i finally contaminated a beer. my seventh beer (banana bread ale) has a pronounced rubbery character. This beer fermented like crazy, my first beer that needed a blow off tube. I used a better bottle with a rubber stopper and a 1/2 inch tube connected to it. The rubber defect tastes exactly how the stopper smelt. do you think when i add the cinnamon and vanilla and almond extracts it will cover up the defect?
