If you want to really know what a good maduro ought to taste like, try one of the Padron 1964 or 1926 maduros a try. Then for a lower cost alternative, try the Tatuaje Reservas, I'd probably recommend starting with the 7th Reserva. Also give Crowned Heads Jericho Hill or La Imperiosa a try.

Ignore the CAO or 5 Vegas, or really any CI house brand.
