The Alambic's aged gin stuff is pretty great. I have the one barrel-aged for 11 years, then finished for another 2 years in Carribbean rum casks. Barrel strength (131.2 proof). Tastes very herbal actually. Like a mix of gin, Chartreuse and a bit of rum. The ones aged in scotch-casks (Ardbeg/Port Ellen etc.) are supposed to be great too.
