One of the few rums (NB: French spelling rhums) in the world to claim a terroir as the sugar cane is grown in a unique microclimate in volcanic soil on the slope of Mt Pelee on a sloping field with low cloud ceiling and sea breezes, (most sugarcane is grown on flat land on poor soil) on a single estate making it a unique microclimate and small circumscribed geographic area – much like the great houses of Bordeaux, Cognac or Champagne claim weather, soil and geographic demarcations and resulting effects. Another noteworthy point is that it is a Rhum Agricole or made directly from sugar cane juice rather than molasses. Less than 5% of the worlds production of rum is made this way and the process yields a dramatically different product. It is one of a series of rums (which differ in age) the others being Rhum Blanc J.M., Rhum J.M. Paille (Gold),and Rhum J.M Millesime 1997. This particular version is aged in American and French Limuosin Oak casks for at least 4-5 years before bottling.
