Don't trust what you read on an anonymous forum, please do some digging elsewhere on your own for an authoritative answer in writing. The rules for working crew members are different than for passengers. On my way back from a recent trip the other FO was bringing back two bottles of liquor. When he mentioned it the CA warned him that he was only allowed to bring back one, and if he got caught at Customs he'd lose his Global Entry. So I bought the extra one off him. Full crews arriving into SFO lately have been getting searched. I have no idea what the rules are regarding wine. I'd start looking around the ICE website and if you don't find anything try a PDR. And if you find a solid answer... post it here!
