I am a little confused. I am very new to AG brewing. My first batch was an American IPA with a target OG of 1.062. I used Beer Smith to help create the recipe. After I mashed and sparged I took a gravity reading of the pre-boil and it was around 1.04ish. Beer smith uses this number to caSculate the extraction efficiency. Using this number gave me a terrible efficiency result. However, when I boiled down to my target volume my gravity was much closer to the target 1.062, thus bumping my efficiency up.
My question is, which reading do you use to calculate your efficiency? It doesn't make sense to me to use the pre-boil reading since this is not the volume you will be fermenting at. When designing a recipe, which gravity reading should I use as my OG?
I have yet to read a clear answer.....
