Created by taking Jack Daniel's standard Tennessee whiskey (also known as No. 7) and then "double barreling and double mellowing" it - meaning it enjoys an extra maturation period in maple wood before being double charcoal filtered.

its very smooth but seems to have lost a bit of its JD flavor. I definitely prefer Single Barrel or even Gentlemen Jack
Just purchased in cozumel, mexico last week. Took my first sip tonight and ...wow! I love orig. JD and this is a smooth, refined sipping version of the original. Even my husband, who is a scotch drinker, was wowed by it. He doesn't like to drink Tennessee bourbon but was impressed with how smooth no. 27 gold was. I am so glad I splurged in the duty free shop and brought home a bottle!!
Good whisky
I found this to be somewhat disappointing. On the one hand, JD have done a fantastic job at creating what I would consider to be their most refined whisky yet, and so for this reason I do not think its price is unreasonable. However, its mellow flavour and smoothness really leaves it too far removed from what I consider JD to be. It is almost flavourless compared to the full flavour one expects of JD, and the fact that it is so smooth also detracts from the JD brand. I like a smooth whisky, but I want just a little roughness when I drink JD. In summary, JD have done a masterful job at creating a smooth, mellow whisky. I just think they've done too good a job - very easy to drink, but just not enough character left to know this is JD once it is out of the bottle.
