Though Prohibition ended 75 years ago, a lot of the era's laws stayed on the books. This past summer the legal situation changed in New York, enabling auction houses to sell items like whiskey and cognac.
A single bottle of MacAllan Scotch, distilled in 1926 and aged 60 years before being bottled, is expected to bring as much as $30,000 at auction. Why?
"Low production, one single cask, rarity," Brierly said during the CNBC interview. "Patience costs money."
A bottle of what's called "George Washington's whisky" is expected to draw a final bid of between $10,000 and $20,000.
"Produced in 2002, but following the exact recipe of George Washington -- using modern-day techniques, yes, but with a nod to the Old World style," explained Brierly.
