Bairrada: Baga Reds and Traditional Method Sparkling

Bairrada is a Denominacao de Origem (DO) in Portugal's Centro region, administered by the Comissao Vitivinicola da Bairrada (CVB). CVB states it was created on June 27, 1986 as a non-profit, private-law interprofessional association, and that it acts across an area covering the DO Bairrada, the IG Beira Atlantico and the Terras de Sico sub-region. CVB counts 138 associate members among cooperative cellars, producers, bottlers and grape growers, and describes its role as certifying wines, overseeing viticultural technique and winemaking process, and promoting the region's products. CVB's own account of the region notes that its wines and sparkling wines carry a longstanding reputation, and that the region is Portugal's oldest and most important for sparkling wine, producing sparkling wine since 1890, many of them by the classic method. IVV's registered caderno de especificacoes for the DO records the legal basis for the designation in Portaria n.o 212/2014, of October 14, and Decreto-Lei n.o 61/2020, of August 18, and lists the Conselho Geral of the CVB as the applicant entity and IVV as the intermediary and competent control authority.

• CVB was created June 27, 1986 as a private-law, non-profit interprofessional association (CVB)
• 138 associate members: cooperative cellars, producers, bottlers and growers (CVB)
• CVB describes Bairrada as Portugal's oldest and most important sparkling wine region, producing sparkling wine since 1890, many by the classic method
• DO Bairrada's legal basis: Portaria n.o 212/2014 of October 14, and Decreto-Lei n.o 61/2020 of August 18 (IVV)

IVV's caderno de especificacoes delimits the DO Bairrada geographic area to the north by the Vouga river, to the south by the Mondego river, to the east by the Bussaco and Caramulo mountain ranges, and to the west by the Atlantic Ocean. The area covers the municipalities of Anadia, Mealhada and Oliveira do Bairro in full, plus named parishes of Agueda, Aveiro, Cantanhede, Coimbra and Vagos. IVV describes the terrain as mostly flat plain or plateau with gentle hills, generally not exceeding 250 metres above sea level, always close to the Atlantic, which IVV states markedly influences the region's climate. IVV classifies the climate as Mediterranean with strong Atlantic influence, with long, cool winters carrying abundant rain, and warm summers moderated by Atlantic winds, with days warm and nights cool and a significant thermal range. CVB separately describes the climate as temperate with strong Atlantic Ocean influence, cool, long, rainy winters, and summers softened by west and northwest winds, with a thermal amplitude during grape ripening that CVB says can reach 20 degrees Celsius, helping preserve fruit acidity. On soils, IVV records mineral soils of different geological eras, ranging from sandy to clayey with some sandy loam, with vines grown predominantly on clay and clay-limestone soils; IVV traces the vine-growing soils to sedimentary rock, concentrated on Jurassic limestone, Triassic sandstone or Cretaceous conglomerate outcrops. CVB adds that the clay-limestone soil found across the region varies in proportion locally, carries a good amount of silt, and is loose, porous and greyish in colour.

• Geographic area bounded by the Vouga river (north), Mondego river (south), Bussaco/Caramulo ranges (east) and the Atlantic Ocean (west) (IVV)
• Terrain mostly flat plain or plateau, generally under 250 metres above sea level (IVV)
• Climate: Mediterranean with strong Atlantic influence, long cool rainy winters and warm summers moderated by Atlantic winds (IVV)
• Vines grown predominantly on clay and clay-limestone soils, over Jurassic limestone, Triassic sandstone or Cretaceous conglomerate (IVV)
• CVB records a thermal amplitude during ripening that can reach 20 degrees Celsius, helping preserve acidity

Bairrada is registered as a Denominacao de Origem Protegida (DOP), using the traditional national terms Denominacao de Origem (DO) or Denominacao de Origem Controlada (DOC), per IVV's caderno de especificacoes. The specification covers three product categories: Vinho (still wine), Vinho Espumante de Qualidade (quality sparkling wine) and Vinho Licoroso (liqueur wine). Minimum actual alcoholic strength is 11% vol. for white, red and rose wine and for quality sparkling wine, and 16% vol. for liqueur wine; minimum natural strength of the must is 11% vol. for still wine, 9.5% vol. for quality sparkling wine and 12% vol. for liqueur wine. Quality sparkling wine with the right to the DO must be produced by classic-method bottle fermentation (metodo classico) and must remain at the producer's premises for at least 9 months after bottling before it can be sold, per IVV. Liqueur wine is made from must of grapes fit for DO Bairrada, in the early stages of fermentation, fortified with wine spirit of 52% to under 86% vol. Maximum yields per hectare are 100 hl for white and rose wine, 80 hl for red wine, 120 hl for quality sparkling wine and 100 hl for liqueur wine. Vines must be trained in cordon or a semi-free form, at a planting density above 3,000 plants per hectare, on brown or red limestone soils, non-humic or humic lithosols, or podzols of loosely consolidated sandy material, per IVV. A 'Classico' designation is also defined: red wine must age at least 30 months, 12 of them in bottle, and white wine at least 12 months, 6 of them in bottle, from a restricted list of the DO's authorised varieties, at a lower maximum yield of 55 hl/ha and higher minimum alcohol (12% vol. white, 12.5% vol. red).

• Registered as DOP; national traditional terms are DO and DOC (IVV)
• Three categories: Vinho, Vinho Espumante de Qualidade, Vinho Licoroso (IVV)
• Quality sparkling wine: classic-method bottle fermentation, minimum 9 months at the producer's premises after bottling before sale (IVV)
• Maximum yields: 100 hl/ha white/rose, 80 hl/ha red, 120 hl/ha quality sparkling, 100 hl/ha liqueur wine (IVV)
• 'Classico' red wines age at least 30 months (12 in bottle); 'Classico' whites at least 12 months (6 in bottle) (IVV)

IVV's caderno de especificacoes lists the varieties authorised for DO Bairrada wines: the red (tinta) varieties Alfrocheiro, Aragonez, Baga, Bastardo, Cabernet Sauvignon, Camarate, Castelao, Jaen, Merlot, Petit Verdot, Pinot Noir, Rufete, Syrah, Tinta Barroca, Tinto Cao, Touriga Franca and Touriga Nacional; and the white (branca) varieties Arinto, Bical, Cercial, Chardonnay, Fernao-Pires, Pinot Blanc, Rabo-de-Ovelha, Sauvignon, Sercialinho, Verdelho and Viognier. CVB, on its region page, calls Baga the region's 'casta tinta rainha' (queen red variety) and states that, grown on the region's clay soils, Baga produces wines loaded with colour, very rich in tannins and of high longevity. A restricted list applies to wines labelled 'Classico': the whites Arinto, Bical, Cercial, Fernao-Pires and Rabo-de-Ovelha, and the reds Alfrocheiro, Baga, Camarate, Castelao, Jaen and Touriga Nacional, per IVV. Decanter's profile of the Baga variety, drawing on the group of producers called Baga Friends (Pato & Wouters, Quinta das Bageiras, Luis Pato Wines, Niepoort, Sidonio de Sousa, Quinta da Vacarica and, at publication, the newest member, Vadio), describes Baga as thin-skinned, vigorous and late-ripening, and quotes Decanter contributor Sarah Ahmed calling Luis Pato 'the father of modern Baga.' Decanter also reports that Bairrada's clay soils, well-drained and light-reflective, help ripen Baga's fruit and balance its acid and tannin.

• Authorised red varieties include Baga, Touriga Nacional, Castelao, Aragonez, Merlot and Cabernet Sauvignon (IVV)
• Authorised white varieties include Arinto, Bical, Fernao-Pires, Chardonnay, Sauvignon and Viognier (IVV)
• CVB calls Baga the region's 'casta tinta rainha' (queen red variety), noting deep colour, high tannin and longevity on clay soils
• Decanter: producer group Baga Friends includes Pato & Wouters, Quinta das Bageiras, Luis Pato Wines, Niepoort, Sidonio de Sousa, Quinta da Vacarica and Vadio
• Decanter quotes writer Sarah Ahmed describing Luis Pato as 'the father of modern Baga'
