The Greenest Beverage? Tap water. But What About Adult Beverages?

In a quest for discovering the most environmentally benign beverage for back yard bar-b-ques, one builder sifted through the options to help us drink greener.

I have nothing against water: I make coffee with it, paddle a canoe in it, and I even drink it every day. But it's not always what my empty hand is looking for when I settle down in the back yard and fire up the bar-b-que. Beer sort of hits the spot at these times. To determing whether I should be drinking cold beer in a can or cold beer in a bottle, I called my local recycling coordinator who wasted no time in telling me that tap water was my best choice.

Tap water wasn't what I was after, so I refined my query
Listening to NPR on the way home from work one day I heard that recycling 30 beer cans saved the equivalent of a gallon of gas. How many beer bottles, I wondered, would be equivalent to 30 beer cans. So I asked my local recycling coordinator He did some research and we ran the numbers. It turns out that 385 beer bottles has the equivalent embodied energy of 30 beer cans. He pointed out that there was some minimal adjustment needed to account for the transportation cost of imported beer so this calculation would be most accurate if applied to domestic beer in both bottles and cans. Ah-ha! I said, this gives me an environmental rationalization for buying that nice local microbrew!

Does this mean I get to "invest" in a kegerator?
Actually he replied, the kegorator idea is a no-go due to the carbon footprint of the refrigerator (regardless of the impact of the increased beer consumption). However, if you consider that there are 22 shots of bourbon in a bottle that likely has the embodied energy content of two beer bottles this gives you an environmental justification for drinking bourbon on the rocks (or mint juleps). If a single beer can equals 12.83 beer bottles it is roughly equivalent to six bottles of bourbon in terms of its carbon footprint.

As a dedicated environmentalist I find his logic irrefutable.
