Review [source]:

The Senator is a whiskey made by MGP and bottled by Proof  and Wood Ventures in Bardstown, Kentucky. The brand seems to honor American tradition by finding inspiration in the deep roots of the American political system. The Senator is a 6 year aged straight rye whiskey. The bottle is barrel proof, which means it boasts a higher-than-average ABV.

Aged at least 6 years in new, American Oak. It’s 121.4 proof and 60.7% ABV. Distilled at MGP in Indiana, and bottled by Proof and Wood Ventures in Bardstown, KY. The mash bill is 95% rye and 5% barley. The color is similar to a brand new copper penny, and the liquid is full bodied. The legs are graceful, but not delicate and cascade leisurely down the glass. On first glance this whiskey smells grassy, a little bit dirty. There are some nice complexities, as it opens up, it smells a lot more sweet like a warm cinnamon roll. The high ABV makes this rye feel all tingly all the way down
