Up to your DM if this is an alternative to finding drinks...
If you have anything I should add tell me
Just wanted to add that any beverage has loopholes to create +3 Vorpal Butterknives
Would Sovereign glue count as a beverage i mean its an adhesive but hey you could glue your mouth or neck shut so you cant breath or talk or um eat.
Hey, it's definitely drinkable. Not very safe but Drinkable. So yes, mix it with some lime juice, put it in a glass, and add a little umbrella and straw and it could be a beverage.
what about endlis poisen?
If it's a liquid then yes. Not that a DM would allow it.
