Edicion Limitado has been aged for 5 yrs.
Double ligero is from what I understand, comes from the sixth priming at the top of the plant, known to be the strongest or most robust. It is a very thick and hearty leaf. Usually requires more aging. The DL 600, DL 700 and Chisels obviously are made up of this part of the plant.
The Ligero comes from the second or third priming of the plant. More standard. Flavorful but not anything close to the DL. On the La Flor's the DL has a darker wrapper than the Ligero's.
Hopes this helps.
