Rhum Agricole or French style rum, originated in the French Caribbean Islands and is made directly from fresh-pressed sugarcane juice. The difference between this and the rum we are familiar with (known as Demerara Rum) is its production - Demerara Rum is produced from molasses (a by-product of the sugarcane refining process). The two different styles result in quite diverse products. Rum tends to be sweeter, smoother and rounder, whereas Rhum Agricole is often much drier and appreciated as having a bolder, sharper taste.
Its production is strictly controlled by the French government, it's made from one ingredient, from locally grown sugarcane that's cut, ground, and pressed into fresh juice. Over two to three days, this liquid ferments before being distilled and rested in stainless steel or aged in wooden barrels.
Darker rhum is typically enjoyed neat. While blanc rhum is best used in cocktail recipes.
