Pale Lager: The Pleasures of 'Beer-Flavored Beers'

Pale Lager: The Pleasures of 'Beer-Flavored Beers' Primary Image

Golden lagers don’t pounce on you like a needy puppy, humping your leg and looking for approval. You have to come to them, meet them on their own terms, and live with them for a while. Slow down and pay attention. Only then will they reveal their charms.

It’s easy to feel the impact and complexity of imperial stouts and triple IPAs. Their sensory qualities blast you with layers of malt plus the bitter power and aromatic richness of hops. But what about what my brewer refers to as “beer-flavored beers”? They may be delicate and easy, but they’re not “simple.” Intensity is not the same as complexity. They are not as Instagram-friendly. You need more than a few sips to pass judgment. It takes some time to peel apart the layers. Drinkability means you can have more than one; to find that in a characterful beer is a delight.

These beers present a small target for the brewer, so the recipe choices are limited. Only the palest malts will brew a straw- or golden-colored beer. Hops, while important, have clearly defined roles of being subtle and Noble and quintessentially European in character. Lager yeast is the least flavorful of all brewing strains because it ferments cool, to limit the production of yeast-specific flavors such as fruity esters. Step outside those boundaries, and the beer becomes something else.

Despite these limitations, a good brewer can stay inside the box while creating something with depth and personality. Most pro brewers I know consider a perfect pilsner or helles to be the peak of their art and craft. They know how difficult it is to brew something that is so easy to enjoy but that, with reflection, has secrets to share. That’s why pale lagers are brewers’ beers.

Bright Evolution

Pale beers had been brewed in various times and places over the millennia, but something special happened in 1842 in Plzeň, Bohemia, now a part of the Czech Republic. The town fathers had a brewery built, and someone had the idea of combining a newly developed pale malt with a dose of perfumey hops and fermenting it with lager yeast. It was a sensation. Beers styles often evolve gradually, hitting their stride over years or even decades. Not this one. The innovation, pilsner, changed beer forever. Bohemian pilsners today—in Czech called světlý ležák, pale lager, as pilsner there refers specifically to beer from Plzeň—are often only a tad darker and a little maltier than their German cousins.

By the 1870s, pale lagers had taken hold over Europe and spread to the farthest reaches of the earth. Sometimes the world is just ready for something new. After pilsner splashed onto the scene, German brewers knew they needed something to compete. Their version was similar: modest in alcohol, pale gold in color, but a little drier and less lush, and well-differentiated by hops. German hops, especially Hallertau, have a drier, more herbal personality than the Bohemian Saaz, and this imparts a different personality to their “pils.” Today, German pils ranges from relatively balanced in the south to quite bitter in the far north, with some brewery-to-brewery variation.

Meanwhile, in Munich, a different style evolved and emerged. The water there is harder—not ideal for making pale, hoppy beers. Helles means “light”—in appearance, not necessarily in body and intensity. Because of its lower hop rate, it works with the limestone in the water and may also better suit Bavaria’s taste for maltier beers, such as the brown dunkels that were once dominant there. Helles is made from the same grain bill as a pils, but with minimal hopping, the malt really shines.

One more pale German lager, Dortmunder export, is a rarity today, but there are craft-brewed versions of it in the United States and globally. In terms of hops/malt balance, it’s somewhere between helles and pils, but typically has about 1 percent more alcohol by volume.

Those are the classics, but when you get beyond Central Europe, the boundaries are less distinct. There are beers that intergrade among the three classics, even veering off a little. But go too far, and you’ll have to call it something else.

The Elements of Golden Lager

Because they are so pale, these styles are highly dependent upon their base malt, and brewers have a number of choices. Pilsner-style malt is available worldwide, but there are regional differences. European pilsner malts are usually more aromatic but are generally the most expensive. Bestmalz in Germany, for example, makes a “Heidelberg” malt of very low color, and along with that comes a clean grassy/hay note.

For more than a century, American malting barley was bred for the needs of large breweries. What they wanted, in addition to economy, was “neutral” malt—a word we can interpret as “bland.” So the plain ol’ North American pilsner malt, most commonly made from Metcalfe or Copeland barley strains, will have a delicate flavor, sometimes with a bit of white bread and a hint of grassiness. You won’t find that malted-milk aroma that many European malts have.

Fortunately, growers more recently have bred new varieties that are much more flavorful in the glass, with craft beer in mind. Synergy, from Montana State University, promises—and delivers—a European character. Full Pint, developed at Oregon State, is described as having a “fresh salted popcorn” flavor, but we’ve found it intermediate between the standard U.S. pils malt and European types.

Many brewers add super-pale Carapils-type crystal malt that can add a little extra body, although it can be hard to notice the effect when you drink the beer. A few percent of Vienna or light crystal (10°L) can add a nice depth and more malty, sweet-caramel flavors. Anything darker—Munich malt, for example—starts to work against the style with too much toasty character.

Virtually all pale lagers were originally brewed with a decoction process like the rest of the lager family. The original, Pilsner Urquell, still uses a triple-decoction mash. In the days when metal vessels were prohibitively expensive, this technique employed a wooden mash tun along with a copper kettle to heat a portion of the mash to boiling before adding it back, creating temperature steps in the mash. Because decocting involved a fixed volume of boiling mash, the temperature steps could be reliable in an age before thermometers. It’s time-consuming and energy-intensive, which is why the practice is less common today (outside of some German breweries and virtually all Czech ones). It also adds a bit of color and a hint of caramel, acceptable style traits in Bohemian pilsners. Outside of the neutral rice or corn used in American-style mass-market lagers, the use of adjuncts such as wheat or oats in classic lagers is rare to the point of heresy. This, you will recall, is the land of the Reinheitsgebot.

Classic pale-lager hops are “Noble,” a quality that is much prized, little understood, and gerrymandered beyond any real meaning. This title is bestowed upon four regional “landrace” (spontaneously developed rather than intentionally bred) varieties: Hallertau Mittelfrüh, Saaz, Tettnang, and Spalt. The last three are more closely related to each other than to Hallertau and present a bright, super-clean hop aroma we don’t really have good words for. The classic descriptor is “spicy,” but to me this is a placeholder for “don’t-know-what-else-to-call-it-hoppy.” Hallertau veers much more into the herbal, with hints of thyme or mint. In a crisp, super-pale beer, Hallertau can really nail its dry, refreshing character.

There have been many newer hops bred all over the world from German and Czech parentage. These upgrade the classics in terms of yield, hardiness, and other agricultural characteristics, better adapting them to their new homes. Varieties such as Liberty, Saphir, Perle, Mount Hood, Crystal, Pacifica, and others can come pretty close to the classics but may be a bit bolder than their progenitors, so they need to be used judiciously.

The whole idea of lager yeast is that it shouldn’t add much of anything: Just get out of the way and let the ingredients shine. Working at the bottom end of its temperature range, the yeast produces very little in the way of fruity esters, although I’ve seen well-trained noses pick them out. The same goes for spicy phenols, which are rarer still. Some lagers do show a bit of sulfur: either a burnt-match sulfur dioxide or a rotten-egg hydrogen sulfide. They’re an expected part of lagers, but fortunately they dissipate quickly and don’t detract from the experience. A long, cold conditioning adds smoothness.

So, get a nice, tall pilsner glass, fill it with your favorite classic pale lager, and give it your full attention. Clear your schedule; this might take more than one.
