16 Year Old Pot Still The gold foil was the final original bottling of the Hirsch 16, prior to the recent humidor bottle. According to many, A. H. Hirsch Reserve holds the crown for most expensive bourbon on the market. The 16-year old spirit was distilled in Michter's Distillery in Schaefferstown, Pennsylvania, in 1974, then, as is the tradition of many parents, left it in the distillery to mature until bottled in 1990. A. H. Hirsch is a staple in American bourbons - legend has it that the day before Prohibition struck, the line of people waiting outside Michter's Distillery wanting to fill anything that could hold liquid with the last rations of legal whiskey, was two and a half miles long. Those were the good ol' days, though, and no longer can a guy run by the distillery to fill an old soup can up with bourbon before work.
