A good one from Spain

Had this last Thurs with some co-workers:

Castano 2003 Solanera Vinas Viejas ($11, WC) - Monstrell (Mouvedre?) 65% and Cabernet Sauvignon 35%. Soft, med-big, lush with fruit and spices on the palate. Very drinkable. Don't remember the aroma. [A-]

Retried this last week as Costco had it for $10 a bottle. The second bottle was OK with some of the rich softness of the first bottle [B-], but the third bottle was quite disappointing, with a muchmore brittle texture and a rougher taste [C]. Bought another bottle (hidden under some others at CC ) and retried this again 10/16/2006 and this bottle was much bettter [B+].
