Mash Notes
Mashed in all grain except roasted barley. Added roasted barley to the top of the mash tun. I had read recently in Brew Your Own that the roasted barley tends to "stick" the mash and that this technique is a brewing trick to prevent that. It is definitely flowing smoother through the RIMS.
