This is an 11-year-old single malt bottled by independent bottler Decadent Drams from Dutch distillery Millstone. It was drawn from a single first-fill Pedro Ximenez sherry hogshead and released at cask strength, giving it a fuller, more concentrated style.
For a novice drinker, that cask information suggests a whisky likely shaped by rich sherry influence, with deeper sweetness and oak than a lighter refill cask might show. The natural bottling strength of 51.1% ABV may make it feel bold and intense, so a small splash of water can help open it up.
