The homebrew digest had a recent thread on this subject. Without
cutting and pasting from that forum, what I took away from reading the
discussion was that all yeasts are 'designed' for their environments.
Bread yeast creates glutens,

No, it doesn't. Gluten comes from wheat. Not yeast.

Since CO2 and ethanol are the byproducts of *all* yeast metabolism, it's
difficult to see how the production of either one would depend on the strain
of yeast used.

temperature range, amongst other qualities. Wine/beer yeast has similar
but different qualities, and is not as specialized for those tasks which
make a good bread yeast.

Higher temperature range is certainly an important characteristic for bread
yeast. Certainly bread dough will rise if made using wine yeast, but I
wouldn't expect it to rise nearly as much as it normally would, due to the
lower temperature tolerance of wine yeasts. Why bother, anyway? Wine yeast is
*much* more expensive than bread yeast, and undoubtedly will not do a better
job.
