Aranda de Duero is a Spanish town and municipality in the south of the province of Burgos. It has a population of roughly 32,000 people. The post code for the town is 09400. The closest airport is in Valladolid. Aranda de Duero is the capital of the Ribera del Duero wine region. The town is unique for having wine cellars that interconnect below the streets of the town centre. Wine clubs (peñas) celebrate special events in these cellars. Aranda de Duero is at the junction of several transport routes across Spain. The N1 autovia (or A1 as it's now known) runs north / south by Aranda, along which visitors and import/export goods travel between Madrid and the south coast. Another important road running east to west connects Portugal with important cities on the way (eg Zamora, Valladolid, Soria) and the east coast. Its situation at the juncture of these routes has lead to Aranda de Duero acquiring a growing recognition and function as a business centre. Several multinational corporations, such as Michelin and Glaxo Smith Kline have large facilities in the area. A dish called Lechazo is a local speciality. This is roast baby lamb and is usually served with a basic salad and lots of "torta" bread for dipping in the meat juices.
