Beiroa is a wool yarn composed exclusively of wool of the Bordaleira da Serra da Estrela breed from animals registered in the respective herd book. Beiroa softens and blooms beautifully after washing! This 100% non-superwash Portuguese wool yarn is manufactured in Portugal for Retrosaria exclusively from the wool of free grazing Bordaleira Serra da Estrela sheep. 

Retrosaria Rosa Pomar makes minimally processed heritage wool yarns from Portugal. Their yarns are created in collaboration with small manufacturers, breeders associations, and shepherds. All Rosa Pomar yarns are non-superwash, not bleached, have no silicone-based softeners, and mulesing is not practiced in Portugal.
