Ok, so what did I do this time. I am truthful when I say that I took all precautions and it still tastes like rubber. What did I do wrong? Any tips on cleanliness and sterilization. Tried a GF blue moon, all I got is another batch that is undrinkable. Maybe a virus during fermentation or when force carbing. I did drop the rubber ring that is fixed to the handle or cap on my Corny. I did fish it out 20 seconds later. Any ideas?
