jars, I had my doubts there would be any taste to these juices at all, especially the white grape juice. As you can see, it had none of the color found in store-bought white grape juice.
Lo and behold, it turned out the “blush” grape juice was the variety with next to no flavor — the blush variety comes from the Suffolk table grape — really, it tasted more like sugar water. The white grape juice, on the other hand, had a nice full flavor, recognizable as grape juice. We’re not sure what the grape is, but someone in the tasting room suggested Muscatel.
