Water in the Worm

4 min

Copperhead Glen's owners discovered last Friday that Cask 14-G, a 12-year single malt reserved for a premium release, filled bottles at only 43% ABV instead of the certified 58%. Lab analysis confirmed the cask had been topped up with water sometime during the previous fortnight. Fergus Malt, the head stillman, is the only staff member with an unsupervised key to the barrel warehouse and the bottling line. He insists the low reading is a calibration error on the refractometer and denies any tampering. The question before you is whether Fergus Malt deliberately diluted Cask 14-G.
