Special equipment: 32 toothpicks
Cut each peach into 8 wedges. Soak the peach wedges in the wine for at least 1 hour and up to 4 hours.
Remove the peaches from the wine, reserving the wine for another use. Wrap each peach wedge with half a prosciutto slice and fasten with a toothpick. Repeat with the remaining peach wedges and prosciutto.
