So, the last couple all-grain batches I’ve done have been batch sparge as opposed to fly sparge. I only brought my sparge water to 170 degrees. What I now realize I didn’t account for was the fact that the grain bed lost quite a bit of temperature during the first drain. So, with this new information I heated my sparge water to 180 and when I added it to the grain bed ended up with a temp of 168 degrees. So, this will be the new sparge temp that I aim for. Also, with beersmith I tried the equal runnings options and hit the target pre-boil gravity exactly as expected. Way cool
