Apologies for reviving a zombie thread, but I don't think this information is correct, and I didn't want anyone to happen upon this thread and be misinformed.
Well, this is an old thread, so it should be expected that the info is outdated, especially since there were genomic studies conducted of various yeast strains between then and now. For what it's worth, here would be my edits of that old post:
Bry-97 = Ballantine Ale = no equivalents besides Mangrove Jack M44 West Coast which is just BRY-97 repackaged
US-05 = related but
NOT the same as BRY-96 Ballantine Beer (a.k.a. "Chico," Wyeast 1056, WLP001), higher ~83% attenuation
S-04 =
WLP006 Bedford, which is
NOT the same as Whitbread "B" (which might be either Wyeast 1098 or WLP007 but
NOT both)
W34/70 = W34/70 (a.k.a. Wyeast 2124, White Labs WLP830)
WB-06 =
WLP570 & Wyeast 1388 Belgian Golden Strong, and NOT at all related to German W68 (Wyeast 3068, White Labs WLP300)
S-189 = Samiclaus (a.k.a. White Labs WLP885) Hurlimann brewery in Switzerland
And Windsor... might not have any exact equivalents. Closest might be Fermentis S-33, or also Danstar-Lallemand's other London ESB dried strain which is very similar, and Mangrove M15 Empire which just repacks one of those other three. And Munton's old yeast is also similar but not quite the same.
For greater details on approximate equivalents for these and for every other dried yeast on the market based in part on genomic studies and thousands of hours of deep thought, see here:
