Oktoberfest beers - Märzen and Festbier, how they differ
Oktoberfest is the biggest beer festival in the world, a Munich celebration drawing millions of people, giant mugs and music. But which beer is actually drunk at Oktoberfest? Many people associate it generally with a Bavarian lager, not knowing that behind the festival stand two specific, interesting styles: Märzen and Festbier. These two beers, though both tied to Oktoberfest, differ in history, malt and character, and getting to know them opens a fascinating chapter of Bavarian brewing. Where did these styles come from, how does the rich, malty Märzen differ from the lighter, golden Festbier and which beer is poured at the Munich festival today? Here is a practical guide to Oktoberfest beers: their history, the differences between Märzen and Festbier and how to recognise and appreciate these classic Bavarian styles.
Where Märzen came from
Let us start with history, because it explains everything else. Märzen origins trace back to 1553 and a Bavarian decree forbidding brewing in the warm months, to prevent bacterial infections. So brewers made enough beer in March to last until autumn - hence the name Märzen, that is March beer. This beer was brewed stronger and maltier, so it would keep better through the summer in cool cellars. The modern Märzen style traces back to 1841, when the Spaten brewery created the first recipe for the style. Finally, Märzen became the official beer of Munich Oktoberfest in 1872. It is a fascinating history in which law, the seasons and the need for storage shaped a specific beer style. Understanding that Märzen is literally March beer, brewed in reserve for summer, explains its strong, malty character. The history of Märzen is the history of Oktoberfest itself.
What Märzen is
Since we know the history, let us look at what Märzen is in taste. It is a bottom-fermented beer, a lager, of a characteristic, rich malt profile. The heart of Märzen is the malt: a generous malt load, with hops present only to keep the beer from being too sweet. Märzen has rich, bready, toasty malt notes, leading to a moderately bitter and quite dry finish. It is a full-bodied beer of amber-copper colour and a pronounced, malty character. It uses Munich malt, which gives it depth and toasty notes. The result is a beer that is filling, smooth and deeply malty, ideal for an autumn festival. Märzen is a classic example of a malt-focused beer, where hops play a secondary role, balancing the sweetness. Its richness and amber colour are the hallmark of a traditional Oktoberfest beer. It is a style of character, made to taste of the fullness of malt.
Where Festbier came from
The history of Oktoberfest does not end with Märzen, because a new style appeared over time. Festbier was created by brewers at the Paulaner brewery in the 1970s as a less-filling version of the Märzen Oktoberfest beers. This is a key change: Festbier arose as a response to the need for a lighter beer that is easier to drink in large quantities during a celebration lasting many hours. Over time Festbier replaced Märzen at Oktoberfest itself - the lighter, golden Festbier displaced the heavier Märzen at Oktoberfest around 1990. This shows an interesting evolution: the traditional, rich Märzen gave way to the lighter, more approachable Festbier as the official beer of the festival. The change came from practice: at a festival where litres of beer are drunk for hours, a lighter style simply works better. Festbier is the newer, lighter answer to the Märzen tradition, now dominant at the Munich festival. The history of both styles is the history of changing tastes.
What Festbier is
Let us look at how Festbier differs from Märzen in taste and appearance. Festbier is far less malty, less intense and lighter in body than its Märzen predecessor. Although Festbier is also a malt-focused beer, the hops have more presence in it, and the malt bill is far simpler. Festbier is brewed with majority pilsner malt, unlike Märzen, which uses Munich malt. This difference in malt explains everything: pilsner malt gives Festbier a golden colour, a lighter body and a cleaner, less bready profile. The result is a beer resembling a strong, fuller pilsner more than a rich Märzen. Festbier is golden, smooth and refreshing, but still with a noticeable malty character and a higher strength than an ordinary lager. It is a beer designed to be drunk in large quantities, lighter and more approachable, yet still festive and characterful. Festbier is the modern face of Oktoberfest beer.
Märzen versus Festbier - the key differences
Let us line up the two styles, because then the differences become clear. First, malt: Märzen uses Munich malt, giving rich, toasty notes, and Festbier pilsner malt, giving a lighter, cleaner profile. Second, colour: Märzen is amber-copper, and Festbier golden. Third, body and intensity: Märzen is fuller, heavier and maltier, and Festbier lighter, simpler and more approachable. Fourth, hops: in Festbier they have more presence than in Märzen, where they play a background role. Fifth, history: Märzen is the older, traditional style, and Festbier the newer, lighter version from the 1970s. Put most simply: Märzen is a rich, amber, malty beer for a lover of tradition, and Festbier a golden, lighter, refreshing beer for drinking in large quantities. Both are bottom-fermented lagers of elevated strength, but of entirely different character. This difference is the essence of the evolution of Oktoberfest beer.
Which beer at Oktoberfest today
Since we know both styles, which is actually poured at the Munich festival today? The answer is interesting: although Märzen was the historic, official Oktoberfest beer, today Festbier dominates. The lighter, golden Festbier replaced the heavier Märzen at the festival itself around 1990, because it is better suited to many-hour celebration and drinking by the litre. Märzen, however, remains alive and prized, especially outside Germany, where many breweries brew Oktoberfest-style beers precisely as an amber, malty Märzen. This creates an interesting situation: at Munich Oktoberfest itself you mostly drink Festbier, but beers sold around the world as Oktoberfest are often the traditional Märzen. Both styles are therefore tied to the festival, just at different times and places. Märzen is the traditional essence, and Festbier the contemporary reality of the Munich festival. It is worth knowing both, to consciously choose a beer for your own Oktoberfest.
How to drink and what to pair
Both styles taste best served and paired with thought. First, serve them chilled but not ice-cold, because too low a temperature mutes the malty character, especially in Märzen. Second, reach for a traditional mug or glass, the kind in which this beer is drunk in Bavaria. Third, both styles go great with hearty Bavarian cuisine: roast meat, sausages, pretzels, pork knuckle, because their malty fullness balances fatty, meaty dishes. Fourth, Märzen, being fuller, copes better with heavier dishes, and Festbier, lighter, works for lighter food and drinking in larger quantities. Fifth, remember their higher strength and drink in moderation. These beers are also a natural choice for autumn, much as winter beers are for the colder months. A conscious serving and choice of food raise the pleasure of these classic Bavarian styles. Oktoberfest beer tastes best in the company of hearty cuisine.
Where their character comes from
It is worth understanding where the character of both beers comes from, because it deepens the appreciation. The key is malt and the way of brewing. Märzen draws its rich, toasty character from Munich malt and the tradition of brewing a stronger beer in reserve, which is decided by the role of malt in beer. Festbier owes its lighter, golden profile to majority pilsner malt and a simpler recipe. Both are bottom-fermented lagers, brewed by a method that gives a clean, smooth character, unlike top-fermented beers, which we cover in the lager versus ale difference. Both also fit within the tradition of the German purity law, which limits ingredients to malt, hops, water and yeast. This shows that the character of these beers comes from specific, conscious brewing decisions rather than chance. Understanding the role of malt and the brewing method lets you appreciate why Märzen and Festbier taste the way they do. Their character is the fruit of Bavarian tradition.
The essentials in brief
Let us gather it up. Oktoberfest rests on two styles: Märzen and Festbier. Märzen is the older, traditional style, whose roots reach back to the 1553 decree on brewing in March in reserve for summer; it is a rich, amber, malty beer from Munich malt, the official Oktoberfest beer from 1872. Festbier was created in the 1970s as a lighter version, and around 1990 replaced Märzen at the festival itself; it is a golden, lighter beer from pilsner malt, with more hop presence. The key differences are malt, colour, body and intensity. Today Festbier dominates at Munich Oktoberfest, but beers sold around the world as Oktoberfest are often Märzen. Both go great with hearty Bavarian cuisine. Now you know which beers are drunk at Oktoberfest and how these two classic Bavarian styles differ.
