When using feedstock grade molasses, check ingredients very carefully. Most molasses of this type contains persevatives like proprionic acid (see my posting http://groups.yahoo.com/group/new_distillers/message/38508 ) which is very deadly to yeast.
If you find an unadulterated source, then its fine to use. ZB has used a feedstock grade made by Land O' Lakes Purina that is unaduterated and works well. See the thread "Calling all Rummies" http://groups.yahoo.com/group/Distillers/message/47056 This is the stuff ZB uses (if the picture comes out)
