Enjoy a magic item I designed for D&D 5e:
Mimir, the talking flask of endless alcohol
Flask of Endless Alcohol
Wondrous item, rare (attunement is optional)
This silver hip flask appears to contain half a pint of some nondescript alcoholic beverage. A creature can use an action to drink up to half a pint of the drink. After resealing the flask, it can refill with more of the same beverage.
As an action, you can pour at least half a pint of any nonmagical alcoholic beverage into the flask and reseal it. Afterwards, the flask can start refilling with more of that same beverage whenever resealed.
