A not too expensive caviar, proscuitto ham, salami, bagel chips, pretzels

cheese and crackers sound fine to me

cheese and crackers, cheese spread and fruit would be great

It’s a rare wine that pairs well with sweets, so forget chocolate and candy canes (except as decoration, maybe?). Most salty foods go nicely with either red or white wines, except for nuts.

Try two or more different kinds of crackers and cheeses, crisp breadsticks, a French baguette (thin loaf of bread), some grapes (red or green seedless), and a DVD of “Sideways” if they don’t have it and are wine lovers.

chilli crisps go well with wine ’

nuts, smoked salmon, fruit, maybe some nice cigars if there into that.

asprin for the hangover

Plate of Cheese varietys maybe some olives and sliced pickles a different kind of Charge!
