Here's the recipe they sent me:
16 oz. Pineapple juice
16 oz. Fresh Orange juice
2.5 oz. Natural Syrup
3 oz. Red Grenadine
16 oz. water
Make a batch without the Natural Syrup (I am assuming that is Simple Syrup used at bars) because I found it too sweet with the syrup.
To make it easy, you might want to try the pineapple/orange juice from Dole. I find this drink is really refreshing and because it isn't too sweet, it quenches your thirst!
Enjoy!
