Checking the Decanter web site, I just came across this well-written article (from 2yrs ago) on the various white wine offerings from Spain. I have noticed that Spain is gaining more shelf space in my area and certain stores have a very good selection (not just your average plonk!). I know there are quite a few Espana fans here so read on when you have the time.
