Mojitos contain club soda, too although caiprinhas do not and the multiculti Brazilians recoginize the legitimacy of the vodka-based caipiroska. Para agorrorar la borrachera, esta bien cualquier vino. Making mojitos requires a bit of know-how, one has to "muddle" together the mint, rum, and sugar to get the right flavor. Sounds like the bartenders were greenhorns.
