Monymusk (also called Clarendon) distillery is an active rum distillery built in 1949 in Lionel Town in the south of Jamaica. The distillery produces circa 12 million litres of pure alcohol per year of which 9 million litres are made with its column still and 3 million litres with its pot stills. The production facility is composed of two buildings. The oldest one holds two double-retort pot stills of 20,000 litres (5,300 gallons) and 25,000 litres (6,600 gallons) connected to their respective fermentation oak tanks and producing a spirit of about 85% ABV. The most recent facility built in 2009 accommodates a triple column still producing a spirit lighter in aromatic compounds up to 96% ABV.

Monymusk offers two different styles of pot still rums : light and heavy. Both rums styles are made from molasses, a mix of sugarcane juice, bagasse (among others sugar cane fibres left post pressing). The main difference lies in the fermentation time which is fairly short for the light style – 2 to 3 days- and much longer for the heavier style – 2 to 4 weeks-. Multiple marks/marques exist defining exact production specification, a bit like a cuisine recipe.
