Among the more important questions beer drinkers should ask themselves is whether a beer is “pure.” Without nutritional information or ingredient lists, how is a beer drinker to know if a brewery is deserving of their hard-earned money? There may not be a method to determine this pre-purchase, but once a beer is poured and consumed there are simple techniques to determine if a brewery is one that should make it into your rotation of favorites. But first, let’s take a look at how the notion of “pure beer” came to be.

Reinheitsgebot, the old German Purity Law (and sound my dog makes when he sneezes) has been around longer than the United States has been a country. Developed in 1516, this doctrine was enacted to ensure that the beer produced was of premium quality using only four all natural ingredients: water, malt, hops and yeast.

In this day and age, the number of breweries in the U.S. adhering to this doctrine can be counted on one hand (two if you’ve lost a fight with your snow blower). The Germans believed that truly pure beer is unattainable. Like life itself, the journey (towards pure beer) is the goal.

What prevents a beer from being pure? From brewing techniques to ingredients, there is no shortage of methods breweries can use to further their beer from being pure. You may never wonder how your favorite beer is filtered, but would it surprise you to know that among the various methods some breweries use horse hooves and fish guts to filter beer? Use of these ingredients increases beer clarity (and the chance that you just threw up in your mouth a little). Personally, I’d rather a little sediment appear in my beer than drink something that got intimate with Nemo’s intestines. They can make fun of the ingredients craft brewers use all they want, but I bet most if not all craft beer is snail free. And while you may not be able to tell if a beer was made using these “ingredients,” you can tell if it’s pure in three easy steps:

Step 1: Rocky Head

Pour your beer into your favorite clean, rinsed glass so that when finished you’ve got a nice head on top. Don’t be shy with the pour- be aggressive without creating an overabundance of foam. A pure beer will have a rocky foam head, meaning it has a richness to it and the bubbles are not all the same size and shape. Beer that isn’t pure will have little to no head, and if it does, it’s thin and wispy.

Step 2: Lacing

After a few sips (or if you live in the Midwest, gulps) take a look at the side of the glass. A pure beer should have foam — or “lacing” — that clings to the inside of the glass. If you started with a clean, rinsed glass and you don’t see this lacing then chances are the beer you’re holding isn’t pure.

Step 3: Finish

Once you’ve finished that first glass, pay attention to any lingering flavors that remain on your palate. Pure beer finishes clean. Beers made with chemicals or unnatural ingredients will rarely- if ever- have a clean finish.

Once you’ve finished your beer, if you truly desire another (and even another after that), then that beer passes what we in the industry refer to as the “three pint test.”

If after three beers it passes the steps mentioned above, it didn’t become boring, and there aren’t any “off” aromas or flavors, that beer is well made and worthy of your attention. With virtually limitless options facing craft beer enthusiasts these days, there is no reason to waste your time with beers that aren’t.
