what is the difference between kentucky bourbon and irish whiskey?
When it's bottled, the spirit has to be at least 80 proof. Also, bourbon can't contain any added flavors or coloring. ... Irish whiskey must be distilled from a yeast-fermented mash of cereal grains so that the distillate retains traces of their flavor, and it must be distilled to no higher than 94.8% ABV (189.6 proof).
