I'd say it would depend totally on the nature of the particular dwarf.
Your average dwarf would probably not drink the arcane potion unless absolutely neccesary though, except maybe if he was a close friend with the brewer. Although I can't imagine he'd be too happy about it in that case either.
I didn't know dwarves even used potions made by priests. This is a new bit of knowledge for me. I guess there will be a reason to teach my priest to brew when he gets to a high enough level, lol.
