Ok, I am really discouraged. I've brewed this twice and had the same issue both times. So I brewed this in early Aug, after 3 weeks cracked my FastFerment Conical and saw a white sludge all over the top. I thought my first infection. I still ended up kegging it, leaving the top inch or so of the sludge still in the conical.
I had taken a picture of the sludge and took the picture to my LHBS and showed it to the owner. He said not to panic, it just looks like some mold on top. He gave me a glass carboy to take home and said to move the beer into the carboy put it in a dark place and see if it happens again. If not it is good. When I cracked the keg open to transfer, it was very clean on top. So I tasted it, tasted fine so I decided to leave it in the keg. In the meantime, I had already bought all the ingredients to make again.
I did not make it again, instead I made a Pumkin Ale, which turned out just fine, no problems. So with the ingredients to make this again I went ahead and brewed this a second time. Well I cracked it open this morning after 3 weeks to check on it, and damn it, I have the white sludge again. See picture below.
I've never brewed with Malto-Dextrine or Lactose before this recipe, is this a result of that? Any help or advice would be appreciated.
