Bairrada: Baga Reds and Traditional Method Sparkling

Bairrada is a Denominacao de Origem (DO) in Portugal's Centro region, whose wines are certified by the Comissao Vitivinicola da Bairrada (CVB). The CVB was created on June 27, 1986 as a non-profit, private-law interprofessional association, and it acts across an area covering the DO Bairrada, the IG Beira Atlantico and the Terras de Sico sub-region. Its 138 associate members include cooperative cellars, producers, bottlers and grape growers. Its role is to certify the wines under its jurisdiction, oversee viticultural technique and winemaking process, and promote and publicise the region's products, and it also issues guarantee seals for approved wines. The reputation of Bairrada's wines and the recognition of their quality were already established in the nineteenth century, when the region's potential for sparkling wine was recognised, and in 1890 Bairrada produced Portugal's first commercially significant sparkling wine. The CVB calls Bairrada the country's oldest and most important sparkling wine region, producing sparkling wine from 1890 to the present day, many of them by the classic method. The DO's legal basis is Portaria n.o 212/2014, of October 14, and Decreto-Lei n.o 61/2020, of August 18. The Conselho Geral of the CVB is the applicant entity, and the Instituto da Vinha e do Vinho (IVV) is the intermediary and the competent control authority.

The DO Bairrada geographic area is bounded 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. It covers the municipalities of Anadia, Mealhada and Oliveira do Bairro in full, plus named parishes of Agueda, Aveiro, Cantanhede, Coimbra and Vagos. The terrain is mostly flat plain or plateau with gentle hills, generally not exceeding 250 metres above sea level, and always close to the Atlantic, which markedly influences the region's climate. The climate is Mediterranean with strong Atlantic influence, with long, cool winters of mild average temperatures and abundant rain, and warm summers moderated by Atlantic winds, bringing warm days, cool nights and a significant thermal range. Summer heat is softened by winds from the west and northwest. During grape ripening the thermal amplitude can reach 20 degrees Celsius, which helps preserve the fruit's acidity and gives the wines freshness. The soils are mineral, from different geological eras, mostly poor and ranging from sandy to clayey, with some sandy loam, and vines are grown predominantly on clay and clay-limestone soils. These soils derive from sedimentary rock, and vine-growing is concentrated on Jurassic limestone, Triassic sandstone or Cretaceous conglomerate outcrops. The clay-limestone soil found across the region varies in proportion from place to place, 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)
• Terrain mostly flat plain or plateau, generally under 250 metres above sea level
• Climate: Mediterranean with strong Atlantic influence, long cool rainy winters and warm summers moderated by Atlantic winds
• Vines grown predominantly on clay and clay-limestone soils, over Jurassic limestone, Triassic sandstone or Cretaceous conglomerate
• Thermal amplitude during ripening 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). 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. 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. 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
• Three categories: Vinho, Vinho Espumante de Qualidade, Vinho Licoroso
• Quality sparkling wine: classic-method bottle fermentation, minimum 9 months at the producer's premises after bottling before sale
• Maximum yields: 100 hl/ha white/rose, 80 hl/ha red, 120 hl/ha quality sparkling, 100 hl/ha liqueur wine
• 'Classico' red wines age at least 30 months (12 in bottle); 'Classico' whites at least 12 months (6 in bottle)

Authorised red (tinta) varieties for DO Bairrada wines include 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; authorised white (branca) varieties include Arinto, Bical, Cercial, Chardonnay, Fernao-Pires, Pinot Blanc, Rabo-de-Ovelha, Sauvignon, Sercialinho, Verdelho and Viognier. The CVB calls Baga the region's 'casta tinta rainha' (queen red variety), and 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. Baga is thin-skinned, vigorous and late-ripening. Bairrada's chalky clay soils, well-drained and light-reflective, help ripen Baga's fruit and balance its acid and tannin. Baga Friends, a group of leading exponents of the variety, includes Pato & Wouters, Quinta das Bageiras, Luis Pato Wines, Niepoort, Sidonio de Sousa and Quinta da Vacarica, with Vadio's Luis Patrao its newest recruit as of August 2022. Writing in Decanter, Sarah Ahmed calls Luis Pato 'the father of modern Baga.'
