Editing Pilsner (section)

===Modern developments===
The introduction of modern refrigeration to Germany by [[Carl von Linde]] in the late 19th century eliminated the need for caves for beer storage, enabling the brewing and storing of cool fermenting beer in many new locations.<ref>"Altbier im Alltag" by Genno Fonk, 1999, page 11</ref>

Until 1993 the [[Pilsner Urquell]] brewery fermented its beer using open [[barrel]]s in the [[wine cellar|cellar]]s beneath their brewery. This changed in 1993 with the use of large cylindrical tanks. Small samples are still brewed in a traditional way for taste comparisons.{{cn|date=October 2024}}

A modern pale lager termed a ''pilsner'' may have a very light, clear colour from pale to golden yellow, with varying levels of hop aroma and flavour. The alcohol strength of beers termed pilsner vary but are typically around 4.5%–5% (by volume). There are categories such as "European-Style Pilsner" at beer competitions such as the [[World Beer Cup]]. Pilsner style lagers are marketed internationally by numerous small brewers and larger conglomerates.{{cn|date=October 2024}}
