BioTorsdag: The Rediscovery of European Farmhouse Yeast

Once common across Europe, farmhouse brewing was thought to have disappeared in the 20th century. Recent discoveries in remote areas, however, have revealed that both the tradition and inherited ancestral yeasts are still alive.

Historically, farmers in Europe brewed their own beer from their own grain, but the tradition largely died out in the 20th century. Over the last decade or so researchers have to their surprise discovered that the tradition is still alive in remote areas, and, even more surprising, some of the brewers still have the yeasts they inherited from their ancestors. The talk will tell the story of how this discovery was made, how these yeasts are used, and how they are different from the modern yeasts that commercial brewers are used to.

Lars Marius Garshol is a Norwegian author, speaker, and blogger who writes about and researches traditional brewing and beer.
