Have you called the Lamberts on the telephone?
I just went to Yahoo! People Search and typed in Rick Lambert in Lindale, TX. I found two phone numbers. You might want to try giving them a call, or try again, if you already have.
If that fails, go to Lindale, TX and knock on their door. You could ask them for a tour of their winery; that would get them to warm up to you. :-)
Someone else is going to have to be of assistance. My plate is pretty full with the Paul v Clinton battle.
