Lager — The Bottom-Fermentation Beer Guide
Lager is by far the most consumed beer type in the world. From the German word “Lagern” (to store), it is defined by bottom fermentation with Saccharomyces pastorianus yeast, which works slowly at low temperatures and settles at the bottom of the tank. The result: a clean, crisp, balanced beer where the yeast steps aside to let malt and hops speak. Born in Bavaria in the 15th century then perfected in Munich and Pilsen in the 19th century, the Lager family today covers a vast range — from blonde, malty Helles to nearly black Schwarzbier.

Frequently Asked Questions
What is the difference between a Lager and an Ale?
The difference is not the colour but the yeast and fermentation temperature. Lagers ferment at low temperatures (8–12 °C) with yeast that settles at the bottom (“bottom fermentation”), producing a clean beer. Ales ferment at room temperature (15–22 °C) with yeast that rises to the surface, producing more complex aromas (fruity, spicy).
Why are Lagers so popular?
Three reasons: industrial production is more stable (controlled fermentation), their neutral profile appeals to a wide audience, and they are very refreshing served cold. Heineken, Budweiser, Carlsberg and Kronenbourg — which dominate global sales — are all Lagers.
What is the origin of Lager?
Lager was born in Bavaria in the 15th century, when brewers noticed that low-temperature fermentation (in winter caves) produced a clearer, more stable beer. The invention of Pilsner in Pilsen (Bohemia) in 1842 by Josef Groll, followed by industrial refrigeration and pasteurisation, launched the worldwide spread of the style.
Which Lager should I try to discover the style?
To understand the foundation: Pilsner Urquell (the world’s first Pilsner) or Augustiner Helles (classic Munich). To explore the diversity: Spaten Oktoberfest (Märzen), Köstritzer Schwarzbier (black lager), Andechs Doppelbock (strong lager).
How should I serve a Lager?
Colder than an Ale: 4–7 °C. Pour gently to get a 2–3 cm head. Prefer a Pilsner glass (tall and narrow) for Pilsners, a krug or traditional mug for Helles, a tulip for stronger sub-styles.
