Pils, Helles, Export: the difference

Difference between Pils and Helles: bitterness is the key

In the glass, the two look nearly identical: golden, clear, with a white head. The difference lies on the tongue. Bitterness is measured in IBU, International Bitterness Units, which roughly indicate the level of dissolved hop bitter compounds. According to the 2021 BJCP guidelines, a German Pils sits at 22 to 40 IBU, a Munich Helles at 16 to 22. Where the Helles leaves off, the Pils is really just getting started.

Alcohol content barely separates the two: Pils runs 4.4 to 5.2 percent ABV, Helles 4.7 to 5.4. Original gravity—the malt extract in the wort before fermentation—also sits around 11 to 12 percent for both. Helles is a shade darker, 6 to 10 EBC versus 4 to 8 for Pils. EBC is the European color scale: the higher the value, the darker the beer. More important than the number is the impression. Helles tastes round, with bread and grain notes, while Pils finishes dry and hoppy, often with a herbal or floral aroma.

Where does Pils come from? Pilsen, 1842

The story begins in Bohemia, but with a Bavarian. Brewer Josef Groll from Vilshofen brewed the first batch on October 5, 1842, at the new Bürgerliches Brauhaus in Pilsen; it was first served on November 11. Bottom fermentation itself wasn't new—Bavarian brewers had long mastered it. What was new was a strikingly pale bottom-fermented beer with generous hopping. This suited the town's very soft, low-mineral water, in which hops come across as fine rather than harsh.

The beer has carried the name Pilsner Urquell since 1898. The word Pils itself is a generic term in Germany, free for any brewery to use. The Czech original, listed in the BJCP catalog as Czech Premium Pale Lager, is usually fuller-bodied and somewhat darker than a German Pils: 30 to 45 IBU, 7 to 12 EBC, often with a slightly sweet malt core. The German Pils is leaner, paler, and drier.

What is a Helles? The Munich answer

Munich's brewers answered the success of pale beers with a style of their own. Instead of cranking up bitterness, they focused on the malt. A Helles lives on pale barley malt, light hopping, and a long, cold maturation. It's meant to be easy-drinking without turning sweet. Munich's mineral-rich water would have made strong hop bitterness feel harsh anyway. Today, nearly every brewery treats its water, but the stylistic boundary has remained.

Münchener Bier (Munich Beer) has been registered as a Protected Geographical Indication, or PGI, in the EU register since July 18, 1998. This protects the origin, not the style. A Helles can be brewed anywhere, but it may only be sold under the name Münchener Bier if it comes from Munich.

The difference shows up most clearly at the table. A Helles pairs with Weisswurst, pretzels, and a simple Brotzeit snack spread, since it doesn't overpower anything. A Pils cuts through fat with its bitterness and suits fried or roasted foods. Temperature matters too: very cold, any pale lager feels leaner; slightly warmer, bread and honey notes emerge in the Helles, while hop blossom comes forward in the Pils. If you want to compare the two, pour them side by side and taste the Helles first, then the Pils.

Export: the fuller-bodied Helles from Dortmund

The name recalls export, and indeed Export stands for a slightly more robustly brewed beer. The style is associated above all with Dortmund. In the BJCP catalog it's listed as German Helles Exportbier: 12.4 to 14.3 percent original gravity, 5 to 6 percent ABV, 20 to 30 IBU, color 8 to 12 EBC. In bitterness, it sits between Helles and Pils; in body, it surpasses both.

Dortmund's hard, mineral-rich water once gave the beer a firm, slightly dry finish. Dortmunder Bier has also been a PGI since 1998. In southern Germany, by contrast, Export often denotes a somewhat stronger Helles, and the line between the two blurs. For choosing at the shelf, a simple rule helps: Pils for bitter, Helles for soft, Export for more malt and body.
