Courtesy G. Hodder I have a September, 2010 bottling of Silver Select. This particular one is quite untypical of Jack Daniels in my experience. It has no banana-like notes - zero. It is on the light side, a little astringent, with some black cherry notes. Water brings out the taste.
In discussing the bottle with him, the question came up, was Silver Select, i.e., the 100 proof form of Jack Daniels historically exported to Europe and elsewhere, and presumably similar to the pre-Prohibition Jack Daniels, always a single barrel? If not, was it bonded? When did it change over, if at all, to a single barrel? As far as I can recall, and I've been buying it for about 10 years, it was always a single barrel but over this same period, the domestic, 94 proof version of JDSB has been available and so they seemed to go in parallel except the export was the traditional 100 proof strength.
