Mash Notes
I barely fit the mash into the mash tun. There was about 3" to spare after letting wort into the RIMS. I stopped the underlet halfway into dough-in, to remove air space from the grain so there would be room. Maybe I could fit 26 lbs. of grains, but it would be quite tight. The RIMS worked fine with a 1.1 water/grain ratio (qts/lb).
