From Vintage Story Wiki
It is noteworthy that alcohol does not spoil, while still providing saturation - therefore turning excess ingredients into alcohol for storage is a valid strategy.
Imbibing alcohol however leads to visual impairment - the player character will swerve their head from left to right, which actually affects movement in the game, since it is hard to walk in a straight line without actively counteracting the movement direction chosen by the swerving head.
The amount and quality of alcohol imbibed influences the severity and duration of impairment.
