The countdown is on Kentucky Peerless Co. has announced the June release of their first Kentucky Straight Bourbon Whiskey in over a century.\n \n Peerless reopened its doors in 2014, reviving a brand last seen before Prohibition. They laid down their first barrels of bourbon over four years ago, and next month the bottles will finally be ready to hit shelves.\n \n Master Distiller Caleb Kilburn used a sweet mash process and non-chill filtration to craft this landmark release for the brand. Most bourbon on the market today is sour mash cooked with a bit of already fermented grains (and the consistent yeast and bacteria included) from a previous distillation cycle. In contrast, sweet mash bourbon uses a freshly cultured batch of yeast each time.
