What is lager?

Beer made with a cold-loving yeast and stored cold to mature. How it’s made, where it came from, every type from pilsner to dunkel, and the alcohol-free lagers worth buying.

The short answer

Lager is beer fermented with bottom-fermenting lager yeast at low temperatures, around 5–10°C,[1] and then usually matured cold for weeks before it’s packaged. That cold maturing is called lagering, from the German lagern, “to store”.[2] Lager was first brewed in the 15th century, with a yeast that turned out to be a hybrid of ordinary ale yeast and a wild, cold-loving species.[3] Most lager is pale, like pilsner and helles, but not all of it: a schwarzbier is a “black beer”.[4] Unhopped’s directory lists 136 alcohol-free lagers, from Bavarian helles to Czech-style pils.

This guide covers how lager is made, where its yeast came from, the history from Bavaria to Plzeň, every main type, and how brewers take the alcohol out. If you just want something to drink, skip to six alcohol-free lagers to try, or see the nineteen we rank, with prices.

What is lager?

The simplest definition is the yeast. In the words of the BJCP style guidelines, “American brewers and most other craft brewers call beers ales if they use top-fermenting (ale) yeast” and “lagers if they use bottom-fermenting (lager) yeast.”[5] Lager yeast works at lower temperatures, 5–10°C, and sinks “quickly to the bottom of the vessel”.[1]

Then comes the part that gives lager its name. After fermentation, the beer is stored cold on its yeast for “several weeks, if not months”: traditionally up to three months, though 21 days is typical today.[2] German brewers put the weight there. The same guidelines note that “Germans think of ale as a type of English beer, and lager as a method of conditioning beer.”[5]

How is lager made?

The brewing starts like any beer: malted barley is mashed to release its sugars, the liquid is boiled with hops, then cooled and fermented. Three things make it a lager: the yeast, the cold, and the time.

Where did lager yeast come from?

Until 2011, one of its parents was unknown. That year a team led by Diego Libkind reported in PNAS that lager yeast, Saccharomyces pastorianus, is “a domesticated species created by the fusion of a Saccharomyces cerevisiae ale-yeast with an unknown cryotolerant Saccharomyces species”, and that they had found the missing parent. They named it Saccharomyces eubayanus. It came from southern beech forests in Patagonia, and its draft genome is “99.5% identical to the non-S. cerevisiae portion of the S. pastorianus genome sequence”.[3] In other words, lager yeast is part ale yeast and part a wild yeast that tolerates the cold.

Where did lager come from?

Lager beer was “first brewed in the 15th century”.[3] In Bavaria, the Reinheitsgebot of 23 April 1516 ruled that “no other items be used for beer than barley, hops, and water”.[8] The modern styles came in the 19th century. Vienna lager and Märzen were both “first brought to market in 1841”, by Anton Dreher and Gabriel Sedlmayr, who were close friends.[9] On 5 October 1842 the Bavarian brewer Josef Groll, working in Pilsen, “brewed the first batch of the golden lager that came to be known as pilsner beer.”[10] German brewers adapted it, and German pils was first brewed in the early 1870s.[11] Munich answered with helles: Spaten introduced the first “real” helles on 21 March 1894.[12]

Oktoberfest followed the same path. Märzen, a stronger “March beer” lagered in cold caves over the summer, was the amber lager served at Oktoberfest from 1872 until 1990;[13] since 1990 most of the beer served there has been the paler festbier.[14] Our alcohol-free Oktoberfest guide covers the German beers that carry on the tradition without the alcohol.

The types of lager

The BJCP guidelines describe more than a dozen lager styles. These are the ones you’re most likely to meet, with an alcohol-free example from our directory where there is one. The pale ones get their own guide: pilsner vs lager, which also covers Czech vs German pils and helles.

Lager styles and their strength range in the BJCP 2021 guidelines, with an alcohol-free example.

Is lager always pale?

No. The German word hell or helles “simply means ‘pale’”,[12] and its opposite is dark. Munich dunkel is “a traditional malty brown lager from Bavaria”,[16] and schwarzbier, literally “black beer”, is medium to very dark brown, “almost never truly black”.[4] Märzen, an amber lager, sits in between.[13] Among the darker alcohol-free lagers we list is Estrella Galicia 0.0 Tostada, a toasted, dark amber 0.0% lager, which Dry Drinker had sold out when we checked.

Lager vs ale

Ale uses top-fermenting Saccharomyces cerevisiae, which likes “to ferment quickly (2–7 days) and at higher temperatures 15°C–24°C”;[6] lager ferments colder, more slowly, and is then lagered. The line isn’t always clean: Germans would “speak of Kölsch as a top-fermented lager beer, not an ale”.[5] The full comparison, with a table and the hybrids, is in lager vs ale, and Kölsch has a guide of its own: what is Kölsch?

How is alcohol-free lager made?

Many alcohol-free lagers are brewed as full-strength beer first and have the alcohol taken out. Heineken says Heineken 0.0 is “double brewed while alcohol is removed and blended with natural flavours”, using vacuum distillation, and that it contains less than 0.03% alcohol.[17] Lucky Saint says its lager “is brewed the same way as a full-strength beer” and is “fermented and conditioned for 6 weeks” before a vacuum distillation process removes the alcohol.[18] According to their beer pages on Unhopped, Days Lager is brewed as a traditional helles then de-alcoholised, and Jever Fun Pilsner is brewed as a full beer with the alcohol then gently removed. Krombacher Pilsner takes a different route, combining a stopped fermentation with a gentle dealcoholisation.

Some small brewers skip the removal step and brew to below 0.5% from the start: Jump Ship Yardarm Lager, from Jump Ship in Midlothian, is one. Our guide to how alcohol-free beer is made explains the methods. On strength: Heineken 0.0 and Peroni 0.0 are 0.0%, while many craft lagers are 0.5%. UK government guidance, which is voluntary, keeps the term alcohol-free for 0.05% ABV or below, though many beers up to 0.5% are sold in the UK as alcohol-free. More in our 0.0% vs 0.5% guide.

Questions people ask

Is lager a type of beer?

Yes. Lager is beer made with bottom-fermenting lager yeast at low temperatures and usually matured cold. Ale is the other main family, made with top-fermenting ale yeast at warmer temperatures.

Why is it called lager?

From the German lagern, “to store”. After fermentation, lager is stored cold on its yeast for weeks, a stage called lagering.

Is pilsner a lager?

Yes. Pilsner is a pale lager style, first brewed in Pilsen (Plzeň) in 1842. Every pilsner is a lager; not every lager is a pilsner. See pilsner vs lager.

Is lager stronger than ale?

Not as a rule. Strength depends on the style. In the BJCP guidelines a Czech pale lager is 3.0–4.1% and a doppelbock 7.0–10.0%, while an ordinary bitter, an ale, is 3.2–3.8%. The alcohol-free lagers we list are 0.0% to 0.5%.

What is the best alcohol-free lager?

Lucky Saint Unfiltered Lager has our highest score for a lager, 8.7 out of 10. Our best alcohol-free lagers ranks nineteen, with prices.

Is Heineken 0.0 really alcohol-free?

Heineken says Heineken 0.0 contains less than 0.03% alcohol, under the 0.05% that UK guidance keeps for the term alcohol-free.
