How to Drink Truly “Green” Beer on St. Patrick’s Day

How to Drink Truly “Green” Beer on St. Patrick’s Day

Your St. Paddy’s Day beer may be tinted an amusing and pretty shade of green this week, but have you ever considered how eco-friendly and sustainable your beloved brewskies really are? If you want to ensure you’re maintaining your environmentalist credentials while hoisting a few brews, keep these considerations in mind:

Keg, Can or Bottle?

The keg is king. Besides being handy for large gatherings, rented beer kegs are reused about twice a month or 22 times a year. Kegs are durable enough to last two decades. Using them means that about 58,000 fewer beer cans and bottles get tossed into the trash every year.

Even in a restaurant or bar, beer on tap from a keg is almost always the more eco-friendly choice than from an individual bottle or can. This is true even after taking into account the need to truck the beer from brewery to bar, as well as the need to wash the glasses.

The Bottle vs. The Can

If your choices are limited to bottled or canned beer, your instinct might be to choose a bottle. They can be washed and reused, so they seem to be the greener choice, right? Not so fast. This is a subject of some debate.

“Generally speaking, every time you drink a can of beer and you recycle it, some part of that can will be back up in a shop within the next 60 days,” Kim Marotta, MillerCoors’ director of social sustainability, told “The other part that’s interesting is that if you make a can out of recycled content, it requires 95% less energy.”

Fans of the bottle, however, say that if you consider a container’s entire life cycle and the manner in which it is made, bottles clearly win. In part, this is because most of the bauxite required to manufacture aluminum cans comes from environmentally damaging mining operations in Jamaica, Guinea and Australia.

“Recycling 100 beer bottles requires more energy than recycling 100 aluminum cans, but making the aluminum cans requires a lot more energy,” David Allaway, a solid waste policy analyst at Oregon Department of Environmental Quality, told

No clear winner here, then, which is why drinking locally produced beer winds up a greener choice than either bottles or cans.

Think Globally, Drink Locally

If your goal is reducing the carbon footprint of the beer you drink, choose locally brewed beverages. Many craft brewers now source their hops and grain locally, reducing the pollution that inevitably results from shipping beer ingredients across the country or around the globe.

Look for craft brewers who go the extra mile to respect the environment in ways like these:

  • Using heat from the brewing process to heat office space and other structures
  • Using spent grain as a co-fuel for beer production, which can reduce energy consumption by as much as 70 percent a year
  • Using organically grown ingredients
  • Using wastewater creatively, infusing it with microorganisms that turn it into gaseous fuels like methane or hydrogen
  • Using water efficiently, such as harvesting rainwater and minimizing evaporation
  • Preventing spent sediment, yeast, proteins and grains from ending up in landfills by sending them to special processing facilities instead
  • Using wind or solar energy to power production

Now that you have the facts, get out there and enjoy a few eco-friendly beers. Remember to drink responsibly, designate a driver and minimize your impact on Mother Nature.

To be sure, make your own. In the United States it is legal to brew your own beer without a license as long as you don't sell it, same with making wine. That way you will know what is in it and where it comes from.

Not a big beer drinker but thanks for the information.

my beer-drinking pals say that draft is the way to get the best taste. Bottles in my town are not reused, aluminum cans are recycled.

I like to drink beer. In summer, many Chinese people sitting together, drinking beer, chatting with each other. The freetime made everyone comfortable and satisfied....An old song named "Summer Wine" is just in the condition.You can go into the bar and share the wine-time with your friend. Of course, don't forget your shoes in the end!
Summer Wine:
Strawberries, cherries and an angel kissing spring
My summer wine is really made from all these things

I walked in town on silver spurs that jingled to
A song that I had only sang to just a few
She saw my silver spurs and said let's pass some time
And I will give to you...summer wine
Oh..oh..oh...summer wine
Strawberries, cherries and an angel kissing spring
My summer wine is really made from all these things
Take off your silver spurs and help me pass the time
And I will give to you...summer wine
Oh...summer wine

My eyes grew heavy and my lips they could not speak
I tried to get up but I couldn't find my feet
She reassured me with the unfamiliar line
And then she gave to me...more summer wine
Woh..woh..oh...summer wine
Strawberries, cherries and an angel kissing spring
My summer wine is really made from all these things
Take off your silver spurs and help me pass the time
And I will give to you...summer wine
Mm...summer wine

When I woke up, the sun was shining in my eyes
My silver spurs were gone, my head felt twice its size
She took my silver spurs, a dollar and a dime
And left me craving

I don't drink beer.
