Denny, what's the gap on your mill?I woefully undershot my target pre-boil gravity today, first time being careful to try and collect data with the new cooler tun. I'm hoping all I need to do is crush finer.
I think Denny can be quoted as saying, "crush until you're scared."

The experiment was meant to test whether skipping vorlauf causes astringency (there was no difference). Effect on clarity was unexpected.Wort:Beer: http://brulosophy.com/2016/02/22/the-vorlauf-effect-pt-1-does-it-make-a-difference-exbeeriment-results/"the non-vorlauf batch was left alone while the other batch had approximately 9 gallons of sweet wort pulled from the bottom of the tun and gently placed back on top of the mash."I think the most I've ever used for a vorlauf is about 1 gallon. 9 gallons seems very unusual.

I have admit that I found that particular experiment questionable. Those two beers in the photo I posted had been lagered and fined, yet they're both still opaque. Clearly some problems with technique.
I have no idea...I've never measured it because i don't care. I'm making grist, not gaps, and I adjust by what the grist looks like. I just closed the rollers on my JSP adjustable as far as they would go, then opened it a hair until I just saw them move.
FYI, I just tried that gap setting method with my monster mill 3.Damn near broke my wrist trying to hold the drill when the whole thing locked up. Evidently that's not the approach to take on my system.Maybe I should have been more scared.
