This is no ordinary release, this trifecta includes 100 barrels, bottled at 100 proof, celebrating 100 years since Frank’s birthday. The Chairman of the Board Centennial selection bottles will be individually numbered. As with previous releases, the whiskey enters specially selected “Sinatra” barrels hand-picked by Master Distiller Jeff Arnett. In those barrels, the liquid is exposed to extra layers of toasted oak through a grooving process only done at the Jack Daniel’s Cooperage. This allows the ultra-premium whiskey to achieve a pleasantly smoky and rich oak aroma that Sinatra was known to adore.
