So last night I made a brown ale, checked on it early this morning and the Krausen was just starting to form, however it looked liked there was a bunching of yeast in part of the Krausen. Got back this afternoon and there seems to be this brown gunk in the Krausen as it rises. Here is a link to the pics http://www.flickr.com/photos/42486286@N00/. Is this an infection.
