Hi all, I brewed my second batch on my 6.5 Anvil Foundry today and copied Clawhammer's Candy Orange IPA recipe (Candy Orange IPA - Hazy Session). I am still dialing my Brewfather numbers in but today I found something strange with my SG and OG. Their recipe targets an OG of 1.046, I set my Brewfather recipe for a mash efficiency of 70% and an OG of 1.048 with a pre-boil gravity anticipated for 1.04. I mashed and sparged and collected a sample of wort to measure my pre-boil gravity and it was bang on 1.04. I remembered the temperature correction and measured the sample wort temp as 130 degrees F (it had cooled a bit in my graduated cylinder), making the pre-boil gravity 1.052 after correction. Obviously this is a huge overshot but I was also ecstatic that my actual mash efficiency was 89% and not 70%. I continued with the boil and did not add water to dilute my pre-boil gravity reading. I finished and moved on to the hopstand step, where in addition to hops some simple syrup is added. After cooling to 70 degrees F, I measured my OG and it was still at 1.052. What are some possible reasons my SG and OG readings would have been the same? Is the temperature correction really inaccurate? I've double-checked the calibration of my hydrometer and that wasn't the issue.
