From the linked article:
The bottles, with labels designed by artists Sir Peter Blake and Valerio Adami, were bought by an international businessman for his private collection for US$600,000 each, setting a new record for the most expensive pair of whisky bottles sold.
The spirit was distilled at Macallan in 1926 and matured for 60 years in ex-Sherry casks before being bottled and released in 1986.
I’d love the chance to sample a dram from one of these bottles, but I would never consider buying one (even if I had the money). It’s just too much and I am certain the whisky inside isn’t that good.
