Barnivore Editor's note: May 2011
Since the first email sounded like they aren't vegan friendly and the first check they weren't vegan friendly. We sent a follow up to triple check... and have yet to hear back. If you are interested in this wine, please send them an email, then forward us the correspondence."

MJ's reply:
"I am not sure I understand your answer; do you use the milk / gelatin /other animal base products during processing?."
