Picked up a bottle of this in Amarillo on our way home from vacation in Colorado. I'm more a fan of KY-style ryes than the MGP 95% (can't stand that MGP dill flavor), with RR SiB and WFE 4-year being two of my favorites. I've also been a big fan of the last couple of Master's Keep releases, so when this Cornerstone Rye was announced I knew it was something I wanted to try. Nose - baked apples, oak, leather, a hint of butterscotch, and some of that earthy WT funk. Greener notes of rye spice are lurking underneath, but they're subtle. No noticeable heat/ethanol on the nose. Palate - Rich mouthfeel with toffee and baking spices up front, then it transitions into mint, buttered rye toast, and some faint pepper and oak on the long finish. The rye flavors are stronger that I would have expected given the nose. All in all I'd say it's an excellent rye. It has bolder rye flavors than I expected from a "barely legal" rye, and plenty of depth and complexity from the extra aging. It's hands-down better than the standard RR SiB rye IMHO. Whether it's worth 3x the price is a slightly tougher call. The $129 price point of previous MK releases would have been more appropriate to me, but I guess it's just the reality of the current market that prices keep escalating. Bottom line, if you're a fan of rich, well-aged ryes, or just older/premium WT expressions in general, this should be right up your alley.
