I normally bottle within 7-8 days but I used a different Yeast (Windsor) than the kit yeast and it took 15 days. I don't blame the fermenter, I think I have gotten something wrong with sanitising or the fact it took so long to brew that it got a germ of sort in there, maybe at dry hopping? so disappointing come bottling day and you have a little taste and all is not good... I'm don't want to blame the fermenter either. I have two smaller ones of the same type and had no issues with them at all. But it is odd that two consecutive batches in the same FV are showing signs if issues. I'll leave them in the cupboard for the next few weeks and then I'll see.

Or a non sealed lid issue. Wouldn't I see signs of an infection? Any chance it might improve if there's no oxygen left for the bacteria? Or should I tip it all out? The flat batch, I'll give more time to carbonate. Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted June 10, 2019 Share Posted June 10, 2019 If it's already like vinegar it's fecked. Sometimes they're not really visible. I had a cube get infected with it once, blew the tap out all over the laundry floor and stunk of vinegar. 1 Link to comment Share on other sites More sharing options...
Lab Cat Posted June 10, 2019 Share Posted June 10, 2019 2 hours ago, Aussiekraut said: There is almost no sediment in the bottles. I always use 1 or 2 white glass bottles, so I can see what's happening and there doesn't seem to be much viable yeast in there, if any. That suggests much lower yeast than usual - whatever the reason, time should fix that. No idea on the balsamic one... 2 Link to comment Share on other sites More sharing options...
