Colkegan PX gets its due share of praise in Nicols Stecher's article on the Best New American Single Malt Whiskey's of 2021.
"Although not an official category protected by Appellation of Origin (AOC) laws, the purveyors of American Single Malt are making some of the best whiskey in the United States. Spread across this great nation of ours, these distilleries are not so much defined by location as they are to a code of excellence, and terroir.
The rules are simple: the whiskey must be made from 100% malted barley; distilled entirely at one single distillery; and mashed, distilled (to no more than 160 proof) and matured (in oak casks not exceeding 700 liters) entirely in America. While strict, that platform leaves plenty of room to play and experiment — and that’s what these distilleries are doing."
