Boulder Spirits Bottled In Bond American Single Malt Whiskey follows the 1897 US Bottled-in-Bond Act, requiring the whiskey to be distilled in one season by one distiller at one distillery, aged at least four years in a bonded warehouse, and bottled at exactly 50%. Boulder Spirits was founded by Scotsman Alastair Brogan, who moved to Colorado in 2011 and started the distillery as Vapor Distillery.
