60 minute mash @ 155°F @ 1.25 Quarts/Pound
Brew Day 3/14/2015
Brewed by myself, which made everything a bit more difficult, but overall it went great. I put the rolled oats on a non-stick pan and into the oven at 325°F for about 20 minutes. This cook time was all by feel. I probably could have roasted them a bit more to get a darker color. But I was happy with the results after 20 minute.
I added the 2lbs of rolled oats to the 13 lbs of grain; mashed with the entire 15 lbs. I struggled with the mash considering the 15lbs of grain - I used the 5 gal Orange Coleman cooler which was maxed out during the mash. Targeting 1.25 Quarts/Pound required 18.75 Quarts of water at 169.4°F to be added to the grain.
I overshot the 155°F rest temperature by about 5°F degrees so I added ice to drop it down a few degrees. I think that the raised temperature of the rolled oats affected my rest temperature overshoot. I never used the ice trick before so I learned from my mistakes. I added too much ice and undershot by about 5 degrees. So with my mash temp at about 145°F I needed to raise it back up but I didn't have any room in the cooler. So I had to scoop about a gallon of the mash out of the 5 gallon cooler and put it into a 1.5 gallon cooler. I then added boiling water to the 5 gallon cooler and brought the mash up to the desired 155°F rest temp. It took a bit of stirring to get it at the 155°F, but once it was there, I capped the cooler and let it sit for the 60 minutes. I checked it every 15 minutes to ensure I was still at the desired temperature.
For the 1.5 gallon cooler, it had mostly water in it, but some grain too. I had to commit to doing a partial mash for that guy and get what I could out of it. I was able to add about .5 gal of boiling water until the little cooler was topped off. At that point, the baby mash temperature was hovering around 145°F - a little low, but I wasn't sweating it too much cause the larger mash was settled in at the desired temperature.
Starch conversion test with Iodine at 60 minutes was beautiful from the main mash. The little mash didn't have as good of a reading, but overall I was happy with the result. I drained the main mash into 5 gallon bucket. As there was enough room in main mash, I poured the little mash into the main mash. After the grain bed settled a good bit, I began fly sparging with 170°F water. I was able to collect 7 gallons before I began the boil. I had 2 gallons of extra sparge water that I dumped into the mash to collect second runnings. I was able to collect 2 gallons of ~1.020 second runnings.Pre-boil gravity reading was 1.054 SG! I was very happy with this as it is 70% efficient!
