Manufacturer's don't "make" new strains. They either acquire a sample from elsewhere, make a master slant, and then propagate (WL001/WY1056 are the same "Chico" strain from the same brewery) or find/develop a mutant from an already existing strain. The mutant strain then has to be developed further through stressing/coaxing to make sure that it is a stable mutant with consistent expression of the desired trait. It is possible to do this at home (Cry Havoc) but the chances of coming up with a stable mutant outside of laboratory conditions is not very likely unless you are willing to invest a lot of time and money.
If you really want to get into some reading on it check out this review:

Custom strain...custom blend...all the same to me. I try to make my answers in this site as simple as possible since most homebrewers aren't biology majors.

I have never heard of anybody using a beer specific strain of yeast for baking but it would make sense since bakers and brewers yeast are both S. cerivisiae, however I do know of a lady who has been making mead and other honey/fruit wines with Fleischmann's for over a decade and is constantly winning awards for her entries. Personally I think it would be kinda cool to use part of a fresh yeast cake to get some dough rising and make some tasty bread.

Glad you mentioned the Fleischmann's... My supplier forgot the yeast when she put my ingrediants together and they closed before I started the boil... Let's see how it goes!

The problem with using Fleischmann's is the amounts of contamination units allowed per package. I don't know what the standard is but I know when testing beer and yeast slurries labs aim for less than 10 colony forming units with 0 preferred. Fleishmanns is cheap because they do not adhere to strict cleanliness standards like brewing yeast producers because baking yeast is made for baking and any contaminates die in the baking process.

Good luck with the Fleischmann's. It will ferment but it will be slow. And the taste will not be right. I did it many many years ago and I learned bread yeast is better for bread. And yeast for beer is better for beer. And there is no real difference in cost.

Taste is ok, won't be using this recipie often for other reasons. Biggest pain about Fleishmans is the low floccuation. I lose about an ounce or two each bottle trying to avoid the dregs. Very carbonated, but could be the recipie too.

Worst case scenario: its better than dumping a batch, but I bought extra beer yeast for the next time I'm in a bind.

I tried it. Bread came out very dense.
