Have You Met My Friend Txakoli Yet?

Let me present my new favorite wine. Txakoli! Not only is it delicious, it's fun to say. (It's pronounced something like CHA-kol-ee.) Txakoli is white. It's sparkling. You pour it from up high. And it's Basque. I predict it will be the new hot thing. That assumes it's not already the new hot thing because, well, I have been living under a rock these last few months. I've found a couple of blogs that have written about the delights of Txakoli already--not too many, which suggests that the tipping point has not yet been reached...

Have you seen Txacoli in London? If so, where? And when? And did you drink it?
