===Rimaand Marina===Two strains of landrace farmhouse yeast cultures from Chuvashia, Russia were analyzed by Richard Preiss of [[Escarpment Laboratories]] referred to by the family names "Rima" and "Marina" (see this [https://twitter.com/larsga/status/889136705571356673 tweet] and [https://twitter.com/larsga/status/887938191721988096 this tweet] by Lars Marius Garshol pending a write up , and the full [http://www.garshol.priv.no/blog/399.html blog post by Lars]). The lab performed ITS sequencing, PCR fingerprinting, and mini 7 day ferments with these strains. Unlike kveik, all of the ''S. cerevisiae'' strains were POF+ (phenol producers).

===Marinacontained what appears to be three closely related ''S. cerevisiae'' strains. They all showed pretty low attenuation after one week, but subsequent fermentations can be carried out longer. The flavors were described as "pretty neutral". There is a fourth yeast strain in the Marina that has yet to be identified <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/1800586383302901/?comment_id=2288654764496058&comment_tracking==%7B%22tn%22%3A%22R%22%7D Richard Preiss.
