Atop the "double aged" range sits the 25-year-old expression, the oldest and rarest in their permanent lineup. It's aged at least 25 years in oak casks. It is then blended and finished in casks that used to hold Royal Brackla, letting the flavors and aromas marry. The finished whisky has a smooth, creamy, and rich profile with honey and nutty notes and is bottled at 80 proof.

Johnnie Walker Blue Label Blended Scotch Whisky represents the epitome of blending and the pinnacle whisky of the House of Walker. The blend was personally created by James Beveridge, Johnnie Walker's Master Distiller, and is crafted to reflect the style of whiskies produced by Johnnie and Alexander Walker in the 19th century. "I think of blending as being like the process of writing," says Beveridge. "Is the final book just a series of words, a lot of facts and information, or has it been put together with care and attention so that the end result will relate to the person who reads it? If it does, then that, you could argue, is magic blending, like writing, like any creative process, is much more involved in the world of ideas, with trying to connect with the whisky drinker. I like to think that we have made that connection."
