Beer is an amazing beverage that's been with humanity for a very long time; it dates back to 9000 BC in Ancient Egypt. Today, it's said to be the third most popular beverage in the world.

There's nothing quite like a cold beer on a hot day. I was known to partake of a beer now and then in a past life; in fact so much so I can't drink it any more. However I do certainly still appreciate the awesomeness of beer for those people who can drink responsibly.

A major environmental challenge of any beverage or food product aside from packaging is transportation - i.e. food miles.

No matter if a beer is made from organic ingredients and bottled in recyclable glass or aluminum containers, it still has to be shifted from point A to point B. Millions of barrels of oil are consumed each year and a huge amounts of greenhouse gas emissions are generated annually just in transporting beer. Until such time that beer trucks are all electric and recharged by solar panels, it's going to be pretty difficult to address this issue on a commercial scale.

It seems such a waste that all those emissions and other associated oil consumption nasties are generated to ship what is essentially just water.

Nearly 20 years ago, I decided to take a crack at brewing my own beer. The environment wasn't on my mind then - the only thing that was, was beer. Cheap beer. Lots of it. Yes please :).

Digging back into my foggy memories of the time, I remember it being quite an easy process; so easy that even a drunk like me could do it.

I bought a barrel, hydrometer, thermometer, bottle caps and a press; plus the ingredients in a readily available kit.  Oh, I also needed bottles which by some strange coincidence were in plentiful supply under the house.

Soon the amber fluid was flowing in large quantities. Generally speaking it takes about 1 week to ferment a brew, depending on temperature. A cold environment will require an external heat sources such as a low wattage thermal pad under the barrel. After fermenting, the beer is left for around a week to mature before bottling. It should then be left 3-4 weeks before drinking.

Not one for doing things in half measures, unfortunately I  decided to see how high an alcohol content I could achieve through the addition of more sugar. I never had it tested, but by jingo it had a kick. Anyway, soon after this I had to cease my home brewing due to rapidly deteriorating physical and mental health, which was shortly followed by homelessness (again). The beer wasn't the problem, just the person consuming it.

My weakness aside, if you do drink beer regularly, think of how much money you could save by brewing your own.

From an environmental aspect, there's practically zero emissions involved in terms of transport, you can also gain more control in what you are consuming as there are many organic beer kits now available. If you've seen how much ready-brewed organic beer is; there's massive savings to be had. You can also use rain water for an even more natural brew.

You can use glass bottles over and over again, saving on resources and energy used in bottle production and recycling. If you only brew during warmer times of the year, you can also avoid having to incorporate an external heat source during fermentation.

There's also just something so satisfying about brewing your own!

These days, you can buy a home microbrewery kit for as little as USD $50, containing everything you need to get started; including step by step instructions. You can find a ton of kits simply by running a search via your favorite search engine on the following terms:

If you really get into home brewing, you don't need to stop at beer - you can also try cider and with some more specialized equipment, wine, port, spirits and other types of liquor.

So, if as a result of reading this you do have a go at home brewing; when test your first batch say cheers to the environment and please also have a beer for me - as unfortunately I won't be able to join you.
