OK, I must have had too many homebrews when I made my last beer, because I have NO idea where I got my sparge water temps. Now I am getting ready to brew again, and want to figure out what temp I need to get water to, to make it raise grain bed temp to 170º. I KNOW there had to have been some online calculator I used, because we hit our 170º bed temp right on, with a double batch sparge. First half of water was 180-something, second was around 176º I think... someone help me before I totally loose ALL of my mind.
Brew365 does rock, and that is what I use to figure water volumes and strike temp. They do not have a calculator to figure sparge water temp though. Let's say my grain bed is 153º and I need to get it to 170º - heat up my sparge water to 185ºish?
I just know there was a site that figured this out exactly... but I did not bookmark it. Once again... too many homebrews.
That's a hard one. I use BeerSmith and still can't get the thing to calculate going from Mash Temp to 170 for my sparge. I'd also like to find a good calculator for this. Especially one that also factors in the transfer loss - (i.e. the heat loss moving the water from the kettle to a pitcher to a MLT).
