Info on a specific wine

[Aviator]

In an attempt to surprise my girlfriend for Valentine's Day, I'm wanting to order a bottle of a wine she told me she really likes. She said it was "Chateau St. Michael," but I've never heard of it and have not been able to find anything about it via a Google search. She said it's not a wine that the usual wine stores carry. Has anyone heard of it? Or perhaps I've missed it a little bit and someone's heard of something similar? Thanks!
