Hi folks. I trying to calculate the temperature of the mash water befor mixing, aiming for 65 deg. C. I am using the Infusion calculator in BeerSmith. The only thing I wounder about is the Mash tun weight. I have read this is the weight of my empty mash tun. I am using a big plastic beach cooler. The calculated deg.C of the water changes very much if I do small adjustments here. Why is that? What does the weigth of the tun have to do with the temperature? Type of plastic, or space I would understand, but not the weight. Anyone?
Can it be that a steel tun will steal heat according to weight? More steel, more heat loss? What shall I put in the when using plastic, with very little heat loss?
