Stir hot water and honey together in a cocktail shaker until the honey dissolves.
Add sage; muddle with a muddler or the handle of a wooden spoon until the leaves are slightly bruised and fragrant, about 30 seconds.
Add cherry juice and lime juice.
Fill the shaker with ice; cover and shake until the outside frosts and the drink is chilled, about 15 seconds.
Strain into 2 ice-filled rocks glasses; top with sparkling water.
Garnish with sage leaves and/or lime wedges, if desired.
