Johnnie Walker Blue Label King George V

This ultra-delux blended whisky, packaged in a distinctive square 75cl glass bottle, celebrates the first Royal Warrant granted to John Walker & Sons to supply Scotch whisky to the British Royal Household in 1934. Only whisky from distilleries operating during the reign of King George V have been used to create this blend - some from stocks dating back to the early 20th century and many from distilleries which no longer exist. "The blend is so rare it is only available on special allocation," said Jonathan Driver, brand ambassador for Diageo.
