Describe the wonky fermentation.

[robbarwell]

For wonky...

The 2 fermentations did the same thing...

Set off beautifully, then at the end of the fermentation whilst crash cooling, they both formed a dusty skin on the top of the beer. Then would not clear (or stop fermenting) and left a strange chemically twang to the beer. This twang got more and more, to a point that it was undrinkable. The first time it happened, I put it down to an infection (this was on the big 5BBl kit)...then it happened on the small 1/2Bbl kit..But, It was all fermented from the same packet of yeast (500gms). I had previously used BRY97 on a brewers gold brew on little kit and it was simply glorious.

I have an unopened block of yeast (500gms) and was planning to bin it...but for the sake of the cost of a few hops and malt, I want to give it one last razz
