Whether a bourbon is worth about $50 (or more, sometimes a lot more) or not, is a personal 'value' choice. Speaking for myself, I am glad they are on the shelves. As a general rule (for me), I think they are noticably better than most $30 bourbons, the exception being (my judgement) Four Roses Single Barrel, which sells in the high $30s around where I live.
I really like different 'styles' of bourbon on different occasions. At times I want something thick, rich, and creamy with barrel flavors. Other times I want something soft and lightly sweet, and at yet other times, I want something robust and spicy. The three bourbons I am about to describe come fairly close to filling that bill.
The first bourbon is a vatting of 40% William LaRue Weller (2005 release at about 121 proof), 40% Wild Turkey Russell's Reserve (90 proof), and 20% Bernheim Wheat Whiskey (90 proof). The final proof for this whiskey is just over 102 proof. This vatting has rich, creamy barrel flavors from the WLW, a good dollop of spice from the WT, and the softness of the Bernheim. It is an excellent whiskey.
The second bourbon is Rock Hill Farms bourbon. This is a premium Buffalo Trace bourbon that sells for just under $50. It is slightly less rich than the vatting and is a bit sweeter, with a mite less spice. It too, is an excellent bourbon and is a noticeably better (my opinion) and more rounded than the regular Buffalo Trace bourbon. Compare the two, regular BT bourbon and RHF and you will note the similiarities........ and the differences. RHF is the best of the barrels of the BT line... there are fewer of them and they rightfully get a higher return.
The third bourbon is Wild Turkey Kentucky Spirit. This is a premium Wild Turkey bourbon that sells for about $50. It has excellent barrel flavors and uses the signature Wild Turkey high rye recipe spice with its 'bite'. It too, is an excellent bourbon, that in my judgement, is a bit richer and less sharp that Rare Breed.
Each of these bourbons has some characteristics that make them stand out. I could, and will, drink and enjoy each of them at one time or another......... without feeling compelling to say which is best........ neither is better, they are different and equally good.
