I'm planning to do my first batch sparge, and I haven't been able to find any formula to use to figure out what the temperature of the sparge water needs to be.
I know that the temperature of the water, once I've added it to the grist, should be about 168 degrees. But the grist is not going to start out at that temperature, since my mash is going to occur at 151 degrees (I'm not doing a mash-out). So after I drain the mash water, the wet grist is probably going to be somewhere around 145 degrees, I'm guessing. Anyway, my sparge water is going to have to be at a higher temperature than 168 in order to bring the grist + sparge water temperature up to 168.
I was hoping to find a formula that would take as parameters the temperature of the grist, pounds of wet grist, and the amount of sparge water, and tell me the required temperature of the sparge water to reach 168 degrees in the mash tun.
Anyone know of such a calculation? I'm looking for a mathematical formula that I could create in Excel, rather than a black-box calculator such as the one on beertools.com.
Thanks,
Shaun
