I'm wondering what you who use coolers do in regards to pre heating your coolers before you actually add the grain/strike water.
I've seen some info where people bring a gallon of water to a boil and add that in, the drain it after a half hour or so...others just heat their strike water higher than strike temp and let it cool to whatever a strike water calculator tells them their temp should be, then add the grain.
Others still heat up 5 gallons of water to 170, put that in the cooler, then drain that after 30 minutes...
What do you all do?
