Looking for information on the origin of the Coopers ale and lager yeasts.
The Ale yeast has been claimed to be Mauribrew Ale Yeast 514 though some are fiercely opposed to the idea.
The Mauribrew brand seems to have Ale, Lager, Draught and Weiss style yeasts. (See screenshot below.)
The AB Mauri and AB Biotek websites offer no information about the Mauribrew brand.
Coopers indicates that their Original series yeast is "our own strain, not the same as the yeast in our commercial ales, developed in-house and propagated under contract".
Coopers also indicates that the International and Thomas Coopers series yeast - "these strains are commercially available dry yeast and their details are held in confidence".
Is anyone aware of DNA sequence matching (is that the correct terminology?) that has been done on these yeasts?

I'm not aware of any public sequences of Mauribrew strains. This comment by "notmyrealname" is the most plausible version I've seen for the complex tale of Cooper yeasts but I have little independent information on the matter, other than a "Cooper" yeast of some kind is sequenced and is a close outlier of the main British group :
