Shipping Wine from Italy to US (Cali)

[Innkeeper]

The easiest way is for them to bring it back with them; either in their luggage or in shipping containers usually available at wineries or sometimes at retailers. All the wine should be declared on the customs declaration, and at worst a very small charge will be made. Usually the paperwork is not worth it and they will just be waved through. If they don't declare it, there will be hell to pay.
