Bruichladdich Black Art Edition 11.1 is a 24-year-old Scotch whisky from Islay made using pre-renaissance casks dating back to before the distillery's 2001 reopening. The specific cask types and recipe remain secret, known only to master distiller Adam Hannett. It's bottled at 44.2% ABV and retails for around $550.
This is a lovely dram that grows on you with each successive sip, layering on new complexity but never overwhelms. Tending toward balance, no one flavor pulls too strongly and is unquestionably smooth with a slight spice to let you know its still there.
