Bread-Bakers v103.n012.9

Does anyone know if whey is too acidic to be used as all or part of the 
liquid in bread? The representative for a New England dairy company 
recently gave an interview in which he claimed their whey could be used to 
bake bread, but didn't specify yeast or quick.

I tried it in one recipe, and it didn't rise well, though it wasn't clear 
if that was the only factor.
