What do you mean by 'react'? There's no chemical reaction between the vapor and the ss, just some condensation, and that occurs with any material that vapor contacts. It's a simple question of whether you can detect any taste from the steel, and whether it bothers you enough to try an alternative or not. As vtac points out, there is a way to eliminate the metal, but for most people the minuses of doing so outweigh the pluses.
That's more like Obama mode to me- half and half
