I just finished eating them. I didn't have any apple juice on hand, but did have purple grape juice. That's why the question on purple grape juice. I only spritzed once with the purple grape juice. Then wife found a bottle of white grape juice(you know the juice is actually light yellow) so I used that when I foiled them. Seems like the purple grape juice has a stronger taste than the white. Anyway, THE RIBS WERE GREAT! Will be eating them again tomorrow. Thanks.
