One way to restore stamina and Dead-eye in Red Dead Redemption 2 is to drink coffee. This feature is initially unavailable. On this page we explain how to unlock coffee brewing in RDR2.
Two main ingredients are needed to brew coffee in the game. The first one is Ground Coffee. You can buy it in the shop (by default for 1 dollar) or find it easily while exploring the game world.
The second ingredient is more important. It is a Coffee Percolator. You can buy it e.g. in a multi-branch shop in the town of Valentine. By default it costs 7 dollars and 50 cents.
Having acquired all the ingredients, find a campfire, e.g. in your main camp. Now you can hold the button to pour yourself some coffee.
