I'm not sure if I got a bad bottle, or if it's true of this brand in general, but when I made mixed drinks with this Whiskey substitute, there was an unpleasant aftertaste that I haven't experienced in competing products. I tried drinking it neat to make sure it was the Kentucky 74 and not one of the other ingredients, but no, it was definitely the Kentucky 74.
Overall it's not terrible, but for something that's this expensive, I'll stick with other brands that seem to have a cleaner recipe.
