Women's Wine Competition names Bianca 2006 of Spain top white wine, but who made it?

The (U.S.) National Women's Wine Competition recently announced the winning wines for 2008. The women-only judging panel gave awards for all wines (even those made by men!) and a special section of awards for wines made by female winemakers.

Taking the top honors for white wine in Women Winemakers Challenge was Bianca 2006 from the Rueda D.O. of Spain. It is made with Verdejo grape. I tried to more information about this wine, but couldn't find too much more. An article from last year in Noticias de Vino which said the the winemaker is named Maria Jose Lopez. I recalled that this is the name of the winemaker for the Riojan winery Bodegas Lopez de Heredia so I contacted them to see if Bianca was a special project of Maria Jose, but, no, this is not the case. Lopez de Heredia works only in Rioja.

So the mystery remains about Bianca 2006, quite possibly the best white wine made by a female winemaker.
