An interesting event for our Californian friends will take place at the Castro Point Restaurant, in Mountain View, from 5:00 pm to 10:00 pm:

Bring any Malbec from any Malbec producing wine regions from around the world and the corkage fee will be waived.  This can be Cahors, Bergerac, Mendoza, Maipu or any other new Malbec producing wine regions.

More detail.

A thrilling array of "black wines" from Cahors made their way to Paris for a
tasting at the wine-specialized restaurant Le Taste Monde. In a sleek, wood-paneled setting past the dining room, long tables held spit-buckets, napkins and twenty-five different examples of wine made from the Malbec grape.
