Unnamed Speyside 13 Year Old 2005 (casks 17/A106 58) - Un-Chillfiltered Collection (Signatory) 70cl Whisky

This secretive Speysider hails from a mystery distillery, though we do know that it was distilled in 2005. It spent its 13 years of ageing in a hogshead cask, until the single malt was bottled up by Signatory for its Un-Chillfiltered Collection at 46% ABV. Perhaps you can use your powers of deduction (and taste) to figure out where this one came from...
