Im finding that some of my beers are getting a weird taste after 2-6 weeks of age.
The problem seems its not every bottle from a batch its just like the odd one!
Early days they taste great but as they mature some are getting slightly more gassy (but not volcanic!) and are tasting slightly suspicious without being totally undrinkable.
The only error I can see is that I have been using too much sterilizer when cleaning the bottles and equipment although I have been rinsing.
Other than this Iam at a loss.
Could there be a bacteria in my fermenter?
Or is to much sterilizer the culprit?
