I brewed a coopers English bitter 3 months ago( my second batch at brewing it) the first batch was brilliant, a nice colour and body with a decent head and a nice taste.
With it being so nice I decided to make another batch but something has gone wrong. I made my second batch exactly the same as the first batch, everything was sanitised using milton liquid in the same way with plenty and I mean plenty of rinsing.
It was in the fermenter for 4 weeks and has been in the bottle for 8 weeks, I did a taste test before I bottled it any everything tasted the same as the first batch, so I had a bottle of it last night and it has a very strong smell and taste of iodine. Will this taste go with more bottling time or is it ruined?
I am using coopers PET bottles they have bens used a few times before so could it be that the bottles can only be used so many times.
Thanks for your help
