Explore the surprising chronicle of the Mojito through the past lives of each ingredient.

There’s this idea that, somehow, tequila and mezcal are healthier to drink because sugar from agave has a lower glycemic index than other sugars. Our medical correspondent Dr. Ryan Aycock, the Cocktail MD, punctures a hole in that idea — and also cautions that, if that idea had been drinking...
