Potion of booze
From Wikihack
A non-blessed potion of booze will make you confused for 3d8 turns. It will also provide some nutrition and abuse your wisdom. If the potion is cursed, it will make you pass out for up to 15 turns. If the potion is not diluted, it will also heal 1hp. A blessed potion of booze will not cause confusion.[1]
Potions of booze are sometimes used in conjunction with the Scroll of gold detection on the Elemental planes to detect magical portals, but note that this is only useful with uncursed potions, since the desired effect is confusion.
Samurai will see this as a potion of sake.[2]
Dipping an amethyst into a potion of booze will turn the potion into a potion of fruit juice.[3]
Some players take an ice box filled with potions of booze when ascending, in preparation for the Demigod bar.
