It is often claimed that Planter's Punch was created right here in Charleston. The potent concoction of rum, sugar, and citrus was the specialty of the house at the Planters Hotel in the 19th century, and it went on from there to gain national fame. Or so the story goes. Unfortunately, it's not true.
The Planters Hotel was indeed a famous antebellum establishment. It opened in 1809, when Alexander Calder converted the old Dock Street Theatre into a hotel, and it became the favorite resort for rice planters when they came into the city for the winter. The hotel was well known for its imbibing clientèle: a British visitor who stayed there in the 1830s noted that during dinner "very little wine is drank, and rather too much brandy." But there's not a shred of evidence that its bar ever served a beverage called Planter's Punch. That association seems to have been made in recent years based solely on the name of the hotel itself.
See the City Paper for the whole story.
I managed to turn up not just a couple of old Planter's Punch recipes but old recipes in verse!
