Mash Chemistry and Brewing Water Calculator

Brewed 7/20/14. Strike water was 174F and it was about 152F. Recirculated about a gallon and a half down to 150F. I added 1lb rice hulls because when recirculating it got a bit stuck. I adjusted my mill gap recently so that might be a factor. Ph reading was 5.2 which was what was supposed to be predicted. Mash was very thick and could have maybe used more water. Vorlaugh was a bit slow maybe due to a lot of grains. Sparge was under by about a half gallon so I heated a half gallon more and sparged with that. Boil OG was 1.068 which puts the kettle efficiency at 73% which is a bit low. I believe I actually had about 8.75 or 9 gal pre-boil which probably wasn't that good. Efficiency was way down again. I didn't boil off enough so maybe that is why. Had about a half gallon extra in the boil. The huge drop in efficiency might be because of that. Pitch was about 72F and I cooled it to drop it a bit more. Ended up being about 64F and fermentation. 7/21 morning, fermentation has started and is sitting at about 65F. By evening it had drifted up to 69F so I cooled it back to 66F. I also added 6oz of turbinado to kick the OG and alcohol up a bit more. 7/22 the brew heated up to about 70F by morning so I cooled it down to about 66F. Might have cooled down lower than 66F, but by night time it was at 67F. 7/23 morning the brew had heated up to 70F cooled it to 68F. Was still sitting at 68F by evening. 7/24 out of swamp today, temp about 71F. It finished fermenting at about 75F as it has been quite hot. Took a gravity reading on 8/20/14. Fermented a bit more than expected but it tastes awesome. FG is a bit lower than I wanted but we shall see how the body holds up with a bit of age and carbonation. Prolly from the extra sugar. Kegged 8/22/14. Force carbed it and bottled all of it on 2/3/15, bottle code RS3. Beer had a very nice coffee and dark chocolate notes. Very smooth and balanced with a nice body despite it fermenting down more than desired.
