Place apple cider, cinnamon sticks, nutmeg, and apple wedges in a medium sauce-pan, and bring to a boil over medium-high. Remove from heat, and let stand, uncovered, 20 minutes. Pour cider mixture into a large bowl, and whisk in honey until dissolved. Cover and refrigerate at least 3 hours and up to overnight.
Strain cider mixture into a punch bowl; discard solids. Stir in bourbon and lemon juice. To serve, stir in seltzer and apple slices. Garnish with cinnamon sticks, if desired.
