You definitely can come up with something nice that sounds plausible. To give you some ideas though, there are some varieties on the drink with mild (or less mild) psychedelic effects, generally by either getting specific mushrooms into the mix, or through additives of spider venom. There's also a version that due to a particular blend of ingredients is rather non-uniform in it's alcohol content. You could pour a bottle out in a number of identical glasses, but some would be as potent as a light beer, while others would kick like heavily distilled drinks.
