Hello... I am new to the forum and need some advice.I have only done 3 AG brews but with disappointing results.I have brewed 3 different Citra IPA's which taste ok going into primary but when I keg/bottle them they develop an unpleasant taste like a green appley/synthetic taste.I tried an extract brew kit and this also has now developed the same taste,it has been in my keg for 3 weeks.Can anyone help? could it be the water?? The only decent brew I did was a small 1 gallon AG brew in a demijohn just using pans to boil the grains.Feel like giving up altogether after all the time and effort.Hope someone has some idea of what I might be doing wrong.
