GTS is a remarkably unique bourbon whiskey - bottled at full barrel strength (barrel proof), uncut, and unfiltered, ranging from 15 to 16 years old (depending on the release).
Since its first appearance on the market in 2002, it has unfortunately gained a cult following and due to its limited bottling, and consequently it is now extremely hard to come by (for mere mortals, that is).
You have to be in the right place at precisely the right time, or pay an exhorbitant premium on ebay. Now if you lived in Kentucky, or were lucky enough to be there during the time of its release, you could drive to all the liquor outlets possible and buy it up by the 6-bottle case. I suspect this has come to an end, many retailers will only sell a 2-bottle maximum to any one customer, in an attempt to help spread it around. Ocassionally you can purhase it in a bar in Kentucky for approx. $20 a glass.
You have to realize that with a unique product of this nature, finding or creating more supply is simply impossible.
Having enjoyed both the 2002 and 2004 expressions, I would have to say that it is by far the most exquisite spirit to ever pass this humble mortal's lips.
Jim Murray (love him or hate him) claims it is his favourite whisk(e)y and in the past has rated it tops in the world.
