A new one from High West, I got to taste this unaged rye at a trade show recently and found it pretty spectacular. The OMG stands for "Old MononGahela" as in the Pennsylvania river that runs through the original American whiskey country. A bit silly name, but it's a fun story. The whiskey itself is 100% rye - 20% of it malted. And this supposedly contains all the head and tail, no cut, in honor of the good old ways (1800s).What I really liked in this was a very present yeastiness on the nose especially, almost like a champagne yeast. David said they use three types of yeast, and had played around with the right balance of them. It may be unusual, but I think it plays really well with the rye spice. Very interesting stuff, eager to buy a bottle and spend more time with it once it comes out, which is rare for an unaged whiskey for me.
