Good afternoon-

I am racking my Muscats and when I siphoned one off (get the mouthful)
it had an aftertaste- I'm reminded of when my wife cooked Cod in the
microwave.

It's rather fishy tasting, the best I can describe it.

I found this page when searching for fish smells-
http://www.honeycreek.us/winefaults.htm
and it faults Butyric acid bacteria infection.

1) Is there a way to stop this ? (SO2).
2) Anyway to clean it up?

3) Where the **** did I get it from....

Thanks in advance-

Jason
