This is a young Islay single malt bottled by independent bottler Signatory Vintage from a single cask at natural cask strength. Caol Ila is widely known for a smoky coastal style, and a 9-year-old bottling like this will often show that character in a more direct, energetic way.
Because it is single cask and bottled at 60.1% ABV, this whisky is likely to feel concentrated and robust. The refill butt suggests the cask may have added less overt wood influence, allowing the distillery character to stay at the forefront.
