scum line, Wyeast 1098

[Fraoch]

I bottled a pale ale some 2 months back and have noticed a scum line around the neck of the bottles where the top of the beer is. I opened a couple to check that the beer is still sound and - hic! - it is.This is the 4th time ive used this batch of yeast and use the distilled water method of washing as described on this website.Fermentation and everything went well,its just since bottling. Anything to worry about??

Yep, I'm going with trub made it into the bottle in a fine form. Do that tall cylinder thing to fine that stuff out.
