Ok, so I tried to do a Sculpin clone from a recipe I grabbed from HBA. I'm just breaking in a HERMS system & this is my first all-grain attempt. I way undershot my gravity, ending at 1.043 when my target was 1.067.
I held my mash at 148-150 for 1 hour. There are a couple little things that I wasn't sure of. I didn't know how much sparge water I should have used, but I used my refractometer to periodically check what gravity levels were coming out at. I stopped sparging when I started to get a gravity of 1.015.
Another thing I wasn't sure of was how to check to be sure that I had fully converted. I knew of the Iodine test, but didn't have any iodine. Is it possible that I undershot because I hadn't fully converted yet? is there a way I can test for conversion with my refractometer instead of using Iodine? Another thing I thought might have been a culprit was the fact that I left about 1 & 1/2 gallons in my brewkettle. Maybe I used too much water for sparging. I filled my Mashtun until the water reached the false bottom, then I added 1.5 quarts per lbs grain. Now that I've undershot by so many points, what can I expect? Just a more watered down beer? I'm considering another brewday tomorrow...
