I went to pop the cork on the last bottle of my first wine, a
concord/niagra Welchs and strawberry wine, and found quite a bit of
stuff floating.

This stuff didnt show up in any of the other bottles which went down
fine altough a little green in the beginning. It looks like a flaky,
dark substance of varying size. The best way I could describe it is it
looks like shredded nori(seaweed sheets) floating in water. Dont know
how many will know what that looks like, but I feed my Naso Tang nori
on a daily basis and when he tears into the nori and it starts to
disintegrate it looks just like this.

I'm quite certain I didnt rack this stuff into the bottle, the bottles
were all somewhat light and clear after bottling.

Any ideas? Thanks.
