Here's my situation and would like some advice to refine technique. I use a 2-gal Coleman beverage cooler to perform my mini mashes with (generally) 4lbs of grain. I preheat the cooler with near-boiling water while I am getting water up to temp for the mash to negate the thermal effect of the insulation and plastic. Now... to hit a grain bed temp as close as I can to my desired/predicted... I need to accommodate bringing the grain up to temp with the hot water rather acutely. From Palmer we've learned that...
Tw = (.2/R)(T2 T1) + T2
Tw: The required strike water temperature
R: The ratio of water to grain (qts/lb)
T1: The initial temperature of the mash
T2: The target temperature of the mash
Using this equation just seems to usually leave my grain bed a little too high. And I'm hoping that some of you may have some suggestions.
Cheers!
