Although '''landrace''' is a term used in many areas, this page will be using it as descriptors of a yeast or mixed culture that derives from a traditional farmhouse/landrace brewing cultures from around the world (note that kveik, while considered "landrace" yeast, is split off onto its [[Kveik|own page]] for wiki management purposes). This term was first used to describe yeast by [https://www.frontiersin.org/articles/10.3389/fmicb.2018.02137/full Tyrawa et al. (2018)] to describe traditional Norwegian kveik yeast <ref name="Tyrawa_2017">[https://www.frontiersin.org/articles/10.3389/fmicb.2018.02137/full Traditional Norwegian Kveik Are a Genetically Distinct Group of Domesticated Saccharomyces cerevisiae Brewing Yeasts.

The original owners of these yeasts pitch them at a wide variety of temperatures depending on the culture, anywhere from 5°C up to 40°C, but the majority being pitched at around body temperature. Some Finnish farmhouse brewers reported pitching their yeast at cooler temperatures (5-15°C).
