I have Princess Grapevine winelists from the last few times that I attended a wine tasting. The Pouilly-Fume, Loire Valley, is the same #52 on all of them - no label.

Winelists from various Princess ships can be found at www.cruiseclues.com

CC contributor LARGIN knows a lot about Princess wines and may know the name of the wine you're inquiring about. Maybe he'll see this thread and be able to help

Cheers!
Chris
