Beer-a Culpa: Traditional Lambic Brewing How-To

Meredith Melnick — Tue, 08 Jul 2008 06:58:36 +0000

What was a “look, cool: wild yeast-fermented beer!” afterthought to my post on sustainable brewing has met an indignant commenter crowd who found my two-sentence description rightfully vague and careless. And so, as penance suggested by commenter koelschip, here is a complete guide to making lambic beer. Whether you are an old Belgian couple who ferments outside or a homebrewing web user with closed wild yeast inoculations in your basement, I think we can all agree that sour beer is delicious. And the greenness isn’t so bad either: reclaimed oak barrels, energy-free inoculation and all natural ingredients (provided you don’t start with the sham fruit syrups and packaged yeast…) contribute to its carbon-reduced diet.

Step #1: Move to Belgium

For purists, this is a must. Only in the Senne valley of Belgium can the brewer encounter the true wild yeasts of lambic beers which contain the essential bacterias, Bretanomyces bruxellensis and B. lambicus. In fact, to move to Belgium is the only way to enjoy an authentic lambic experience without compromising the eco-friendliness of the endeavor with trans-Atlantic shipping.

Step #2: Mash Up

A lambic wort is traditionally comprised of 60-70% barley malt and 30-40% unmalted wheat.

Guilt-Free Beer Guzzling: Top Five Sustainable Suds

Who’s thirsty?

Between the barbecues, national holidays and beach vacations, cold beers become a necessity in many households over the summer months. As we pay more attention to the way our food is grown, harvested and transported, perhaps we owe it to the environment to be as vigilant with our beer. But how easy is it to find environmentally-conscientious breweries?

Beer brewing is not the most environmentally-friendly of activities, particularly regarding water usage. On average, six gallons of water are required to brew one gallon of beer - a ratio that must be drastically reduced in dry areas. Wastewater, carbon emissions and huge energy generators also contribute to the environmental sins of the industry.

But more breweries are taking notice of the eating public’s environmental awakening. While the biggest multinational breweries are beginning to make structural changes that promote sustainability, most of the greenest beers are (unsurprisingly) local and regional ones. Microbreweries are great agents of change because they interact with the communities that surround them. Their smaller size and community feeling make them more amenable to change, so it is easier to petition them and request more sustainable practices. Below are the top five eco-minded, North American mid-sized breweries:

The Lindberg Report Podcast: Hops Have Feelings Too!

As we approach another St. Patrick’s Day celebration, I think it only appropriate to bring everyone’s attention to PETH. Recent news stories indicate there is a shortage of hops, mainly because farmers are turning their attention to growing corn, soybeans and other food crops for the manufacture of ethanol and biodiesel.

While recording interviews for our Greening the Golden Years podcast series, I received an email from a senior, Mr. John Lane, who’s become very interested in a group called “PETH,” but he failed to say what it was all about. So, being the curious one, I called him and had the most “interesting” conversation. Look out, PETA — here comes the People for the Ethical Treatment of Hops.

Enjoy the day, and, have one for the hops.
