High N' Wicked Kentucky Straight Bourbon Whiskey

Sour mash is ubiquitous, sweet mash is not. Sour mash whiskeys are made utilizing backset - a by-product from previous distillations that reduces the overall pH level - thus “souring” the mash. This creates an acidic environment that helps to limit bacterial growth, and creates a degree of consistency between batches. So why would you want to do anything different? Flavor.
