It's green to drink beer that comes in standard bottles. The industry standard beer bottle (ISB) is reused around 15-20 times, (depending who you ask) and that's much more efficient than being smashed up, melted & re-formed into new bottles - as happens when bottles are recycled.
Reduce. Reuse. Recycle. - Reuse comes before recycle.
A lot of the the craft beer and micro-brewery beers that are so popular at the moment - particularly among the hippie crowd seem to come in large - funky lookin' non-standard bottles that aren't as easily reused, and so are less environmentally friendly. That bothers me - hippies are supposed to like green choices.
Vote with your dollars - buy your beer in standard bottles.
