G'day All. I just racked my latest brew, a "half-toucan" Bavarian Lager. One can Coopers B L , 500gm of LDME and a teabag of Hallertau for aroma. ( made up to about 12 litres )

I noticed a few small patches of pale tan/fawn coloured stuff floating on the surface. When I skimmed some of it off, it seemed to be very fine powdery material - very similar to the yeast, but a little darker in colour. I tasted it and found it intensely bitter. I left a fair bit of liquid in the primary to minimise the amount of the stuff getting into the secondary, but if it is an infection, I know that won't save it.

The beer from the tap tasted a little bitter, but for a raw beer it seemed OK. If I hadn't seen the stuff floating on the surface, I would not have thought there was any problem. I suspect it's some kind of infection, but what ?? Anyone know, or got some idea ??.

I need to know, so I can work out how to eliminate it from any future brews. I was very thorough with sanitation before it was made up, I used a starter for the yeast, and the airlock was bubbling 4-5 hours . There was no delay between mixing and pitching, because the top-up water was cold enough to bring the temp down immediately.

My best guess is that it must have been airborne, or in the top-up water, because I believe ( well I'm as sure as one can ever be in this game ) that my equipment and ingredients were O.K.

Here's hoping someone can help.

Thanks, Deegee.
 
Your brew is fine - just never taste the brown sludgey stuff in future and you won't worry (or be sick)
 
Hey Deegee,

yes that stuff is bitter it is very normal! i believe it is yeast byproducts.

just try not to disturb your fermenter to much otherwise those bits will fall off into your brew

and stop poking and prodding around your brew will be fine!

Thanks for the prompt replies, and the reassurng advice guys. I had hoped that might be the case, but I also thought that maybe I was just being optomistic rather than realistic.

I have always noticed the brown ring around the top of the fermenter, and I seem to remember reading somewhere that it is made up of bad tasting gunk, but I have never noticed it floating on the surface like this one.
I remember once having a white film on the surface of a brew, and that was bad news.
Anyway, I have racked it and will leave it to finish fermenting, and then chill it to settle out the suspended stuff before I bottle it.

Cheers, Deegee.
