American Craft Beer Week – May 12-18, 2014
Ah, good ol’ beer. There’s the cheap, light, basically glorified carbonated water with a slight kick, there’s the more expensive big name imports, and increasingly, there’s small to mid-sized ‘Craft Brewers’ who produce seasonal beers and everything from amber light to deep chocolate brown brews. Lots of people enjoy a good beer. The closest city to my homestead – Asheville, North Carolina – has gained quite a reputation as Beer City USA, with some serious competition in places like Portland, Oregon and Grand Rapids, Michigan. Many other cities are boasting successful microbreweries as well. Microbrews have become so popular, in fact, that many of the Big Beer brewers are buying in and happily marketing the stuff, or brewing big batches of seasonal beers under their own brand names.
Humans have been enjoying beer for just about as long as civilization has existed. More than 6,000 years ago brewers in Mesopotamia and Egypt were recording recipes for beer. Pharos were entombed with yeast and barley so they could enjoy their favorite brews in the afterlife! By the second millennium b.c.e. the Babylonians boasted 20 different types of beer. The Romans were fonder of wine, but beer was still brewed in Britain, Eastern Europe and Germany. By the Middle Ages home brews were a staple of the family diet, as beer was safer to drink than plain water. Plagues and famines in Europe left the task of making beer, mead and wine fell to monks. Who built fine breweries to provide pilgrims with food, drink and shelter.
There are a couple of bulky by-products of the beer brewing process – spent grain (sprouted and dried to produce “malted” mash), and with the introduction of hopped beers from Holland in the 1500s, used hops. Since these by-products are organic, the practice of recycling the waste products came naturally. The spent grain mash is used as a sweet feed treat for cows, sheep, lamas, horses, chickens and other livestock, while used hops are composted and/or used as mulch. Some microbreweries offer their spent grain back to the farmers who help supply the grain, or sell it cheap. The grain is usually still damp from the brewing process, so it goes quickly to the animals. Who appear to love it.
According to the website Craft Beer, the cycling of grain from farmers to brewers and from brewers back to farmers is the “farm-to-foam, foam-to-farm” cycle. At the Piney River Brewing Company’s 80-acre farm in the Ozarks, the cows eagerly abandon their pasture when they smell sweet mash on brewing day, get as close to the brewhouse as they can, and moo loudly for their bucket of spent grain. A couple of Colorado brewers donate spent grain to a local dog biscuit bakery, and the dogs apparently love it too. The Brooklyn Brew Shop’s Spent Grain Chef offers recipes for such delicacies as spent grain grapefruit bars, spent grain corn dogs, spent grain mini carrot cupcakes and more. The Alaska Brewing Company uses their spent grain in a biomass steam boiler to generate steam used in the brewing process. Brewers usually give the spent grain away to farmers if they’ll come get it, or sell it quite cheaply. Widmer, a larger brewery, sells theirs for $30 a ton. One dairy farmer near Portland, Oregon says “It’s a premium product. I pay virtually nothing. But it’s like putting honey on your cereal. It makes the cows want to eat more and we notice it in their [milk] production. That farmer goes through 20 tons of spent grain a week for his 300 cows. That’s feed he would otherwise have to purchase, adding to the cost of the milk his cows produce.
With all this sound cycling and recycling between the food supply and the beer supply, the Food and Drug Administration [FDA] just had to weigh in. Whether on behalf of the Biggest of the Big Boyz in grain agriculture (Cargill, ADM, etc.) or just because government regulators figure they have to think up some regulations nobody’s thought of before, they came up with a new rule on animal feed that would bring the spent grain from beer brewing under its regulation and possibly raise the price of beer generally.
