My beersmith brew sheet printout gives me some gravity numbers that I can't make head or tail of:
How can the pre-boil gravity (when I haven't added 57% of the malt yet) be 1,084, while the post-boil gravity is only 1,048? Has it added the top-up water to the bottom calculation, or something?
I've now brewed this beer. The measured pre-boil gravity was 1.023. I did not remember to measure the post-boil gravity, but after adding 10 l of water and 1,8 l of starter, the measured OG was 1.046 and the batch volume was 22,5 l.
