Bierzo DO

Pliny the Elder and Strabo referred to vineyards in today's Bierzo about 2,000 years ago, and the name derives from the pre-Roman city of Bergidum. The Romans gave a strong push to agriculture here, introducing new crops such as the vine, and the Roman gold workings at Las Médulas are today a World Heritage site. The greatest expansion of the vineyard came with the medieval monasteries, above all the Cistercians, along the busy pilgrim route to the tomb of Saint James; 25 monasteries are documented in the comarca before the desamortización. After centuries of production and some renown in the markets of Galicia and Asturias, phylloxera almost wiped out the vines at the end of the 19th century, causing an economic crisis and even emigration. Production recovered in the first half of the 20th century through grafting onto American vines, and the cooperative movement that arose in the 1960s still plays a very important role. The DO was provisionally recognized on 3 June 1988 and recognized on 11 November 1989, with its Reglamento published in the BOE on 12 December 1989. Work on classifying the vineyards began in January 2015, when the Consejo Regulador's board approved the process, and in 2019 the Ministry of Agriculture ratified the new pliego; the Consejo called Bierzo the first DO in Spain to classify all its vineyards by smaller geographical units. In February 2021 the Consejo Regulador obtained ENAC accreditation to certify wines under the UNE-EN ISO 17065 standard, which it describes as a first among Castilla y León wine DOs.

Bierzo is a single tectonic basin formed in the Alpine orogeny: a ring of rounded, flattened mountains broken by isolated quartzite crests encloses lowlands cut by deep, narrow valleys, and the basin itself is made of Tertiary and Quaternary sediments. The Sierra de los Ancares acts as a natural barrier that calms Atlantic storms, and the landscape divides into a set of small valleys in the mountain zone plus a broad, flat depression, the Bajo Bierzo. Productive vineyards lie between 355 and 1,200 metres, with most of the vineyard area between 400 and 800 metres and vines in every orientation. Soils mix quartzite, sandstone, limestone, clay and slate (pizarra), with a clay-loam texture, an acidic character and no carbonates. Vineyard soils sit on Miocene material under a Quaternary layer and are moderately acidic, with a pH close to 5.5, while hillside soils are made of coarse elements, quartzite and slate. The climate is a mix or transition between oceanic and continental, with a mean annual temperature around 12.3°C, a thermal range around 16°C, average rainfall of 793 mm with October, November and December the wettest months, and more than 300 hours of sun on average in each of July and August. Annual sunshine runs to 2,100 to 2,200 hours.

Mencía is the main red grape of Bierzo: it makes up 75 percent of the old plantings and 70.5 percent of the grapes grown in the production zone. Red Bierzo is typically fresh, structured and persistent, with medium to very high colour and aromas of red and/or black fruit and/or violets, and slow ripening of the grapes gives wines that are very fresh with a subtle acidity. The average vineyard age is around 75 years, with old vines on 85 percent of the vineyard area and plots planted since the late 19th and early 20th centuries. The red field also includes Garnacha Tintorera (1.5 percent of the grapes grown, also known as Alicante Bouschet), Merenzao (between 2 and 3 hectares, known as María Ordoña or Bastardo) and Estaladiña (under 2 hectares, also called Pan y Carne). The amendment approved in 2019 added Merenzao and Estaladiña, and 2020 was the first harvest in which wines of these varieties were made under the DO. Among whites, Godello accounts for 16.7 percent of the grapes grown, Palomino 9 percent, Doña Blanca 2 percent and Malvasía 0.1 percent; white Bierzo may be made from Godello, Doña Blanca, Malvasía and Palomino, and is made principally from Godello and Doña Blanca. At the 2023 harvest, Mencía accounted for 8,259,018 of the 11,681,111 kilos destined for DO Bierzo wines and Godello for 2,530,383 kilos.

• Mencía: 75 percent of the old plantings and 70.5 percent of the grapes grown; 8,259,018 of the 11,681,111 kilos for DO wines in the 2023 harvest
• Average vine age around 75 years, old vines on 85 percent of the vineyard area, and plots planted since the late 19th and early 20th centuries
• Minor reds: Garnacha Tintorera (1.5 percent, also Alicante Bouschet), Merenzao (2 to 3 ha, also María Ordoña or Bastardo) and Estaladiña (under 2 ha, also Pan y Carne); Merenzao and Estaladiña were added in the 2019 amendment

Registered wineries in the DO include Descendientes de J. Palacios, Bodegas y Viñedos Castro Ventosa, Bodegas y Viñedos Raúl Pérez, Bodegas y Viñedos Mengoba, Viñedos y Bodegas Dominio de Tares, Bodegas Estefanía and Verónica Ortega Camacho, among others. In 2019 Álvaro Palacios was responsible for Descendientes de J. Palacios, and Ricardo P. Palacios, also responsible for the winery, sat on the Consejo Regulador's board. In June 2020 Descendientes de J. Palacios was one of the first four wineries to put wines on sale under the new village and paraje labels, alongside Cantariña Vinos de Familia, Silvia Marrao Barreiro (Banzao) and Losada Vinos de Finca. Its wines include Pétalos Mencía (100 percent Mencía, 2021 vintage) and Moncerbal, Corullón (92 percent Mencía and 8 percent Palomino, 2023 vintage). The ancestors of Castro Ventosa's Pérez family were growing vines in Valtuille as early as 1752; the winery sits in Valtuille de Abajo at the foot of the western slope of Castro de la Ventosa, the Roman site that gives the project its name, and it calls itself one of the few Bierzo wineries with all its vineyards in its own ownership. Its Valtuille Cepas Centenarias, first made in 1999, comes from a single plot at Mata los Pardos. Grégory Pérez of Mengoba, Bordeaux-born and a 1998 graduate of the Blanquefort school of oenology and viticulture, worked at Château Grand-Puy-Lacoste and Château Cos d'Estournel between 1997 and 2000; his vines are in Espanillo at the head of the Cúa river, on steep south-facing slopes above 600 metres with soils of clay and decomposed slate. Dominio de Tares has worked Mencía, Godello and Prieto Picudo since 2000 in the DO Bierzo and the Vino de la Tierra de Castilla y León, and made the first vintage of its Cepas Viejas Mencía in 2002. Bodegas Estefanía in Ponferrada makes the Tilenus wines and farms its vineyard organically, and Raúl Pérez is the person responsible for each of them.

• Descendientes de J. Palacios: Álvaro Palacios responsible for the winery and Ricardo P. Palacios a Consejo Regulador board member in 2019; among the first four wineries with village and paraje labels in June 2020
• Castro Ventosa (Valtuille de Abajo): Pérez family vine growers in Valtuille as early as 1752; named for the Roman site of Castro de la Ventosa; Valtuille Cepas Centenarias first made in 1999
• Mengoba: Bordeaux-born Grégory Pérez farms steep slopes above 600 metres at Espanillo, at the head of the Cúa river, on clay and decomposed slate
• Dominio de Tares (working in Bierzo since 2000; Cepas Viejas Mencía first vintage 2002) and Bodegas Estefanía in Ponferrada, whose Tilenus wines are made under Raúl Pérez

A Ministry of Agriculture Order of 11 December 1989 approved the Reglamento of the DO and its Consejo Regulador. Red Bierzo must contain at least 85 percent Mencía, Garnacha Tintorera, Estaladiña and/or Merenzao; rosado needs at least 70 percent red grapes; white is made from Godello, Doña Blanca, Malvasía and Palomino; and the traditional clarete uses 40 to 60 percent red grapes, with 5 to 10 percent destemmed skins added to the fermentation. Maximum yields are 11,000 kilograms per hectare (12,000 for Palomino), irrigation is banned except in the first two years of new plantings, and wines must be bottled within the production area. Red Crianza requires a minimum of two years of ageing with at least six months in oak barrels under 330 litres, Reserva three years with at least twelve months, and Gran Reserva five years with at least eighteen months. The new pliego added optional designations for smaller geographical units: Vino de Villa, Vino de Paraje, Vino de Viña Clasificada and Gran Vino de Viña Clasificada, a top tier the pliego text names Gran Viña Clasificada. Vino de Villa requires 100 percent of grapes from a single named municipality, with yields at least 20 percent below the regional maximum. The named unit may also be a pedanía listed under a municipality, such as Valtuille de Abajo under Villafranca del Bierzo. Vino de Paraje requires 100 percent from a single named site (paraje), with yields at least 25 percent below. Vino de Viña Clasificada requires a single classified vineyard and yields at least 30 percent below; Gran Vino de Viña Clasificada requires the same single-vineyard provenance with yields at least 35 percent below and at least five years of prior use of the Viña Clasificada designation. That vineyard is a single parcel or several adjoining parcels within one mapped paraje, Viña Clasificada also needs at least five years of use of the Vino de Paraje designation, and both tiers must be assessed by the Consejo Regulador before sale. The first village and paraje wines reached the market in June 2020, when the first Viña Clasificada wines were expected in 2025 at the earliest and Gran Viña Clasificada wines in 2030. A resolution of 30 July 2026 gave a favourable decision on a further ordinary amendment to the pliego.

• Core rules: reds at least 85 percent Mencía, Garnacha Tintorera, Estaladiña and/or Merenzao; rosado at least 70 percent red grapes; clarete 40 to 60 percent red grapes; maximum yield 11,000 kg/ha (Palomino 12,000); irrigation banned after the first two years of new plantings
• Ageing: Crianza 2 years with 6 months in oak, Reserva 3 years with 12 months, Gran Reserva 5 years with 18 months, in barrels under 330 litres
• Smaller-unit designations: Vino de Villa (yields 20 percent lower), Vino de Paraje (25 percent), Viña Clasificada (30 percent, after five years as Vino de Paraje), Gran Viña Clasificada (35 percent, after five years as Viña Clasificada)
• First village and paraje wines on sale in June 2020; Viña Clasificada wines were expected from 2025 at the earliest and Gran Viña Clasificada from 2030

Botillo, which the Consejo Regulador calls the most famous Bierzo product, has its own IGP Botillo del Bierzo, alongside the DO Manzana Reineta del Bierzo, the IGP Pimiento Asado del Bierzo and the guarantee marks for Pera Conferencia and Castaña del Bierzo. Las Médulas, a Roman gold working that the Consejo calls the largest open-cast mine of the Roman Empire, has been a World Heritage site since 1997, and the Camino de Santiago crosses Bierzo. In Ponferrada the 12th-century Templar castle rises over the river Sil; other landmarks include the Mozarabic churches of Santiago de Peñalba and Santo Tomás de las Ollas and Villafranca del Bierzo, a Camino stop and historic capital of the comarca. The Consejo Regulador itself is based at C/ Mencía 1, Campo de San Bartolo, in Cacabelos.
