I brewed an Oatmeal stout about 3 weeks ago. I used rinsed yeast (British Ale) and ferm started in about 5 hours. The beer frem'd out in about 3 days but I left it in the primary for 2 weeks to clear and clean up. The fg was high 1.023. I racked to the 2nd and its been there for a week. today I noticed a dry milky color film over the surface and it seems to be heading up the sides of the carboy (just under an inch tall, crawling up from the beer surface). I can tell the film is dry because there are a few bubbles dried in it so its held their shape. I have been brewing for years and have become very sanitary, doesn't mean it cant happen I suppose, I was just surprised. anyone dealt with this before?
