This rumination was inspired by a bottle of Jack Daniel’s Old No. 7, though not in the way you suspect. In an era driven by the notion that success depends on relentless innovation, upgrading and restyling, I was wondering what might happen to a new hire at Jack Daniel’s who suggested that the sour mash whiskey’s distinctive flavor be modernized with some fresh, citrus accents and that the old fashioned square bottle with its historic label should be upgraded to a cleaner, more contemporary look. I think we can safely assume the new guy would get the boot.
