The wheat ale did ferment down to about 1.020. It had a sulfur smell to it, but tasted like a normal wheat ale. However, now there is some skin on the top. If this is bacteria or mold, is there still hope? It is presently in a fermenting bucket. When I transfer to secondary or bottling bucket, if I draw off all the wort being careful not to disturb the skin, will it be ok? I brewed 2 batches at the same time, and the other one went off without a hitch. Since the other batch is good, I don't really think it is sanitation problems.
