[quote=“daled”]Got it on the extra malt. When the recipies are made, are they based on an efficiency of 100% ?
I have been double crushing lately, which probably helped on my efficiency. I haven’t had any stuck runoffs yet.
I don’t measure what goes in the fermenter. I had one marked at on time, but the ones I use now are’nt marked, yet.
One other question, Do you guys ever add water to the fermenter if you boiled off too much? I tried it once and came up with a bad beer, so now I just live with a little less, but better beer.[/quote]
If you don’t know how much is going into the fermenter, your efficiency is an educated guess. note: I don’t measure mine either, I boil down to the OG I want.
[quote=“daled”]The low OG happens fairly regular. I measure with a gratuated pitcher as the wort exits the mash tun, so my preboil volumes are pretty close.
The amount that I bottle reflects the amount lost to the boil, for this example it was 2.5 gallons.
The 2.5 gallons also would include the amount left behind in the fermenter. It may be less than a pint, but it still contributes to the error factor.
