Two stalwart grapes of Spanish white wines are in fact sibling. Verdejo, cultivated in the Rueda region, and Godello, used primarily in Valdeorras and Bierzo, are both derived from the same parent grapes: Savagnin (or Traminer) and Castellaña Blanca.
Verdejo is often considered the Sauvignon Blanc of Spain. This entirely separate grape variety also shares Savagnin as one of its parents and an unknown partner.
