The opinionated owner of Finca Allende, Miguel Angel de Gregorio, didn\u2019t hesitate when asked recently where his home turf of Rioja, Spain, ranks among Old World wine regions: \u201cRioja belongs in the top five.\u201d\r\n\r\n\u201cThere\u2019s Bordeaux, Burgundy and Alsace in France, Piedmont in Italy and Rioja. But Rioja is a land of 1,000 wines,\u201d he said. \u201cThere is no such thing as typical Rioja, except that it must be made entirely or largely from Tempranillo.\u201d\r\n\r\nIndeed, Tempranillo is the grape that fuels the Rioja Denominaci\u00f3n de Origen Calificada (DOCa), Spain\u2019s most historic and lauded wine region. It accounts for 88% of red grapes, and about three quarters of all grapes grown in the appellation.\r\n\r\nWhile a number of Rioja reds are varietal Tempranillo, many of the region\u2019s showcase wines adhere to traditional recipes and include small percentages of Garnacha (Grenache), Graciano and Mazuelo (Carignan).\r\n\r\nThe French taught Riojano winemakers how to grow better grapes and age wine properly in oak barrels, often for years prior to bottling.\r\n\r\nIt can be light and easy, lush and deep, or elegant and ageworthy, proving de Gregorio right that the region\u2019s Tempranillo-based wines vary in style.\r\n\r\nBut that being said, Rioja doesn\u2019t have a monopoly on the grape within Spain.\r\n\r\nA few hours southwest, Tempranillo is also king in the Duero River Valley that\u2019s home to the Denominaci\u00f3ns de Origen (DOs) of Ribera del Duero and Toro. There, the weather is more extreme than in Rioja, the elevation much higher than it appears, and wines are made entirely from Tempranillo, often referred to locally as Tinto Fino or Tinta de Toro.\r\n\r\nThese wines are generally dark, potent and tannic, sometimes even fierce. To put it in boxing terms, if the best Tempranillos from Rioja are finely tuned middleweights, those from Ribera del Duero and Toro are punch-packing heavyweights.\r\n\r\nAnd that\u2019s the thing\u2014there\u2019s a Tempranillo for every taste. You just need to know where to look.\r\n\r\n\r\nThe Early Bird \r\nTempranillo draws its name from the Spanish word temprano, which means early. While not exactly an early ripener in the global sense, it matures faster on the vine than most other red grape varieties, like the aforementioned Garnacha, Graciano and Mazuelo.\r\n\r\nThe variety particularly excels in the north of Spain, where temperatures are fairly moderate, rivers flow in multiple directions and high elevations help keep the nights cool.\r\n\r\nIn Rioja, for example, the best Tempranillo vineyards are found in the Rioja Alta and Rioja Alavesa subzones, where soils are rich in limestone deposits and generally exceed 1,500 feet above sea level. The Sierra de Cantabria mountain range to the north and Sierra de la Demanda subrange to the south of the Ebro River create an ideal, valley-like atmosphere to cultivate top wine grapes.\r\n\r\nWhile no one knows for sure how long Tempranillo has existed in Spain, the general belief is that the grape\u2019s history in Iberia extends to the time of the Phoenicians.\r\n\r\nWines from Ribera del Duero and Toro are usually muscular and extracted, with the potential for high alcohol and powerful tannins.\r\n\r\nIt was during the 1800s, however, that the variety came to the fore in Rioja. During the worst of Europe\u2019s phylloxera plague, many Bordeaux winemakers crossed the Pyrenees mountains to make wine in Spain, which had not yet been hit by the destructive vine louse.\r\n\r\nThe French taught Riojano winemakers how to grow better grapes and age wine properly in oak barrels, often for years prior to bottling. It was these new techniques that would eventually lead to Rioja\u2019s now-familiar aging-based classifications: Crianza, Reserva and Gran Reserva.\r\n\r\nFrom that watershed era arose wineries including Marqu\u00e9s de Riscal, Marqu\u00e9s de Murrieta, Compa\u00f1\u00eda Vin\u00edcola del Norte de Espa\u00f1a (CVNE), La Rioja Alta, Bodegas Franco-Espa\u00f1olas and Bodegas Riojanas. Today, all make some of the world\u2019s greatest wines.\r\n\r\nThese wines represent a quintessential Rioja style: refined wines of elegance, always based on Tempranillo. They also boast a healthy but integrated mix of spicy berry and plum aromas and flavors, bracing acidity, oak framing and the ability to improve for many years after bottling.\r\n\r\n\r\nBrawn Over Finesse \r\nThe Duero River begins in the province of Soria in north-central Spain. It flows westward into Portugal before it joins with the Atlantic Ocean near the city of Oporto. Along the way, it provides the Ribera del Duero and Toro regions with vital water to nurture Tempranillo.\r\n\r\nWines from these regions are usually muscular and extracted, with the potential for high alcohol and powerful tannins. They\u2019re intense creations with a lot of color, fruit, oak and raw power.\r\n\r\nIn eastern Ribera del Duero, near the town of Aranda del Duero, elevations can exceed 3,000 feet above sea level, while Tempranillo thrives above 2,000 feet in the heart of the region just to the east of Valladolid. In Toro, to the west of Valla\u00addolid, vineyards sit just below that threshold.\r\n\r\nThese heights translate into extreme growing conditions highlighted by long winters and short, hot summers\u2014additional factors that contribute to the final intensity of the wines.\r\n\r\nIf you subscribe to the \u201cgo big or go home\u201d mantra, the wines of Toro and Ribera del Duero are definitely for you.\r\nRecent Tempranillo vintages in Spain\r\n2017: A difficult year. Devastating April frosts in Rioja and the Duero Valley resulted in a massive reduction in yields. A dry, hot summer caused what did survive to be intense and tannic.\r\n\r\n2016: An excellent vintage throughout Spain. Dry, sunny weather through harvest yielded outstanding raw materials.\r\n\r\n2015: Very warm weather in Rioja and the Duero Valley resulted in superripe, fleshy wines. Not a classic vintage for long-term aging.\r\n\r\n2014: Not a disaster, but not great. Rain and cool weather at harvest resulted in uneven ripeness and inconsistent quality across the country. Rot and mildew were also issues.\r\n\r\n2013: Unusually cold and rainy conditions produced austere, acidic wines in both Rioja and the Duero Valley.\r\n\r\n2012: A very good to excellent warm year that resulted in full-bodied wines. Top Rioja Reservas and Gran Reservas are showing well.\r\n\r\n2011: An excellent vintage. Top Rioja Gran Reservas will reward long-term cellaring. Ribera del Duero and Toro wines are more intense than usual.\r\n\r\n2010: A cool, dry, extended growing season resulted in wines with less overt ripeness, higher acidity and unlimited aging potential.\r\n\r\n\r\nSpanish Tempranillos to buy now\r\nCVNE 2011 Imperial Gran Reserva (Rioja); $88, 97 points.
