Bottled at 100 proof, slightly higher than the standard Single Barrel Select, Jack Daniel's 'Chicago' Single Barrel from the Tennessee distiller's 'Personal Collection' is another formidable release that showcases the caliber of JD whiskey craftsmanship and the unique approach to distilling single-barrel whisky. A standout that compares to any of the finest single-barrel releases, the 'Chicago' is a classy and considered Tennessee whiskey.
