False. There is so many types of beer that are made both in bottles and cans regardless of the quality of the beer. For example "Brewhouse", not high quality beer whatsoever but comes in cans and bottles, as well as almost every middle of the road beer (Budweiser, Coors, Kokanee, etc etc)
Also if you buy bottles vs cans of the same beer. It is actually cheaper to buy bottles due to the less amount of beer you get...
but anyways, as people were saying plastic sucks
