Although it might be preferable to vodka.

I mistakenly assumed silver didn't tarnish ( like gold ) but it does - with sulphur and moisture of all things, so does copper.

My Talisker (pewter) seems fine for 2 or 3 days.
But my favourite is a flask, rather large I admit, that came with Cognac in it and when finished, I kept it for whisky. Yes it's at least twice the size of a proper hip flask, but it's glass, with a plastic-lined cap that seals perfectly and comes in a soft kid leather pouch. No effect on the whisky at all.
