Surely one can buy Albariņo white wine at Trader Joe's or even, maybe, at Sam's Club, no? I remember being shocked to find Manchego Cheese at a Sam's Club in Columbus, Ohio - but didn't buy it because it was VERY expensive for a small piece.
And, while it'll cost you, I know one can ORDER the white wine (as well as Red, Rosado, Sangria, Sherry, Cava, etcetera)through
Tienda.com where they have no less than 4 brands. Surprisingly, at least to me, their cheapest Albariņo at $18.50 (or 13.30) is not far off from the cheapest Albariņo wine here in Madrid. But, of course, through online companies you also pay shipping costs.
