Juice is the substance from fruits taken by Drake, in order to feed the captains on their voyage. One bottle of juice will be consumed at every nightfall, no matter how many crew members are on board. At the beginning of the game you are given 3 juice bottles to start your voyage. Different fruits provide different amounts of juice, the lowest possible being half a cup, the maximum being 3, and the average being 1.51. Juice will come in different colors depending on what fruit is used, though the different colors have no special properties. A total number of 97 juice bottles can be found in a single playthrough, excluding the 3 you are given at the beginning.
