Malty and rounded, with a soft finish and heavy sulphur production during fermentation that disappears entirely with lagering. Nerve-racking the first time.

Pitching it
A lager needs roughly twice the cell count of an ale at the same gravity, pitched cold, into well-oxygenated wort. Under-pitching a lager produces sulphur and diacetyl that weeks of cold conditioning will not fully remove.
Other lager strains
German Lager
73-77%Crisp and clean, with a malty finish. Needs a large pitch, cold fermentation and a diacetyl rest before it is packaged. The Weihenstephan 34/70 lineage, and the most-used lager strain on earth.
Czech Lager
70-74%Finishes fuller than a German strain, which is where a Czech pale lager gets its body. Slow, sulphury early, and worth the wait.
California Lager
67-71%A lager strain that works at ale temperatures, which is how steam beer exists. Clean at the warm end of its range where most lager yeasts would throw sulphur.
Mexican Lager
72-76%Clean and slightly fruitier than the German strains, suiting the lightly sweet, corn-inflected lagers it is named for.
Munich Lager
73-77%Bred for the dark Bavarian styles: emphasises malt depth rather than crispness, and finishes with a fullness that suits a dunkel or a bock.
