This is as good a time as any to log this little nugget in. One of the Warehousemen at 4 Roses told me, and he should know, that it depends on the barrel how much is lost to the Angels. He said sometimes a barrel will go in with 53 gallons and come out with 52. Some barrels will lose along the lines credited to Elmer above. Here's the funny part, some will be empty, and they have found barrels that have completely collapsed in the rack. The main point was that there isn't a single answer, I guess once one deals with millions of barrels an average can be arrived at. Does it help to know that no matter what the loss is , we are paying for that too?
