I have found a sealed 750ml flagon of Usquaebach. It is a beige bottle in a red velvet box. The printing on the bottle says "Over 170 years of tradition"
Imported by Twelve Stone Flagons Ltd.
Blended & Bottled by Douglas Laing & Co. Ltd

Would appreciate any information before I open this at the next poker game.

It was found in my parents liquor cabinet.

Thanks,
Steven
