In general, most of the cultures of kveik that have been analyzed contain more than one strain of ''S. cerevisiae'', which was the only species in all of the kveik cultures analyzed by Escarpment Laboratories except for the Muri kveik. The Muri kveik contains a single isolate of what appears to be a domestic (human produced) hybrid between ''S. cerevisiae'', ''S. eubayanus'', and ''S. uvarum''. Genetically, kveik yeast form their own group of closely related domesticated ale strains that do not closely match the "Beer 1" and "Beer 2" yeasts from the [http://www.cell.com/cell/fulltext/S0092-8674(16)31071-6 Gillons/White Labs (2016)] study that sequenced previously known ale strains (see [http://www.garshol.priv.no/blog/374.html "A family tree for brewer's yeast" by Lars Marius Garshol]). The closest related domesticated strains were WY1318 London Ale III™, WY2565 Kölsch™, and WY1007 German Ale™ <ref name="Tyrawa_2017" />.
