The only Peruvian cigar company I know is Tabacalera del Oriente:

Their San Martin is supposed to be pretty good. I don't have any experience with it. Most Peruvian tobacco I've seen is blended with other (better quality?) tobacco and used as filler--I'm thinking of sticks like La Aurora 1495 & CAO Italia.
Everything is worth trying once!
