Drew Estate's Liga Privada Único Serie (aka Unico Series) originally debuted in 2010 with the launch of the fan-favorite Liga Privada Dirty Rat cigar. This limited release featured similar tobaccos used in Drew Estate's regular-production Liga Privada cigars (Liga Privada No. 9 and Liga Privada T52), though the tobacco proportions and leaf primings featured a higher degree of sorting/specificity, with the overall recipe being custom tailored to accentuate the 5" x 44 corona format of the Dirty Rat.

This is the mentality for the Liga Privada Único Serie, with each and every cigar in the collection being built from the ground up, best showcasing the size at hand. Over the years, the collection has grown to include upwards of 11 cigars, with each being unique in their own right. The common trait that runs through the collection is a rich smoking character, showcasing the very best tobaccos, blending, and quality construction from Drew Estate.
