To be honest, Jack Daniel’s does a good job of describing what Sinatra Select is, so see above for the information straight from their website. All I can really add is that a few other whiskeys, such as Jefferson’s Twin Oak, have experimented with adding grooves into the barrel staves to impart additional oak character. Since I haven’t had the Twin Oak, I can’t comment on how good or bad it is. With the Sinatra Select though, I am optimistic that it will do wonders because Jack Daniel’s Old No. 7 and Gentleman Jack are just not for me. Let’s raise a glass to Frank Sinatra and learn more about his whiskey (not actually but in spirit maybe) in this Jack Daniel’s Sinatra Select review.
