Michter's Pot Still Sour Mash Whiskey, which was the company's most popular expression before it declared bankruptcy in 1919, is made in accordance with original sour mash tradition. By using sour mash, which refers to the art of using a small amount of spent mash from an older batch of whiskey in order to catalyze fermentation in a new batch of whiskey, Pratt is able to maintain consistency with each bottling. While Magliocco readily admits that he wanted to pay tribute to the original Michter's Sour Mash, which was comprised of a mash of 50% rye, 38% corn and 12% barley, the current release isn't an attempt to reproduce it exactly. Rather, it was inspired by the older version, but with the intention of improving it. "If it was like everything else," says Magliocco, "we wouldn't have released it."

New Riff Distilling's core Rye whiskey is full-bodied, offering hugely spicy character. Building upon America's 1897 Bottled-in-Bond Act—already the highest quality standard for aged spirits in the world—New Riff Rye is Bottled In Bond Without Chill Filtration. Featuring a unique mashbill of 95% rye and 5% malted rye, it represents a new riff on our hallowed local Rye whiskey traditions. Aged four years in full-size 53-gallon toasted and charred new oak barrels, there are no shortcuts taken in its traditional production. All New Riff whiskeys are made with the full sour mash Kentucky Regimen; all carry an age statement and are always bottled without chill filtration. Our distillers learned the black arts of the hardest whiskey in the world to make—the famed 95% Rye—under the direct tutelage of the distiller who mastered it in Indiana, Larry Ebersold of Seagram's. Taking Master Larry's instruction in hand, we put a riff on it to the tune of adding 5% malted rye, a unique twist that aids in pulling additional flavors out of the rye and adds a touch of the elegance of malted rye.
