[4/29/15] This is what Jack was intended to taste like. Stronger barrel taste adds legitimacy and strength to the flavor. Not too much proof but a slight bite with hidden sweet and rash sour. [4.17.2016] An updated test on new bottle agrees. The stronger proof benefits the bottling (and drinker) with less dilution of flavor. More charcoal and sooty, earthiness combined with stronger barrel flavors. Without these Jack Daniels isn't very special.
