I just built a two tier system that is something like a counter top Brutus 20. I am planning on recirculating during the mash but to date have not yet done that. My concern is vorlaufing. I am using a collapsible steamer as my false bottom and at times it seems like no matter how long I let it run off, I still get a small amount of particulate in the boil kettle after the mash.
I can't see this until after I drain the boil kettle though and I am wondering if this could be leading to my astringency in my beers. It doesn't appear to be a whole lot of volume of husks, maybe a couple tablespoons as most. Is this enough to cause a problem in a 2.5gallon batch?
My other suspect is my water. I have since tried a different water source but haven't had either analyzed for content. I think my next brew I will build the water but want to try and eliminate some variables from the equation before I started chasing my tail.
Thanks in advance for you help!
