The major difference between cachaça and rum is that rum is usually made from molasses, a by-product from refineries that boil the cane juice to extract as much sugar crystal as possible, while cachaça is made from fresh sugarcane juice that is fermented and distilled.[15] As some rums—in particular the rhum agricole of the French Caribbean—are also made by this process, cachaça is also known as Brazilian rum.[8]
