Coffee is a feature in Wild World and subsequent games. It is available from The Roost in Wild World and City Folk, and the Cafe in New Leaf. It is also available as a held item in New Leaf after three coffees have been ordered.
When a player becomes a regular visitor, Brewster will offer "pigeon milk" which lightens the color of the coffee. Coffee can be bought in other towns from City Folk onwards, whereas this option is not available in Wild World.
In New Leaf, the coffee item can be held like a tool. The player sips from the coffee after pressing A, finishing the drink after five sips.
In all games coffee has appeared in, it is shown that villagers and some other characters also drink coffee. In New Leaf, several different villagers from the town and other towns that the player has visited may stop by the Cafe to buy coffee, as will other characters such as Tom Nook, Tortimer, and Pelly.
Each character has their own coffee preferences. This information is important when a daily job opens up after six coffees allowing the player to serve coffee to visiting characters.
- 'Pigeon milk', or 'crop milk' is a substance that is produced by all pigeons and doves, as well as some flamingos. Crop milk is produced in the 'crop', which is where birds store food temporarily; it is almost nothing like mammalian milk.
- As pigeon milk is fed to young pigeons, it's likely this signifies that Brewster has parental feelings toward the player.
- In City Folk and New Leaf, on Valentine's Day, coffee changes into hot chocolate, and Brewster is a little more open to the player.
- In a conversation with an uchi villager, they may ask Brewster during the winter, "Hey, Brewster, that winter blend you were working on... What did you end up naming it?" Brewster will either respond with "...Winter Coffee.", "...Winter Storm.", or remain silent with "..." a similar event happens in the summer where the uchi villager asks the same thing and Brewster will either respond with "...Summer Coffee", "...Summer Storm" or stay silent with "..."
- In a conversation with a snooty villager, they occasionally mock Brewster by saying the Roost should serve breakfast or sweet snacks, which Brewster responds with "But... I only know how to make coffee..."
