Alcohol, also known as booze and hooch, was a type of drink that came in several forms and had mind-altering effects on certain organic species.
Various type of beverages consumed by sentients such as ales, liquors, and wines contained alcohol. Alcoholic drinks could be divided into several categories: wines were made by fermenting fruit or other vegetation with a rising agent, meads were made by fermenting biological sugars, beers were brewed from grains, and liquors were made from various pressed, fermented, and blended ingredients.
Other words for alcohol were "booze" and "hooch".

Excessive alcohol consumption caused temporary intoxication (or "drunkenness"), typically followed by unpleasant physical aftereffects in the form of a hangover. According to Sinjir Rath Velus, Kowakian rum caused the worst cases of hangover, making people "plead for death while hiding in the darkness under [their] bedcovers or even under the bed itself."
One danger of intoxication was impaired judgement: While gambling in the Canto Casino, the alien Dobbu Scay became inebriated and mistook the astromech droid BB-8 for a slot machine. The droid ended up accumulating many of Scay's Cantocoins. During a mission to the Coruscant Underworld, Jedi Ahsoka Tano and Plo Koon went into a cantina to find information on bounty hunter Aurra Sing, due to people being more likely to reveal information while intoxicated.
Drunkenness could also lead to unsteadiness and a staggering gait. This happened to a Quarren member of Gorian Shard's pirate gang as they were drinking with their Trandoshan friend on Nevarro.
Alcohol could also lead to sleepiness: Part of a fake cover story once concocted by Cassian Andor was that his friend Brasso had a bottle of nog at home and they went there and drank themselves to sleep.

Although tolerance for alcohol varied between individuals, it was possible to train one's body to strengthen its resistance.
Alcohol could be addictive: Kylo Ren claimed that Rey's mother and father had sold off their own daughter for drinking money, although it later turned out that they actually sold Rey to protect her from her grandfather, the Sith Lord Darth Sidious.
