First time doing an all-grain brew with my new mash tun (one of the 10 gallon Gatorade coolers with a spigot/filter installed at the bottom). I'm doing a Gose, with 3.5 lbs each of wheat and pilsner, with a target OG of 1.035.
After getting my 2.5 gallons of mash water up to ~160, I put it into the container, dumped the grains on top of it, and let it sit for 60 minutes. Took 5 gallons of sparge water to ~145 (the recommended mash temp for the recipe, figuring that the grains and the tun were already hot), let them sit for 15 minutes on the grains, and collected everything in a 6.5 gallon fermenter bucket I had sanitized for the purpose.
I think I made a pair of mistakes, since my gravity read out at 1.014:
* I probably should have had considerably hotter sparge water
* My efficiency numbers must have been off; I was targeting ~5.7 gallons of pre-boil volume, and I cut off my mash tun after coming back in the room and seeing that I had ~6.5 gallons of wort.
After dumping some of it to get it to even fit in my boil kettle, and getting to a brief rolling boil (all that's necessary for the recipe), I've got ~5-5.5 gallons of super low-gravity wort.
Is it even possible to make a sufficiently high-gravity follow-on wort to bring what I just made back up to my target of 1.035? If so, can anyone help with the calculations for how much grain and water I should use to do so, or point me at a calculator that would help?
