Check this new stuff out: Peter’s Planters Punch.
Wait, what is planter’s punch? It is a traditional rum punch made with fruit juices, grenadine, curacao, and bitters. That is a lot of stuff to lug out to the beach, so Steve Shaw Jr. and his company SDS Enterprises have created a pre-mixed version that sells for around $4 a bottle. Right now it is only available in Florida, but the Internet savvy can probably procure a bottle.
