The term "landrace" should not be equated to "kveik". Kveik has been suggested to be a subtype of landrace yeast, but "kveik" is a term used specifically for Norwegian farmhouse brewing yeast and mixed cultures. More information on Norwegian kveik can be found on the [[Kveik|Kveik]] page. for more information, see also [https://www.garshol.priv.no/blog/420.html "Farmhouse yeast: what do we know?"] by Lars Marius Garshol.

| 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.

| Jovaru || [http://www.garshol.priv.no/download/farmhouse/kveik.html#kv32 32] || [[Omega Yeast Labs]] || Jovaru™ || This strain tests positive for the STA1 gene, an indicator of [[Saccharomyces#Diastatic_strains_of_Saccharomyces_cerevisiae|a diastatic strain of ''Saccharomyces cerevisiae'']]. This strain may have the ability to metabolize dextrins over time, resulting in higher than expected attenuation. JOVARU™ is an ALDONA UDRIENĖ™ yeast strain that originates from the famous JOVARU™ Brewery that has been in operation since the mid-19th century <ref>[https://omegayeast.com/yeast/lithuanian-ales/jovaru-lithuanian-farmhouse Jovaru Lithuanian Farmhouse Yeast. Omeaga Yeast Labs website. Retrieved 05/16/2019.]</ref>. A portion of the revenue from this culture is given to Aldona Udriene.
