| Simonaitis || [http://www.garshol.priv.no/download/farmhouse/kveik.html#kv32 16] || [[The Yeast Bay]] || Simonaitis Lithuanian Farmhouse|| Single strain isolate kindly provided by Julius Simonaitis via Lars Garshol. Across a wide temperature range this culture will throw a mix of orange, tropical fruit and stone fruit esters that is reminiscent of POG Juice (passionfruit, orange, guava), and produces distinct spicy/earthy/herbal undertones. While not a “kveik” strain, it handles high temperatures and high gravity worts well, with an upper fermentation temperature of 95ºF and a high alcohol tolerance (>10%) <ref>[https://www.theyeastbay.com/brewers-yeast-products/simonaitis-lithuanian-farmhouse-yeast Simonaitis Lithuanian Farmhouse.

===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 [http[Saccharomyces#History_of_Domestication|History of Domestication]] for more information on the beer yeast genetic groups) <ref>[https://www.garsholfrontiersin.org/articles/10.3389/fmicb.2018.02253/full A Unique ''Saccharomyces cerevisiae'' × ''Saccharomyces uvarum'' Hybrid Isolated From Norwegian Farmhouse Beer: Characterization and Reconstruction.priv Kristoffer Krogerus, Richard Preiss, Brian Gibson. 2018. DOI: https://doi.noorg/blog10.3389/406fmicb.html Full write up 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 Lars Garsholthe Muri family was the same as the WLP351 Bavarian Weizen strain.]
