209083 Rioja           Discovered 2003 Sept. 17 by F. Hormuth at the Starkenburg Observatory, Heppenheim.
Rioja is a wine made from grapes grown in the autonomous community of La Rioja and in parts of Navarre and the Basque province of Álava. The most widely-used grape is the richly flavored Tempranillo. The discoverer remembers this wine well from occasional otherwise cheerless cloudy Spanish observing nights.
