El Tarasco Añejo, Mexico - Mexico isn't known for its rums (take for example Dead Head). This one, and its sister rum (below) are actually pretty decent. Very smooth, it gently caresses your palate. Sweet, but not overpowering. Cheap, but it doesn't come across as such.
El Tarasco Plata, Mexico - fruity and coconutty. Definitely a good cocktail rum.
