Bordeaux

[Andrew]

We have formed a neighborhood wine tasting group of completely novice wine drinkers. It is my turn to host. The host picks the wine type and each guest brings a bottle of that type. The catch is that it must cost less than $20 per bottle. We then do a blind taste test. My question is: If I ask them to bring a bordeaux, would that have to come from France? Could bordeaux come from California or Australia?
