Why I’m Causing Global Warming By Brewing Beer

Alright, so plants turn CO2 into oxygen, and forestall global warming. And I’m causing it by making beer.

To see why, let’s look at step 1: the mash/boil process. In mashing and boiling, I’m burning propane in order to heat the water (and then the wort) in order to make the beer.

Burning Propane:
C3H8 + 5 02 -> 3 CO2 + 4 H20 + heat

So by burning propane, I’m creating CO2 (greenhouse gas) and water vapor (also greenhouse gas). So I’m creating global warming right there. Not to mention the direct heat created by burning.

But it gets even worse. Plants turn CO2 into oxygen, and thus forestall global warming. Well, what is malt? Malt is barley seeds, allowed to germinate before being roasted and then malted to become sugar. Hops are flowers. So I’m killing plants (in the case of malt, baby plants), and thus taking them out of the photosynthesis cycle and stopping them from reducing atmospheric CO2.

Think that’s bad? I’m just getting started! Now we have fermentation!

C6H12O6 -> 2 C2H5OH + 2 CO2 + 2 ATP

See that? The yeast turns sugar into alcohol, more CO2, and more heat.

And if I haven’t done enough, I throw that beer into a keg, and go through tanks of pressurized CO2 to carbonate and serve it. I go through a 5 lb CO2 tank every few months.

And I’m not even purchasing carbon offsets. Aren’t I just naughty?

  1. I think the plant death and fermentation, like respiration, only cycle the carbon already in the ecosystem to no long-run net harm. You only really cause problems by burning propane and reintroducing carbon which was for millenia trapped in the earth’s crust into the ecosystem.
