I just brewed my 4th batch, which is an extract recipe for stone IPA. I made my first attempt at getting an OG reading as I just purchased a thief this week. Not sure if I did it correctly. After pouring wort and adding water to get to 5 gallons I got my sample. Reading was 1.056 after adjusting for temperature. Recipe states it should be 1.065. That seems pretty far off. One thing I thought of is that perhaps I did not wait long enough for all the hops / trub to settle in the bottom first. I just took the picture below after pitching the yeast, it has been sitting for 20 mins or so at this point.
When I obtained the sample a lot of that trub at the bottom was still swirling around after I aerated it. Should I have waited till it looked like the picture to obtain the OG sample? If my OG is actually that far off is it bad and what could I do to fix that in the future?
Thanks.for any advice.
