I've done about 4 AG brews on my HERMS rig and I'm loving it. My question has to do with the grain bed temp versus temperature of the recirculating liquid. My RTD sensor measures the temperature of the wort entering back into the MLT keggle after passing through my CFC/heat exchanger. If my temp sensor is measuring 159 on the wort, the middle of my grainbed is usually at 155. I'm about to do another batch soon and will have my digital thermometer to get a better and more accurate reading. So assuming that I want a mash temp of 152, do I want the temp to be the middle of the grain bed or the liquid entering the MLT? I'm assuming it's the middle of the grain bed.
I'd love to hear what your experiences are.
