Cask no. w0911200019b. Generously shared by my neighbor who is from Yuanshan. It's love at first taste as intense sweet raisin curant and plum mingle up on your tongue. The 54% cask strength is deceptive there is no burn whatsoever. definitely out of my price range at US prices but my neighbor assured me you can get it at a fraction of the price back and Taiwan. I hope he hits back to visit soon so I can have him pick up a bottle.
