Bomberger’s Declaration Distillery Bourbon is a robust Kentucky Straight Bourbon Whiskey, bottled at 108 proof with a broad spectrum of distinctively rich characters. It is matured in special barrels, some of which were made from Chinquapin oak that has been naturally air dried for over 3 years. The distillery honors the legacy of the former distillery known as Bomberger’s in the 1800s and later as Michter’s in the 20th Century.
