How do I create a custom mash profile? I need to create a mash profile that uses a single infusion to 152* the followed by a deconcoction mash to 168* in order to preform the mash out. The problem I am having is that the volume of the mash does not allow additional water to be added. I am brewing Northern Brewers 115th Hopburst Dream. I have 18 pounds of grain in a 10 gallon mas ton
