La Rioja Alta, S.A.

La Rioja Alta was founded in 1890, when five Riojan and Basque families created the Sociedad Vinícola de La Rioja Alta in Haro's Station District. The first president was a woman, Doña Saturnina García Cid y Gárate, and the first winemaker was the Frenchman Monsieur Vigier, whose first wine, the Reserva 1890, was the predecessor of today's Gran Reserva 890. In 1904 Don Alfredo Ardanza, a founder of La Rioja Alta and owner of the Ardanza Winery, proposed merging the two companies; the Reserva 1904 made to commemorate the event eventually became the Gran Reserva 904. The company took its definitive name, La Rioja Alta, S.A., in 1941, and on 28 September 1942 it registered the Viña Ardanza brand. The Viña Arana brand was introduced in 1974, replacing the classic 6º Año, and in 1978 the house registered Viña Alberdi, which replaced the old Tercer Año (Third Year). The first vintage of the Club de Cosecheros, the winery's customer club, came in 1976. The company celebrated its centennial in 1990 and in 1996 built a new cellar in the municipality of Labastida. In 2023 the Gran Reserva 904 brand released its first Selección Especial. The founding families' descendants remain the principal shareholders and directors of the winery.

The group owns more than 800 hectares of its own vineyards. Tempranillo is the main variety, alongside Graciano, Mazuelo, and Garnacha. Production is limited to under 5,000 kilos per hectare. Tempranillo comes from estate vineyards in Briñas, Labastida, Villalba, and Rodezno, Graciano from the Montecillo vineyard in Fuenmayor, and the Tempranillo in Viña Ardanza from the Cuesta vineyard in Cenicero and from Montecillo. The Garnacha for Viña Ardanza comes from La Pedriza in Tudelilla, Rioja Oriental, a 40-hectare estate whose vines were planted in 1999. Viña Alberdi draws on the Mayorita, Las Monjas, El Palo, and El Bardal vineyards in Rodezno and Alto del Rey in Labastida, at 500 to 600 metres on clay-limestone soils. The company has allocated 16 hectares of vineyards to 100% organic viticulture and has installed a solar farm in Labastida. It has also acquired 35 hectares of old vines, with a minimum age of 45 years, in the village of Elvillar in Rioja Alavesa.

The house combines tradition (making its own barrels, racking by candlelight, and long ageing) with modern winemaking technology. Its coopers make every barrel from wood imported from the United States and dried in the open air for two years at the Haro facilities. Every barrel is racked by candlelight, a practice that removes sediment naturally and allows each barrel to be monitored individually. An optical grape selection system was implemented in 2015, and the grapes pass through optical sorting tables. In 1981 the 890 was aged for seven years in American oak; by 2020 it spent six, and its rackings had been reduced from 12 to 10.
