As with all recipes, you need a tool. For Black Coffee you need a Kettle.
To make a Cup of Coffee, you only need one component: Coffee Bean. This item however, is (currently) only available as a plant on the countryside outside Sao Paolo, Mexico City and Singapore (to be harvested with Advanced Botany and a knife).
A Cup of Coffee only has a 3 hour lifespan. Drink it freshly brewed! Also, you can only drink a cup of coffee every 6 hours. However, it has five charges, so you can pass it around with a few of your friends, perhaps as a pre gig caffeine boost! Coffee has a very very small positive effect on your mood, which goes away after 30 minutes.
Coffee Beans come with 10 charges, so each “Coffee Bean item” lasts for 10 cups of coffee, each of which can be used by 5 people (but only during it's 3 hour lifespan).
