Some folks from the Homebrewchatter.com, a forum dedicated to homebrewers, recently discussed the use of used commercial aluminum beer bottles to fill with their own home brewed beers!
Personally I think it’s a great idea. I know other people have made fuel tanks and even stoves out of used aluminum bottles. It just demonstrates the durability of these bottles and their “green” advantages.
I’d be extra careful about labeling the re-used aluminum bottles though. You could end up taking a swig of gasoline rather than than beer 🙂
