Blender said:I might be doing something wrong but when they say vorlauf until "clear", I think they mean free from grain bits and husks. My runnings are a bit cloudy but free of the bits. It takes a couple of quarts.
Sounds like you did well although if it was me I would have been sleeping by the end of the boil with the beers you put away.
I think you are right. I was not able to get it to flow without the chunks.
as for the brews, I'm not a "little guy" and I drink a lot so I'm used to it.
