Cachaca 51 is the best-selling brand of cachaca in Brazil, the home of this unique sugarcane-based spirit. That may not sound like a big deal, but according to the producer, they sell 240 million liters of the stuff annually, which makes it the second-biggest-selling spirits brand in the world. (Independent research does not seem to bear this out, but that’s largely irrelevant to our cause here — which is how it actually tastes.)
Cachaca 51 has the traditional fuel-like pungency of cachaca up front, but it’s folded in with some interesting notes of lime zest and lemongrass, tempering the petrol overtones considerably. The body is a bit sweeter than most cachacas, offering notes of light brown sugar, spearmint, and more citrus fruits — lime, especially — on the back end.
