Ok, so wine etiquette/hostess etiquette states that the wine you bring to the party is not to be opened at the party.
I know, this seems silly, but unless you want Martha Stewart breathing down your neck, don’t get cranky if the hostess doesn’t open your wine, because she’s following etiquette rules.
I don’t think you can make that generalization at all. Not all women like fu fu drinks with umbrellas on top. A good scotch is an evolved taste (says the scotch & bourbon snob), and it has NOTHING to do with your gender.
