A few months back I made a 5 gallon batch of Belgian IPA, and unfortunately it has the dreaded band-aid aroma... and it's bad. Crazy thing is that when I transferred it to the secondary after 10 days in the primary, I tasted it and thought it tasted amazing. I bottled about 4 weeks after putting it in the 2ndary, and at that time it had a bad band-aid smell. I've used tap water from Union, NJ with all the beers I've made here in the last year, and this is the 1st to ever be contaminated with chlorine. I use One-Step as my cleanser/sanitizer as I always have, so my only explanation for the chlorine being present is from the water on that day. I would like to take a sample of my tap water and send it somewhere to be tested for levels of chemicals, minerals, etc... but am not sure where to send it. I'm also wondering if anyone knows how long it takes for chlorine to create this odor.
