Just made my second batch using an Anvil Foundry all-in-one brewing system. I used an immersion chiller to bring the wort down, but could only get it down to 82F (groundwater in Texas in August... whatya gonna do?). I didn't want to pitch my yeast at >80F, so I decided to seal it up and leave it overnight to cool to room temperature.
This morning, I decided to use the pump that came with the Anvil to pump the wort to the fermenter. I realized this would leave a significant amount of sediment in the Anvil, but figured it would have settled in the fermenter within a few hours anyway. But then I took my gravity reading and I'm .010 lower than my target. Would this be normal/expected?
Since the fix for low OG is to add DME - which is simply adding more particulates - do I need to be concerned? Do I need to go ahead and add DME? I guess it's a matter of if the DME stays in suspension. Is missing by .010 "significant"?
I'm still dialing in the adjustments I have to make for the Anvil, so it could be that I didn't use the right amount of water during the mash, or my sparging technique isn't effective.
