Here's a new one on me: red Txakoli. Was somewhat similar to zweigelt. Maker is Talai Berri, according to their Web site they're the only ones who make a red. 100% Hondarribi Beltza.
I was actually @ this vineyard in October. It's a nice light wine, that would go well w/a strong fish (blue fish?). That said, you still can't beat a white Takoli from Getaria.
My wife and I loved txacoli wines. It's our favourite white wine and we have such a hard time finding it in Asia. Hope you enjoy it!
