Well I am still so new to all grain, and beer making period for that matter, that the software is somewhat still kind of confusing. I used the trial beersmith to calculate all of my strike temp to get my grains to 155F.
I also used the water needed under tools to get my total water amt. I did not however know my total dead space in the tun, and did not account for that so I came up at the end at 1.060 instead of 1.050. I just added top off to make up for this.
I am for sure going to take 1st runnings, and then sparge with additional water. I noticed some people break up the 2nd sparge into 2 batches, even at different temps sometimes . Is this for any reason other than trying to stay withing the 170 bracket?
