====''Saccharomyces cerevisiae'' var ''boulardii''====
Although originally designed as a separate species (''S. boulardii''), it is actually a variety of ''S. cerevisiae'' and shares more than 99% of the genetic makeup of ''S cerevisiae'' <ref>[https://en.wikipedia.org/wiki/Saccharomyces_boulardii ''Saccharomyces boulardii''. Wikipedia. Retrieved 12/07/2017.]</ref>. This strain is sold by [[East Coast Yeast]] in their ECY03 Farmhouse Blend and [[Bootleg Biology]] as their "Chardonnay" strain <ref>[https://bootlegbiology.com/product/chardonnay "Chardonnay (S. cerevisiae boulardii)".

===''S. jurei===
Newly discovered ''S. jurei'' was screened for use in beer, as well as hybrids between two strains of ''S. jurei'' and two strains of ''S. cerevisiae'' (Omega Labs OYL200 "Tropical IPA" and OYL500 Saisonstein). The hybrids were non-GMO type hybrids (natural mating). As expected, the hybrids were better at fermentation in wort (better utilization of maltose and maltotriose). The hybrids were reported to be "tropical and floral" from esters characterized by a combination of both parents, and one of the hybrids appears to have lost the ability to produce phenols (4-vinyl guaiacol; clove) from the ''S. jurei'' parent <ref></ref>.
