Funny! I normally negotiate with the bartender at Vines and let them know that I promise to bring the glass back each night. Since there is no Vines onboard, I just wasn't sure about the wine glasses. You are right about when they know you are serious about your wine. I do get hit up for all the wine tastings and yummy wines do appear for me, as well. Definitely it's worth upgrading to the premier, if one loves quality wine.
