Amazing, Every time I read an article, I learn something. Never though about heating the
first runnings to counteract the cooling. Can't remember if you add boiling water to
reach mashout?
The most important thing to do is to make beer and keep records. Simple things you
observe today are quickly forgoton tomorrow. The best thing I observed with my setup is
the ratio of grist to water. After tweaking it a bit to compensate for the mass of the
cold SS kettle, I add Q1 volume of water at temperature T1 resulting in a mixed mash
temperature of T2. I am not trying to get overly scientific. Trial and error helped me
adjust the additions and currently, I modify inlet temperature just a few degrees for a
few degree swing in mash temp.
Keep brewing, keep it clean, keep good records and push the limits. Remember, at homebrew
levels, a bad batch of beer likely costs less than a quarter the cost of a good meal at a
nice resturant.
