Mystery Malt (Macallan) 16 Year Old 2009 Signatory Un-Chillfiltered for TWB

The Secret Speyside 16 Year Old 2009, bottled in January 2026 by Signatory Vintage exclusively for TheWhiskyBarrel.com, is a rare and powerful single malt distilled at the famed Easter Elchies estate yet released discreetly under the Secret Speyside label.

Drawn from a single bourbon hogshead (#156) and bottled at a formidable 61.6% ABV, this un-chillfiltered release offers a pure and unadulterated expression of one of Speyside’s most revered spirits. Bourbon cask maturation allows the distillery’s elegant, fruit-forward character to shine, layering citrus, vanilla and orchard fruit over a rich, malty core.

Presented with a striking gold label, this bottling is a fitting tribute for any British spy fan, subtly nodding to the whiskies iconic on-screen appearances and celebrated association with the world’s most famous secret agent—an elegant wink rather than an overt statement.

With an outturn of just 277 bottles, this is an exceptionally limited release and a sister cask to a previous TWB-exclusive bottling—making it a highly desirable addition for collectors and enthusiasts alike.
