When you think of Kentucky, what immediately comes to your mind? The Kentucky Derby, beautiful horses, big hats, right? But what’s the other “icon” that Kentucky is famous for? Yep, you’re right. Kentucky Bourbon.

Bourbon hearkens back to at least the 1840’s and has been called “America’s Native Spirit.” What exactly makes bourbon bourbon? Well, according to Michael Veach, Kentucky historian and bourbon ambassador (yes, there is such a job,) there are six standard rules:

  • It must be made in the U.S.
  • It must be aged in new, charred white oak barrels.
  • It must be at least 51 percent corn.
  • It must be distilled at less than 160 proof (80 percent alcohol by volume).
  • And, it must be entered into a barrel at below 125 proof.
  • Lastly, there can be no artificial coloring or flavor. The darker the bourbon, the higher the alcohol content.

Where does the name bourbon come from? Bourbon ambassador Veach says that he’s not sold on the local story that it derives from Bourbon County—once part of a larger expanse known as Old Bourbon—in upstate Kentucky.

Instead, he believes that yarn about the Tarascon brothers from Cognac, France. The brothers knew that if Kentuckians put their whiskey into charred barrels they could sell it to New Orleans’ residents, who would like it because it tastes more like cognac or ‘French brandy.” They were right, and people started asking for “that bourbon whiskey.”  

To this day, people claim that the area’s excellent quality limestone filtered water and extreme weather patterns are why Kentucky bourbon tastes the way it does. That and amazing distillers who benefit from the use our high purity diatomaceous earth filter aid, PurifiDE® XG.

Master bourbon distillers in Kentucky are meticulous about their hand-crafted bourbon and with good reason. It takes years to distill and mature the best bourbon in the world. They craft to taste, not time. Preserving that taste, color and clarity are key, and they’re not scrimping on anything to make the final product less than perfect. That’s why they choose PurifiDE XG diatomaceous earth filter aid.
