I brewed a porter on Feb 27th. I hit my target gravity spot on (1.052). I chilled my wort to 68 degrees and pitched two packets of Safale S-04 directly to the wort. I could not keep an airlock on after two hours, had to use a blow off. Within 7 days, I had reached 1.012. I racked to a secondary for a couple of days and cold crashed after the gravity did not change. Friday, I kegged and force carbed. Taste my beer last night and it was really boring. It smells awesome, slightly spicy and quite roasty. But, it has very little mouthfeel and little malt complexity. Could over piyching be the cause?
