Kellerbier is a German unfiltered beer style with lower alcohol content, typically under 5%. It originates from Franconia and is known for its natural carbonation and fresh taste.
How it is made
Kellerbier is unfiltered and unpasteurized. The special brewing process involves sealing barrels with corks or caps just before fermentation completes, allowing carbon dioxide to dissolve in the beer and creating a more carbonated beverage compared to regular cellar beer.
History
Kellerbier was first produced by home and amateur breweries in Franconia. The name comes from the German word 'Zwickel', meaning 'tap for sampling', which was used to check the fermentation process.
How it is served
Kellerbier is rarely exported and can typically only be found in Germany and some neighboring countries. It is served fresh from the barrel, preserving its natural carbonation and flavors.
