I was hesitant at first to add another step, but pre-boiling really doesn't add all that much time as long as you have a decent chiller. At this point it seems easier to me than attempting any alternate methods of water deoxygenation (yeast + sugar scavenging, for example).
I'm such a dunce I never thought to chill the water after the preboil...
I tried the yeast method on Sunday. We'll see how that works.
I have to say, I have much better foam then ever before. Beers are very good, but it's all subjective. The foam however has been outstanding.
I don't know that I'm doing it all right, but I believe there is something there.
