Castellana

The Story

Castellana Blanca is one of the great unsung heroes of Spanish viticulture — a "founding variety" first documented in 1513 that quietly became the genetic ancestor of two of Spain's most celebrated white grapes: Verdejo and Godello. DNA research has confirmed that Verdejo (the star of Rueda DO) is actually the offspring of Castellana Blanca crossed with Savagnin (Traminer from France's Jura). And Godello — the darling of Bierzo — shares the same ancestry. Without Castellana Blanca, there is no Rueda. Once grown throughout virtually every Spanish wine region, phylloxera and the 20th-century obsession with international varieties nearly wiped it off the map. Today, meaningful surviving populations exist mainly in the Canary Islands, where old-vine specimens escaped the plague entirely on volcanic soils. A small renaissance is quietly underway in Castilla y León, where heritage-minded researchers and growers are recovering pre-phylloxera material. It was officially listed among Spain's 40 "ghost varieties" — present before phylloxera, then practically vanished. For now, Castellana Blanca remains an insider's grape: the kind that wine geeks quietly hunt and academics study. Its moment may be coming.

Insider Story

The alias confusion is part of Castellana's story. It travels under multiple names across Spain — Pardina, Jaén Blanco, and various local synonyms — which has made it hard to track, count, and protect. Spanish wine geneticist José Vouillamoz (co-author of Wine Grapes with Jancis Robinson) was instrumental in clarifying Castellana Blanca's role as a progenitor variety, but many Spanish vignerons still don't know they're farming an ancestor of Verdejo. In the Canary Islands, where the Atlantic climate and volcanic terroir have preserved dozens of pre-phylloxera varieties in living memory, Castellana survives as an authorized variety in several DOP blends. The real insider play: as Spain's "rediscovery of native varieties" movement accelerates (the country recently identified 210 previously uncatalogued varieties), Castellana Blanca is positioned as a prestige heritage marker — the vine that started it all.

Technical Deep Dive

Castellana Blanca (Vitis vinifera) is genetically identified as a parent of both Verdejo and Godello via DNA microsatellite analysis. The cross: Castellana Blanca x Savagnin = Verdejo (and by extension, Godello shares this lineage). Viticulturally, it is an early-documented variety (first record 1513) that was once widespread across the Iberian peninsula. It is highly susceptible to phylloxera and was thus devastated in the late 19th century, surviving primarily in ungrafted old-vine plots on the Canary Islands' volcanic soils where phylloxera cannot survive. As a white variety it is medium-vigour, producing wines with moderate to good acidity, clean fruit character, and natural alcohol in the 12-13% range. It is not currently an authorized variety in most major mainland Spanish DOs, though recovery efforts in Castilla y León aim to change this. In the Canary Islands it appears as an authorized component in certain multi-variety white wine blends.

Industry Secrets

Spain's "ghost variety" revival is the sleeper trend of the 2020s. Projects like the Castilla-La Mancha rebirth of ancient varieties and the Canary Islands' old-vine preservation movement are quietly documenting pre-phylloxera material. Castellana Blanca is on the radar of Spain's top ampelographers as one of the most genetically significant unprotected varieties in the country. The fact that it's the parent of Verdejo — Spain's #1 white wine grape by volume — yet remains almost commercially invisible is a unique story gap. The first winemaker to bottle a quality Castellana Blanca varietal wine from old Canary Islands vines will own a remarkable narrative: "the wine that preceded Verdejo."
