Maker's Mark Kentucky Straight Bourbon Whiskey - 84 Proof

In early 2013, Maker's Mark announced that it would reduce the proof of its flagship bourbon from 90 proof to 84 proof in response to growing demand and limited supply. The decision was met with widespread criticism from consumers, and the company reversed its position just days later, keeping the bourbon at its original 90 proof.

Because the change was short-lived, relatively few 84-proof bottles reached the market. These bottles have since become sought-after by collectors as a unique reminder of one of the most notable product reversals in modern bourbon history.
