I've always loved the bottle design for Isklar, ever since I first saw them working in Waitrose. Blue Marlin is the guilty party and I like a few of their other brand designs too. Like what they've done for Kettle Chips:
They speak about how the brand was becoming over-run by new products entering the luxury crisp market so it needed a small re-vamp and de-clutter of the packaging. They've done it perfectly in my view.
