I don't know about Senorita, but I know there's a seller on eBay who is from Thailand and they've got Veinte Cohol, they ship to the US with a Cert, so I'd assume they could ship to Europe too? But I'm not fully sure. They're not cheap but if you have no other source, they're the way to go.
Here's an example listing -

Although now that I've read it, looks like they do ship worldwide, but Euro customers can't get the Cert.
