Mezan Diamond Distillery Guyana 2007 PX Cask Finish. I’ve not been reviewing a great deal of Independent Bottlings of late. I’m not going to pretend I’m wearing some kind of halo and advocating Distillery Bottlings. Thing is though, with the likes of Foursquare, Worthy Park and Hampden Estate producing so many of their own bottlings over the past few years, I’ve found my buying habits pointing more in that direction.
