- "You had your bottle filled with milk! Drink up for health and long life with (C). One drink recovers five hearts. With this special offer, you'll get two helpings in one bottle!"
- — In-game description
Milk is one of the main products of Romani Ranch, along with its improved version, Chateau Romani. It must be stored in a bottle. One bottle contains two helpings, each of which restores five hearts. It will also remove the jinx placed on Link when he is hit by a Blue Bubble. Milk is especially useful early in the game, when Link has so few hearts that two helpings can restore more total health than a Red or Blue Potion.
Milk can be purchased from the Milk Bar in East Clock Town at night if Link has acquired Romani's Mask, which he is rewarded with for protecting Cremia and her carriage of milk from the Gorman Brothers. Milk can also be received as a gift from cows when "Epona's Song" is played for them. The Gorman Brothers sell Milk at their ranch, but it appears to be watered down, overpriced, and stolen from Romani Ranch. Ironically, the Gorman Brothers claim that the milk from Romani Ranch is watered down and overpriced compared to what they sell. Romani will give Link a new bottle full of Milk if he defends the ranch from Them.
In the Nintendo 3DS remake, there is a Mystery Milk that acts as a curative to overdosing on Chateau Romani, in which Link must deliver for Gorman. This milk spoils in two minutes, becoming "Moldy Milk".
Milk returns as a bottled item that restores health upon consumption. A bottle of milk contains two servings, each restoring three hearts. Link is given a half-empty bottle of milk after he brings Sera's cat back to her. This is the second item that Link obtains in the game, after the Fishing Rod. After that, Link can purchase Milk at any time from her shop, or at the shop on Death Mountain. Early in the game, when Link has few hearts, Milk's two servings will restore more total health than a Red or Blue Potion. Also, Link can use each Milk serving after taking minor damage, restoring his health to full so that he can use the Great Spin Attack more often.
There are no Cows seen in Hyrule during Twilight Princess, but there are goats in both Ordon Ranch and Hyrule Castle Town, meaning the milk featured in this game is likely to be goat milk and not cow milk. To further this theory, only Ordon Goat Cheese, a goat milk product, appears in this game. It is of course entirely possible that cows were simply not added to the game.
Milk can be purchased at the Milk Bar in Kakariko Village for 20 Rupees. Unlike its previous appearances, milk now only has one serving, and restores five hearts when consumed.
