Planning notes for a Halloween party

Specialty cocktails with spooky names are a must - batch them ahead.
Dark spirits (whiskey, dark rum) fit the theme better than clear spirits.
Punch bowls with dry ice create amazing effects.

Halloween parties are cocktail-heavy. The table above sizes the spirits, and batching one or two specialty cocktails is the easiest way to serve them. Red wine fits the theme well. Have themed cups and garnishes.
