Potions are useful consumable items represented by the '!' character. Every potion has a specific effect (beneficial or harmful!) when quaffed. You can't drink potions while berserk, in bat form, wisp form, tree form, fungus form, or lich form, or if you're a mummy.
Apart from using a scroll of identify, there are several ways to determine the identity of potions you've picked up.
Some race/class combinations begin with potions identified. All characters recognize potions of blood, fighters start with a potion of might, and wanderers may start with some identified potions in their inventory. Wanderers also have a chance to recognize potions of curing regardless of inventory.
Quaffing a random potion is the most obvious way to figure out its contents, but may be dangerous. You'll want to be somewhere safe with no monsters in sight, in case of a potion of ambrosia, potion of lignification, or potion of berserk rage. Potions of degeneration and potions of mutation are also harmful, but those effects do not wear off by simply passing turns.
Monsters sometimes drink potions within your line of sight. This identifies the potion.
You may also guess at a potion's identity by the size of the stacks in your inventory. Potions of curing are the most frequent (about 25% of all potions generated), followed by potions of heal wounds (about 13% of all potions generated). This is very unreliable if your highest potion stack is only 2 or 3 since potions are sometimes generated in batches. On the other hand, potions of beneficial mutation, cure mutation, and experience are very rare (less than 1% of all generated potions), so you're unlikely to pick one of those if you only drink potions when you have two of the same type.
Some more notes on potion identification:
- If you find an altar of Cheibriados surrounded by 2 potions and 2 fruits, these potions are either potions of lignification or potions of haste.
- A certain entry vault for the Orcish Mines has multiple potions scattered about in addition to several placed behind a door. All of these are bad potions (such as poison or degeneration).

0.17 removed potion of decay and potion of restore abilities. It also made any potion able to be found in a stack, so that information can no longer be used to narrow down the possibilities. Monster quaffing always identifies a potion.
As of 0.14, the basic 40 satiation for all potions was removed, and the potion of slowing was replaced with the potion of lignification. Potions of speed are known as Potions of haste. Known potions that would have no effect can no longer be quaffed.
Prior to 0.13, instead of potions of beneficial mutation, there were the potions of gain stat, which gave (as a mutation) increases to individual stats.
Prior to 0.12, you could throw potions to generate cloud attacks against enemies with the Evaporate spell. You could also identify several unpleasant potions by creating samples of them through Fulsome Distillation.
