I don't understand Mojitos. The Mojito basically a shot of clear, cheapo rum, such as Bacardi mixed with muddled mint, sugar and lime and then watered down with club soda.
It's a bastardized version of the refreshingly delicious Caipirinha, http://www.eventosnatura.com/IMAGENES/catering/Caipirinha_coctail.jpg which contains Brazilian Cachaça with no mint and club soda. The Caipirinha is the national drink of Brazil whereas the Mojito, most likely spawned by Spring Breakers, was invented in Miami. Cachaça, also known as Firewater, is distilled from sugar cane whereas rum is distilled from Molasses. It has a more tropical flavor with less of that harsh sweetness.
The next time you're at a bar and you want a Mojito, ask for a Caipirinha. They can be flavored with other fresh fruits such as pineapple, berries, etc. if desired, but most enjoy them au naturale.
