I love this playful take on the sake glass by TALE, a Seoul, South Korea who are doing some really fantastic work. Simply called a Moon Glass, the unique shape of the cup mimics the phases of the moon as you drink the sake. You start with the a full moon, and as you drink the moon begins to wane, just like the sake. It’s a clever idea that’s also unexpected, especially if you were to be handed a glass unknowingly. The sad part is that I don’t think the glass is for sale, or at least I can’t find anywhere with that info.
You should also check out there Matterhorn Glass, which has to be one of the best glasses ever to drink whiskey out of, especially if it were to be heavily chilled first.
