Anyone else ever get a slight oily iridescent sheen on the top of wort right of the kettle? Noticed this yesterday on the top of both fermentors. All grain amber ale, pumped through counterflow chiller. No unusual ingredients, just barley malt, hops, and some Irish moss. Only source of oils I can think of is would be the possibility of grease from the pump if it has a bad seal. See picture of film. Any ideas?
