Thus far in the Ask the Expert series, we’ve taken a look at several categories that people are confused about. For instance, brandy vs. cognac, and mezcal vs. tequila. Another hiccup arises here, with cachaça vs. rum. What’s the difference between the two, and how are they related?
Interest in cachaça soared last year during the Rio Olympics, with everyone clamoring about the spirit, gulping down caipirinhas, and generally blundering by calling the stuff “Brazilian rum.” While that’s not totally inaccurate, it passes along the misconception that cachaça somehow followed in the footsteps of Caribbean-based rums, or was made in imitation of them.
To the contrary, cachaça is thought to predate rum’s birth in the Caribbean—it began there on Barbados, likely in the mid 1600s—by at least a few decades, if not more. Putting aside the who came first debate then, is cachaça still essentially the same thing as rum?
