Jack Daniel’s Sinatra Select is bottled at 90 proof and gains its rich character from specially crafted “Sinatra Barrels” mingled with our classic Tennessee Whiskey. The Sinatra Barrels are handcrafted with the addition of deep grooves on the inside of the barrel staves. This exposes the whiskey to extra layers of oak which imparts a rich amber color, bold character and a pleasant smokiness, followed by an incredibly smooth vanilla finish. The smooth, bold character of the whiskey embodies the smooth, bold character of the man himself, Frank Sinatra.
