For extreme camping, canned beer is preferred due to the weight savings and crushability of the cans after consumption.
Canned and bottled beer have the same quantity, but a can of beer seems to disappear after just three or four gulps, whereas bottled beer lasts longer. I have never figured out why. I feel like I sip (gulp) both about the same.
Also a good thing, a lot of vodka now comes in plastic bottles. Glass is too fragile to drag around while camping at Burning Man.
