Alfred Lamb's 1939 Special Reservation Rum
Alfred Lamb's Special Reserve was distilled in Jamaica in 1939 and aged in a puncheon, a larger cask than the normal hogshead. It is believed these were bottled in the late 80s or early 90s.
The exact distillery of origin remains unclear but consensus seems to be that this is "Pure Single Pot" - meaning Hampden is a strong contender.
A limited edition of 918 bottles.
