Jack Daniel's Single Barrel is made by the same process as Jack Daniel's Old No.7 but tends to be aged for 5½ to 6 years (certainly never less than 5 years and occasionally as long as 8 years).
On average Single Barrel is aged some 18-24 months longer than standard Jack Daniel's No.7, although no age statement is shown on the bottle.
The barrels selected for this Single Barrel are drawn from the top racks of the warehouse where, due to larger temperature variations, the ageing effects are greater.
Each bottle of Jack Daniel's Single Barrel has a neckband indicating the barrel number, bottling date and rack location. (The still square bottle was made shapelier with a 'less is more' label with new packaging introduced at the tail end of 2009.)
Jack Daniel's Single Barrel bottles vary in style, according to the cask they are bottled from. They all have the same core profile, but some are far more elegant and mellow than the standard No.7 with rich vanilla, honey, gingerbread, cocoa, espresso, spicy oak, cooked fruits and orange marmalade. Others are more oaky. The folk at Jack Daniel's say, "Single Barrel is aimed at adventurous drinkers open to exploring."
If you buy a whole barrel (some 240 bottles worth), the distillery will allow you to choose your preferred cask, "the one that speaks to them." Jack Daniel's will then custom bottle it and send you the empty barrel with the bottles.
Review and Tasting
Sampled on 17/05/2016
(sample barrel 15-3539, bottled 28/Jul/15) Clear, rose golden, amber.
Buttered popcorn with whiffs of almond oil, vanilla, cigar/cedar wood and a touch of bitumen and green apple.
Dry and slightly smoky with demerara sugar, dark brown toast, salty buttered corn-on-the-cob, white chocolate, hazelnut and sweet cinnamon spice.
Dry with more salty char-grilled corn-on-the-cob and lingering cinnamon and black pepper spice.
Jack's Single Barrel bottlngs vary greatly but salty char-grilled corn-on-the-cob and faint white chocolate seem to be commonalities. The best have have rich vanilla, honey, gingerbread, cocoa, espresso, spicy oak, cooked fruits and orange-marmalade.
