Old Monk Rum (750 ML) is $20.99 at CBC Liquors, Westford in Massachusetts — in stock now, with pickup and local delivery. Made since 1954, Old Monk rum is India's favorite rum. Despite sharply declining sales in recent years, the brand sold nearly four million cases in 2014. While the rum carries an age statement of seven years, it should be placed firmly in the category of "dark rum" due to the addition of molasses and other flavoring agents.
