Ya know, I just had my teeth cleaned by the dentist after being way overdue for a checkup. I had some BAD red wine stains on my teeth.
My hygienist told me that I should drink my red through a straw. I said no way.
Apparently, though, it's more common that one thought; pros who need amazing white teeth all the time really DO drink all stainy bevs--including red wine--through a straw.
