===Bjarne Muri's Olden Farmhouse Yeast===
It was initially found by Krogerus et al. (2018) that the single Muri strain recovered by Bjarne Muri is a hybrid of ''S. cerevisiae'' and ''S. uvarum'', and is most closely related to the beer 2 yeast group (kveik falls into the Beer 1 group; see [[Saccharomyces#History_of_Domestication|History of Domestication]] for more information on the beer yeast genetic groups) <ref>[https://www.frontiersin.org/articles/10.3389/fmicb.2018.02253/full A Unique ''Saccharomyces cerevisiae'' × ''Saccharomyces uvarum'' Hybrid Isolated From Norwegian Farmhouse Beer: Characterization and Reconstruction. Kristoffer Krogerus, Richard Preiss, Brian Gibson. 2018. DOI: https://doi.org/10.3389/fmicb.2018.02253.]</ref>. Unlike kveik, Muri is POF+ (phenolic) and STA1 (diastaticus). Krogerus then performed full genome sequencing on the Muri strain and discovered that it is a genetic match for WLP351 Bavarian Weizen yeast. This strain is either a contaminant (most likely) or the original yeast used by the Muri family was the same as the WLP351 Bavarian Weizen strain.
