I am fairly sure that the Rioja would be Faustino. This certainly has "king" style names which go up in quality.

As far as the sherry is concerned in Spain I live in Andalucia where an ice cold fino with sea food tapas is lovely. And of course the solera method of making sherry means that some of that original wine from the original pressing should be in your latest bottle.

Certainly good white wines in Spain are hard to find. But not impossible. Try those from Rias Baixas and Allela I recommended in my first post. Especially the Albarino. (I should have said it rarely if ever comes at a low price by the way). These are from a much cooler and wetter climate.

In fact Spain has more hectares of wine under cultivation than anywhere in the world and the largest grape variety is Airen which makes it probably the most widely planted grape variety in the world - and yet hardly anyone has ever heard of it!! (It's bland tasting and used more in brandy production, though there is at least one varietal made from it).

There is also Txacoli (from the name you might guess this is made in the Basque country, and wine made from macabeo which is one of the cava grapes. I had a bottle of that once, blended with a touch of Pedro Ximenes which was fabulous. Unfortunately I cannot remember the name!!
