Liberty Pole Single Barrel High Rye Bourbon, available for $70, features a mashbill of 51% bloody butcher corn, 40% Pennsylvania rye and 9% malted barley. It's bottled at varying proofs.
I'm thrilled to see distilleries like Liberty Pole being willing to eschew the temptation to maximize their proof gallon production and explore the time-old tradition of low barrel entry proof. This is the way whiskey was made pre-prohibition and why you'll find ardent enthusiasts like myself celebrating the return of such practices.
