Hail to Ale: A Photo Essay You Can Raise a Pint To

Alumni, pints, engineering, and the quest for making the best beer. We dig into the science of fermentation with photos of brews and businesses cultivated by our alumni.

April 7 is National Beer Day. Michigan Tech has numerous alumni working in the brewing world, both near and far. Among them, nine breweries in Michigan, one each in Minnesota and Wisconsin, and a brewing system control panel fabricator. And on any given Friday, you’ll find numerous faculty, staff and students (of legal drinking age) meeting to discuss projects, collaborations and celebrating successes with a pint in hand.

Business and pleasure aside, brewing has a geeky side. There’s a great deal of science behind a fine pint of pale ale.

Water, malt, hops and yeast. Combine these ingredients in countless variations and the result is beer. But there’s more to brewing than throwing ingredients in a pot and boiling it. Change seemingly minute aspects of the process—a hotter or cooler boil, hops dropped at different time intervals, a yeast strain’s specific attenuation qualities, a cool or warm ferment, the addition of adjunct ingredients like honey, fruit or flowers—and the result is entirely different. Innumerable spreadsheets are devoted to calculating ingredient percentages. Many biology majors these days find employment in brewery labs, tending to yeast, a sugar-fiend of an organism that creates carbon dioxide and ethyl alcohol.

At the end of the batch, better living through chemistry only goes so far. Much like cooking, brewing is also an art, and one with a history that stretches back thousands of years. But beer is also more than an art because you can drink it.

Cheers!
