An unusual gift box at the Natural History Museum in London - wine goblets made from beer bottles, where they have just heated and reshaped them, saving a lot of energy in the process. Of course you could use similar glasses for beer, too. I would not go for Corona bottles, though, but which other breweries have nice bottles that could be used? Grolsch comes to mind, and I think I've had a few English barley wines with the label integrated in the bottle, too. Other suggestions?
