About a week ago I was in my basement pouring myself a fresh pint of hand-crafted beer when I noticed something odd. My most recent five gallon batch of beer, a dark and chocolate-y stout, had an unnattractive scum formation on the top of it, what we brewers refer to as a pellicle. This is the tell-tale sign of an infection by bacteria or wild yeast; in other words, not good. My stout, I thought, is ruined, which was a huge bummer since I don’t have anything dark on tap right now. A couple of days later I was describing this discovery to the co-owner of our local home brewing supply shop and his ears perked up. He began trying to convince me that I was onto something, and went into some detail about the effects of particular bacteria and wild yeast on beer flavors. His was an excitement born of a passion for sour beers, that unpredictable breed of beer rapidly growing in popularity among craft beer geeks. Mine was simply a bewilderment that one could have use for soured beer.
Unrelated but related, just today I was thinking about American lagers. Those who are familiar with the Beer Judge Certification Program (BJCP) may also be aware that there is an entire style category devoted to light lagers (style category #1, as a matter of fact). The first American lager style in this category: Lite American Lager. Yes, that bane of every craft beer lover’s existence is style #1A in the list of beer styles maintained by the preeminent beer judging organization in the world. But as bad as Lite American Lager is, the other American lagers in this category aren’t a whole lot better – at least not to me. When the description for a beer states that “strong flavors are a fault,” I’ll pass on a sample, thank you very much.
These two experiences are related in that they got me to thinking about what constitutes bad beer. When I talk to my craft beer friends about beer, we all tend to assume we share the same definition of bad. Bad beer is beer make by Budweiser or Coors or Miller. Bad beer is a skunky bottle of Corona, or a tasteless can of Coors Light. Corporate beer is bad beer, especially anything that might find itself described by the first three styles listed under BJCP style category #1.
Interestingly sour beer – which has become the darling beer “category” in the booming craft beer industry – is by definition “bad beer.” Sour beer is beer that has had microbial life other than cultivated brewer’s yeast introduced for the express purpose of producing unique, odd and potentially repulsive flavors, most of which are sour in nature. What makes this so odd is that we brewers typically go through a tremendous amount of effort to keep these beer-souring critters out of our beer. This is why most brewers offer up their first three tips of brewing as one and the same: sanitize, sanitize, sanitize. This is why a majority of the effort involved in brewing beer is related to cleaning and sanitizing. If you as a brewer do chance to get an infection of brettanomyces (wild yeast) or lactobacillus (souring bacteria) or something even “worse”, your oatmeal stout is going to taste like shit.
Or is it? It just may be that the very beer you thought went “bad” actually went “good” in a completely unexpected and unpredictable way. This is where the definition of bad beer gets tricky. To craft beer lovers, corporate beer is bad because it’s low on taste, or big on tastes that we just don’t like (e.g. skunky, corn-like, etc.). However, corporate beer is brewed by experts in the industry who posses amazingly sophisticated quality control programs and equipment. If any beer can be said to be good, i.e. not contaminated, it’s the high volume American “lights.” But hand a barrel-aged sour ale to a Bud Light fan and see if he doesn’t immediately identify that your beer has gone bad. That $18.00 bottle you couldn’t wait to get your hands on may well be the worst beer he’s ever tasted.
So what is bad beer? Intriguingly (and frustratingly) this is a truly subjective thing. This should be obvious, I know. In fact, the more I think about it the more obvious it is. Of course taste is subjective; we don’t all eat or enjoy the same foods, and beer is no different in this regard. What’s interesting about “good” and “bad” as it applies to beer, though, is that organizations like the BJCP exist for the primary purpose of helping us identify what’s good and what’s bad. We’re not talking about a bunch of paunch-bellied drunks swilling beer saying, “Yep, this one’s good”. We’re talking about serious research, both gustatory and historical, all condensed to a compendium of beer and flavor information and spread through a large network of beer enthusiasts and professionals, all dedicating their time to promoting “good” beer. So given that all of this effort has gone into defining what makes beer good, it seems like some of the subjectivity would be removed from the process. Granted, the BJCP also lists some sour beers (style category #17), but here again there are parameters of some sort, and a finite list of styles that are sour. The craft beer industry is not, by and large, limiting its sour offerings to lambics, gueze and Flander’s Red.
Okay, so if taste is subjective and therefore bad beer is in the tongue of the beholder, what’s the point of writing a blog post about it? I guess that for my part I think it’s important for craft beer lovers to recognize a couple of things. The first is that, just because you don’t like a beer doesn’t mean it doesn’t have it’s place. When you get past the obnoxious marketing and the fact that light beer is essentially tasteless, you realize that there are some damn fine brewers making this stuff. It’s not an easy feat to produce millions of barrels of lager with such flavor consistency; it’s actually damn complicated. And on a hot summer’s day when the lawn work nearly sucked your body dry you sweat so much, the Champagne of Beers may be the best beverage you’ve ever tasted. Alternatively sour beers are not always good. Frankly some of them are nasty, unless you love the taste of straight vinegar. However, for people who like that sort of thing, $18 is not too much to pay for a beer gone “bad.” In the end you should just drink what you like, support good breweries and don’t be afraid to waste a little time debating what makes beer good or bad. Just don’t expect to be right.
