Foursquare Cask Strength 12 yo has been a revelation for me. I tried the 2005 in a Zoom tasting and was spell-bound. Amazing complexity and utterly mesmerizing. It is from Barbados, matured in first fill ex-bourbon, not chill filtered, natural colour and about 60% ABV. Not easy to find either. Managed to pick up the 2008 which I cracked open 25/12 and this too is a very special bottle. Cannot recommend Foursquare highly enough except it does not need any additional demand so it is fortunate not many read The Spirits Forum.
