The best known of all Partagas is the Serie D No. 4, the robusto size that formed part of the legendary Partagas alphabet series that dates back to the 1930's. In 2005 a Piramide, the Partagas Serie P No. 2, was added to the range, which fast became a cigar of choice amongst lovers of full flavoured Habanos. In 2011 the Serie D No. 5 and the heavy ring gauge Serie E No. 2 extended the alphabet series once again.
