So, here's a question from the newby....
I put my first brew in the calculator long before starting (it's an extract with some steeping grains; and I did go ahead with real pumpkin too) ... calculator said my OG should be 1.058, I used 30% efficiency in the caculator.
I ended up at 1.060-1.061 when it went into the fermenter.
Now, after steeping grains and pumpkin and bringing the volume up to 3 gallons (temp was probably 155-160 range, but I didn't check it?) .. I had a gravity of 1.015
I put the grains and wort volume that I had into two different brewhouse efficiency calculators and it's giving me 37%; not considering the pumpkin.
So.... the gap between 30% and 37% might explain the 2-3 point difference in expected vs actual OG? Or am I over-simplifying something that should only be used in all grain brewing? (and perhaps I needed to pay attention to tempuratures and adjust for this?)
The yeast I used says on the package up to 1.060, so I guess I'm pushing it, getting a few bubbles now, so hopefully I'm ok.
I've got Papazian Homebrewing book and will crack that open tonight, but I'm in impatient fellow on my quest to learn and I know there are experienced brewers here ...
