To make good beer, you have to aerate the wort well. I rock and slosh mine in my lap for a couple of minutes. This also gives me time to bond with my fermenter; tell it what it means to me; how nice it has been to me over the years, having asked for nothing in return except a good cleaning and sanitizing; most importantly, it's a chance to listen to any problems it may have. It's a wonderful --- often emotional --- moment. After a long and hearty hug, I put it downstairs, turn off the light and say, "I'll see you in three weeks." And that's how you make good beer.
