I found this link in the news about Micro-Breweries using cans instead of bottles. http://apnews1.iwon.com//article/20110130/D9L2QFUO0.html Correct me if I am wrong, but many of us decant the beer off of the yeast layer when pouring from a bottle. Bottling craft beer in cans, and dumping the cans in a cooler would mix the yeast back into suspension, and also give the beer an aluminum flavor. I guess I would have to give one a try, but it sounds like someone just wants to market more beer at average quality, instead of less beer at higher quality.
