Testing which potion we got by such and such stirring pattern would be fun.
You give it to your hero and he is instantly dead. Or you give it to some criminal sentenced to death/Azkaban and he becomes unkillable for a month, or invisible to Dementors :)
Or you give it to rat and nothing happens—you try to kill the rat and he’s killed—maybe that was potion that makes you invisible to dementors?

That sounds a lot like modern drug testing, actually...
