This Bruichladdich 1966 is an original bottling from the early 1980’s, selected by the Italian distributor Moon Import . The name Riserva Veronelli refers to Luigi Veronelli, a highly influential gastronomic writer (mostly for wines but also distilled spirits) and one of the Italian pioneers when it comes to single Maltwhisky.
