There is an article floating around the Internet where Mike Carpenter mentioned that Anchor used whatever strain they could beg, borrow, or steal before they acquired the strain that they use today from Wallerstein.
With that said, I have a culture in my bank that was used at the old ACME Brewing Company in San Francisco (
http://brewerygems.com/acme.htm). I dug it out of the UC Davis Culture Collection. The culture was deposited in 1942. ACME survived prohibition; therefore, it is more than likely one of their original brewing strains. As ACME was founded by the same person who founded Olympia, the strain may have been brought to San Francisco from Tumwater. What I do know about the strain is that it is typed as Saccharomyces cerevisiae, and it is a diploid (2 x 16 chromosomes), which is a unique attribute when it comes to brewing strains. Most brewing strains are polyploids (more than 2x16 chromosomes). Bry 96 (a.k.a. Ballantine "beer," "Chico," Wy1056, WLP001, US-05 ...) is also a diploid, which is why it is such a unique brewing strain. The difference between Bry 96 and the ACME strain is that the ACME strain is highly flocculent, and it produces just enough sulfur to make a convincing lager at 16C. I mentioned this strain to Chris White at NHC. Hopefully, he has looked into evaluating it for inclusion in the White Labs collection.
