Had Miller and Croll not stepped in, casks dating back to the 1960s would have disappeared into anonymous blends. Instead, their company, Number One Drinks, released its first whisky in 2006 — a single cask from 1971, priced at £65 a bottle. Even so, one retailer called it a ridiculous amount to pay for a whisky no one had heard of.
But once people tasted it and heard the story, demand took off. Today a 1971 Karuizawa will set you back around £10,000. A vatting of ‘90s malts called Spirit of Asama released in 2012 for £80 now costs about £2,000. In 2020, a bottle of the 1960 vintage sold at auction for £363,000. Miller has now reached the end of his supply; the final release, a vatting of malts from the 1960s through 1990s called Once in a Lifetime, is priced at £19,500. And in March 2026, collector Sukhinder Singh auctioned the last two remaining casks at Christie’s for £4.25 million.
