Monymusk Overproof White Rum. Monymusk Sugar Estate lies in the South of the island of Jamaica on the Vere Palins in the parish of Clarendon. Rum has been made from Jamaican molasses in this area since the 18th century. Monymusk rum is initially distilled at the ultra modern Clarendon Distillery. The rums in the Monymusk portfolio are then blended and aged at the nearby Innswood facility which was also formerly a distillery but is now a blending and ageing house.
