I know it's the same yeast, but they are different strains and all have different levels of attenuation. I don't want to kick off a secondary fermentation in the beer, although now that I'm talking this through, if I do the beer first, it can't get infected with the wine yeast, and the wine won't get infected by the beer yeast (its already attenuated past what the beer strain can handle). Now I guess it's just the bread yeast I've got to worry about. It's not the bread baking I'm worried about, it's the open starters in the kitchen that I can smell that could pose a problem.
