wedding tables, wine bottles opened or no?!
Opened, for convenience, not aeration.
I'm a sommelier.
you could buy the kind with the screw top so that they remain closed but are easier to open by guests. If not, i would say keep the sealed, having a bottle sitting open would be weird, and if they don't drink it then there's just an opened bottle sitting there all night. Also, it could spill. Mostly, I think I would just feel weird if the bottle was sitting on the table open. Leave a corkscrew somewhere for them to use
Opened unless u have waiters to open them ..u don't want some old relative to make a fool of themselves when thay fumble around and drop the bottle ...also some say good wines need to breath before serving so if u have the $ get wine decanters
