Maybe not the only one in North America. I know of a few, one in the States and one near here that feed wine and alternatively Apple Cider Vinegar. Not sure if it is about PH in the ruman or what but his grass fed wine fed beef is pretty tasty. Little Bow, I bet your single malt would have the same effect. It would help to be in wine country and be able to buy batches gone wrong by the tanker load.
