I recently brewed a 13.5 gal batch of extract RIS (Home Brew Club Style for AHA). I think I may have pitched to much yeast. My air-lock blew off my fermenter. Luckily I saw the cap bulging and I had blow off tube sanitized and ready. My temp didn't get to high, I didn't smell any esters coming off the blow off tube. Will over-pitching effect my beer?
