For the first time since Bill Samuels Sr. introduced Maker’s Mark Bourbon more than 50 years ago, the whisky is being changed. Supply shortages have forced Maker’s to lower the alcohol by volume (ABV) level from 45% to 42%, which lowers the proof from 90 Proof to 84 Proof. In an interview with WhiskyCast’s Mark Gillespie, Maker’s Mark Chief Operating Officer Rob Samuels explains the reasons behind the move, and why he claims it won’t affect the taste of the whisky.

Editor’s note: This story was published on February 15, 2013. Two days later, Rob Samuels and Bill Samuels Jr. announced that Maker’s Mark would return to 45% ABV strength as of the next day’s bottling run.
