Ah, yes. Most blue/purple dyes will change with acidity. So, I guess the
vinegar in mustard probably helped turn the juice bluer (while a base would
probably have helped turn it to the red side). At least, that's true for
blueberries, red cabbage and wine stains, so I'm guessing it will work for
grape too!
