Speaking of canning, I just read that Sam Dams is going to cans. Maybe you've heard. They spent a million bucks developing a new can design that they're going to release to the industry without charge or royalties. Can info at http://blog.samueladams.com/sam-can/
Interesting. I'm cool with cans, but I try to pour my beer into a glass no matter how it was originally packaged.
It does make me wonder if they could have made it more of a pull top, like a soup can. Then you'd basically have an aluminum pint glass.
