The scene where Peter Vincent hands the "regular tap water" as holy water to Jerry Dandridge to drink in order to prove to Charley that Dandridge is not a vampire.
Dandridge seems to have a moment of hesitation and doubt just before he drinks it: "And are you sure that this is, um,(gulp) holy water?"
After Peter Vincent says ambiguously that he saw "Father Scanlon bless it down by St. Mary's", Dandridge blatantly (via Director Tom Holland) holds the holy water down in front of the flames of the fireplace. Why does he do this?
In folklore or witchcraft is it supposed to neutralize any blessings? I mean it's not cognac!
I'm pretty sure director, Tom Holland, was trying to show the movie audience something by the close up of the holy water being place by the fire for a few seconds. But what?
I always thought that he held it up to the fire to get a good look at it, to tell if it was really holy water or tap water. He was promised on the telephone that it would only be tap water; he was double checking. His vampire-ness let him see if it had been blessed just as it would have burned and blistered him once opened and touched (had it been real).
I always thought that Jerry did that to make the water warm or heat it up slightly. Since he likes blood, and that's typically warm, maybe he likes his water warm too? Or, maybe he was trying to inspect it to make sure that it was only tap water.

I'm not sure why this is being queried, it's very obvious in the scene. Dandridge isn't 100% sure it's not all a double bluff and that it's not real holy water. He's merely holding it to the light of the fire for a better look - because as a vampire he can see a hint of whether it is or not? Because he's doing it to see if he can unnerve them into betraying their true intention? - we don't know either way ultimately, but he's sceptical as to whether Vincent is a dumb stooge or intent on harming him after all. The fire though is just for better light to see it by.
People are very dumb sometimes and that's why they miss even the very obvious. Hence this whole discussion. It doesn't make the truth less obvious because people aren't paying attention. It's still there.
This is a stretch, but when I saw the scene I got the feeling Dandridge was going to throw the phial in the fireplace (the way some toasts are done after gulping wine) but Roddy gave him a look as if to say, "don't do that, I need it back". Just a silly bit of comic relief. Whatever was intended, it was an odd, memorable scene.
I was thinking the same thing HapHazzard was--why is anyone confused over this scene at all? I agree with everything he said and I've also always thought this was obvious. Guess not though. :P
In vampire lore, holy water was known to glow when a vampire was nearby OR just in general holy water was supposed to send off a glow. My assumption is that Jerry was holding it up to the fire to see if it was glowing.
I must say, the_eradikateor is the ONLY person who answered the OP's question with what seemed to be some knowledge of vampires/holy water/fire. I'm not that into researching vampires and their powers, but _erad sure made sense and actually mentioned a possible reason why he held it to the fire.
As for HapHazzard....holy *beep* dude. Your arrogance is hilarious. The ONLY actual reason you gave, after questioning the OPs "query", (and then calling people dumb in a later comment) was....."the fire though was just a better light to see it by." Do you even realize this? Probably not. You sound too fuqcing arrogant.
Tom Holland mentions this in at least one of the "pirate commentaries." He sort of says that Jerry has some "vampire power" that allows him to see if the water is blessed. Maybe? Holland was not very clear on exactly what that bit meant.
Mr. Vincent used regular tap water. Dandridge was holding it up to the light to make sure. With his vampire power he was able to see whether or not it was blessed by holding it up to the light.
