You all have been SUPER helpful in the past and I'm probably concerned over nothing, but I figure I'll bring it to you the experienced brewers for thoughts.
Here's the timeline of the beer:
-My 3rd batch, first two went smoothly and exactly as expected despite a bit of difficulty with temp control.
-This beer is the Coopers Irish stout kit, done with 1kg of DME and a bit of dextrose to bring the SG to 1.05 (I can't find my notes anywhere so I'm working off memory here). Yeast was the included stout yeast.
-I started the kit, after a week I check the SG and it had only moved ~10 points or so, I was concerned it stalled so I repitched with the only yeast I had around, a standard coopers ale yeast.
-Life got in the way and the beer sat in the primary bucket in a swamp cooler (water only, no ice) for ~2 months. I went to bottle tonight and I found a layer of scum on top of the beer I've never seen before. Looked like yeast cake, quite hearty in meat and body and fairly thin.
-Taking Revvy's and everyone else's advice into account I tasted it and it tasted fine (in fact pretty good!), but there were all these floaties in it that were pretty gross for mouth feel wise
-Rather than bottle it ask risk bombs when I have to leave home for a month, I just racked it to a secondary and came this way for advice. As I racked it I noticed a lot of the same scum was built up on the side of the bucket as well.
Sadly I didn't take any pictures of the top scum but the attached pictures of the remnants are a little concerning to me. Yes I know any concern is probably over reacting, but I'd rather be a bit cautious than deal with flying glass everywhere :P
Thanks in advance guys for any thoughts you might have on what this stuff is. (my main thought right now is over pitched yeast from the "stalled" ferment)
