Hi All, After a period of getting the brewhouse together with Fermentrack/iSpindel/fermentation fridge, kettle, fermentor, odds and ends I finally had the first AG brew day on Friday. Think it went well, fairly close to numbers I think? - Pre boil was 1.047 and expected 1.046 and OG was 1.057 and I got 1.054. Used beersmith having setup my equipment prior to the brewday, BIAB (Crown), 40L, 7kg, 012 specific heat, with a brewhouse efficiency of 72% etc. A couple of points I noticed during the day. 1) after adding in the required 33.57L of water, after the mash and raising the bag, I had 1 extra litre in the kettle than brewsmith estimated post mash (estimated 30L, I had 31L). Yes i did squeeze the bag. What and where do I need to update this within beersmith for future brews so it becomes more accurate? 2) Estimated post boil was 25.5L and I ended up with this amount. If 1) above gets changed, what do I need to change here? I think I have since upped the boil off rate to 5.5L, from 4.5L on my equipment profile already. 3) I was supposed to get 22L of wort in the fermentor, ended up with 21L. I had 4L of trub that didnt whirlpool no matter how hard I tried. This 4L of trub was set as per the equipment profile. Do I need to account for this 1L somewhere also? Cheers!
