The Macallan are releasing The Royal Marriage, on sale from 11th April 2011. This is a limited bottling, there are only 1,000 bottles, selling at £150 each.
The website says its sold out already. This event was always going to be a ka ching moment for collectors/investors/whisky touts. Well done to those collectors/investors that got one. My guess is that if you bury it for a decade, it'll be worth over £1k when you exume it.
