Screw tops can be very un-romantic in table-side presentation.
Sorry, Kerry, I don't agree with that. Unless the server is an absolute klutz at his/her job.
I see nothing romantic about opening a bottle of wine under cork and having it foully tainting and reeking of mold at tableside.
I also see nothing un-romantic about a pristine bottle of fine wine sitting on or by table with an efficient closure method visibly protecting the wine.
This past week I had dinner at one of the most expensive, highly rated, and truly elegant restaurants in the SF Bay/Wine Country region. Dinner bill for four came to not much under $1000. Food, decor and service was equisite. The first bottle we had (after a glass of champagne and some caviar) was a Grosset Riesling Clare Valley. It was just as elegant, and just as elegantly delivered to our glasses, as the next two wines which were cork finished. Actually, I thought it the best wine of the evening; and Grosset lacks elegance not at all.
