I poked around and got more information, including looking at some yeast
company pages and finally plowing through _English Bread and Yeast
Cookery_ which finally had the explanatory tidbit: the bottom-fermenting
yeasts (S. carlbergensis) are the ones used for light pilsners and for
lagers,which I was taught are fermented at the lower temperatures as well.
Baker's yeast is supposedly S. cerevisae.
However, I need to get a brewing book and look into the question, since
sourdough yeasts can be any one of hundreds... and I wonder how we know
that all the period ales used that stain of yeast.
