Bodegas Muga is located in Haro, in Spain’s Rioja region. The estate was founded in 1932 by Isaac Muga Martinez. He died in 1969 but his children still run the estate, which includes 690 acres of vineyards. In addition, Bodegas Muga leases nearly 400 nearby acres from other owners. Vineyards are planted to Tempranillo, Garnacha, Mazuelo (Carignan), and Graciano for red wines. White wines are made with Viura and Malvasia. The flagship wines are Tempranillo blends, and they impress wine writers. Robert M. Parker Jr. generally rates the reds in the mid- to high-90s, and notes that “Muga is the only winery left in Spain that uses only oak throughout the entire vinification process. They have their own cooperage and import the oak directly from the U.S. and France.”
Rioja Demoninación de Origine Calificada is Spain’s most important wine region. Located in northern Spain, it comprises 135,000 vineyard acres and was the first official appellation in Spain, earning its official DO status in 1926. In 1991 it became Spain’s first DOCa, Spain’s most prestigious appellation category. The DOCa is divided into three subzones: La Rioja Alavesa in the northeast; La Rioja Alta in the southwest; and La Rioja Baja in the east. About 75 percent of Rioja wines are reds, with Tempranillo the predominant grape. Garnacha (Grenache), Mazuelo (Carignan) and Graciano, a spicy, high-acidity red grape, are also allowed. White wines are made from Macabeo, Garnacha Blanca and Malvasia. Wines were made in this region well before the Romans arrived, though the Romans then the medieval monks refined vineyard management and wine production. In the 19th century French families migrated to Rioja after phylloxera wiped out their vineyards, and the French helped establish the tradition of wine blends, still part of Rioja winemaking. According to the rules for the appellation, a wine labelled a simple Rioja can spend less than a year in an oak aging barrel. A Criziana is aged for at least two years, one in oak. Rioja Reserva is aged at least three years, with at least one in oak. A Rioja Gran Reserva must be aged at least five years, with two years in oak.
