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."

Sazerac Straight Rye Whiskey is rumored to be made from a mash of 51% rye, 39% corn and 10% malted barley. Following distillation, the whiskey is aged for a minimum of six years in the Kentucky heat, before a small batch of barrels are married together. The whiskey has a copper-bronze color, along with an aroma of rye, malt, cinnamon, cloves and black pepper. The aroma gives way to notes of chewy caramel, vanilla, spicy rye and candied citrus on the palate, and ends with a touch of dried fruits and rye. Sazerac Straight Rye Whiskey earned a score of 94.5 points from Jim Murray's Whisky Bible, and a score of 95 points from Wine Enthusiast, which called it a "Best Buy." In addition, it earned the Best American Rye Whiskey Award at the Los Angeles International Wine & Spirits Competition, and the Gold Medal at the San Francisco World Spirits Competition.
