The Jack Daniel Distillery made minor refinements to the familiar Jack Daniel’s Old No. 7 bottle to accentuate the bottle’s square shoulders and also to simplify the front and side labels. The distillery says that through the years, as refinements have been made to the bottle and label, the label began to look more cluttered. The current refinements are meant for the bottle to reflect the distinctive character of the whiskey. The bottle began shipping last month and will be on most shelves by July.
