Whatever alcohol is in the juice (a very small amount in the flavoring base) is going to be vaporized and inhaled. You're not ingesting it. You can go into the kitchen and make pasta with Vodka sauce and you're not going to test positive from inhaling the steam from your cooking. Whether or not there is any alcohol in the juice is irrelevant. It's either going to evaporate off during steeping or burn off during vaporizing and not show up in your bloodstream.
