Wine from California

[Mio]

Dear all,
I maybe did not explain my problem clear enough.This is an assignment (at university)
Of course I can buy wine from California here in Europe too, at a local shop (and ask for help), but my assignment is about how e-shopping is working and the first part of it is to ask for some advice (chat)from an expert what kind of Californian wine I should buy.
Thank you for your co-operation!
Best regards:
Mio
