Thompson Bros. is back with its mysterious side, because here we have another secret Speyside single malt! Distilled at an undisclosed distillery in Speyside in February 2006, it was then initially matured in a refill hogshead before being transferred to a sherry hogshead for its final 26 months. Eventually it was bottled at 16 years old in May 2022, with a limited release of 277 bottles at 51.1% ABV.
