Yesterday I began work on only my second brew - a DFH 90 min all grain. The recipe called for an estimated OG of 1.075-1.090. I struggled a little with the mash temperature and it took me about ½ hour to get the temperature right. Once I did I let it sit for about 40 min after reaching that temp (probably not long enough?). I sparged and got my boil kettle to 6.5 gallons (thats all it would hold) and everything else went good, but I boiled off a lot of wort over a 105 min boil and I ended up with just over four gallons 4 gallons. I will note that it took a long time to achieve a boil.
Before transferring to the fermenter I took a hydrometer reading and got 1.06. I then transferred to the primary, added almost 1 gallon of water to get to 5 gallons and pitched the yeast. Shook it all up nicely and took another hydromerter reading and this one came in woefully low at 1.04. This morning I looked at the fermenter and it looked like the contents were boiling there was so much activity. The airlock didnt pop off, but krausen did escape and splattered the wall. That seems to have receded a bit so no big time blow off hose is necessary at this point.
That all said, it looks like I messed up and did not get good extraction. I want to raise the gravity and was wondering how I would do it and at what point in the process I should do it. As always, thanks in advance for all the help.
