Layer of dried krausen?

[gregorz]

I've left wort in primary fermenter for 6 weeks. I've opened it just before siphoning the wort into bottling bucket. Wort had something like residue of dried yeast at surface (see attached picture). The wort smelled and tasted good, so I've bottled the beer. But I would ask you to comment the residue on the surface of wort.

The layer on the side of the walls is normal, I can't comment on whats on the surface as the photo is quite low quality

Photo in is only a thumbnail - click on it, to get bigger version. Or is also the bigger version not big enough?

Ah yes

Looks OK to me from what I can see. Just yeast residue floating on top :thumb:

I always transfer to secondary because of the risk of infection. Dried on Krausan is food for airbourne bacteria and wild yeasts.

You don't want this

This was a white mould which grew on an FV of mine left for a week after fermentation.

I was lucky that it didn't infect the beer if I didn't bottle when I did and had left when you did then I would most certainly have had problems.

However looking at yours what was the scum on the surface of the beer? after 6 weeks I would have thought anything left over from fermentation would have dropped to the bottom. That would have me worried.

and for those who have difficulty in removing the dried on crust.....AFTER the wort has been transferred........use an old fashioned butter knife laid flat aong the surface. Much better than rubbing hard with a sponge or scrapper which may leave deep scratches in the plastic vessel.....

Is there anything that the old fashioned thin bladed butter knife is not good at ?

Soup? :whistle:

Just in case anyone is tempted to taste that dried on ring around the top of the fermenter.......DON'T!! I can attest to the fact it tastes thoroughly foul :sick:
