''Saccharomyces cerevisiae'' is the type species of the genus ''Saccharomyces'', although ''Saccharomyces paradoxus'', ''S. cerevisiae's'' closest relative, is likely older and more globally ubiquitous than ''S. cerevisiae''. <ref>ref needed</ref> Many previously recognized species of Saccharomyces have been consolidated or reassigned to another genus, commonly ''Zygosaccharomyces''. Species of ''Saccharomyces'' other than ''S. cerevisiae'' (and only certain strains of ''S. cerevisiae'') are generally unable to efficiently ferment maltotriose, although some can ferment maltose (such as ''S. eubayanus'') <ref>[https://onlinelibrary.wiley.com/doi/10.1002/yea.3380 Bioprospecting for brewers: Exploiting natural diversity for naturally diverse beers.
