The extra water i added maybe a quater gallon to the HLT, it was leaking at first, so maybe there but that shouldn't account for the extra i must have had the calculator set up on "365" for a high amount of trub loss. Anyway would not getting all of the water from the MLT knock points off on gravity?
It would cost you efficiency, yes. Any sugars that were in remaining 2 gallons weren't in your boil kettle. That said, if those two gallons would have been your 8th and 9th gallons, you wouldn't have wanted them anyway.
I still don't completely understand how you got all this water. You put 9.84 in and got 9.5 out; that shouldn't be possible. An extra quart doesn't change that. I think your measurements are way off somewhere, but I can't follow things enough to understand where.
Here's what I think I understand:
1) You mashed with 3.84 gallons. Of that, about 1.4 gallons would have been absorbed by the grain, giving you 2.4 gallons of water that eventually ran off into your kettle.
2) Then you sparged with 5.75 gallons (6 gallons, minus the 1/2 gallon left over in the HLT, plus the 1/4 gallon you added to the leaking HLT)?
3) You stoped the sparging when there was still 2 gallons in there, thus only 3.75 gallons of the sparge water made it into your kettle.
4) Thus, in your boil kettle, you had about 6.15 gallons after mashing? Is that right? This is where I am still confused. And the gravity of this 6.15 gallons was 1.023?
to answer your question about my pre boil measurement i took the sample after i vourlouf and had about a gallon or two in my brew kettle. so now looking at your question of "my first runnings" i think i did the whole process wrong. I waited till the mash timer went off, then just vourlof and started sparging the whole thing. Am i supposed to vourlof get clear runnings, run out the entire mash tun, then sparge with my sparge water.
Not all the way out, but typically with fly sparging you want to have an inch or so of liquid above your grain bed. Drain your tun to an inch, then use your fly sparging device to keep it at that level. If you started fly sparging right away, that could have been a factor that hurt your efficiency.
and you asked me how much volume i am talking about on my pre boil gravity reading? i dont know what that means
When you saw your pre-boil gravity was 1.023, how much water did you have in your boil kettle? Gravity itself doesn't tell you how much sugar you have. It only tells you how much sugar you have per unit of volume.
i didnt know i was suppose to take so many readings just when i mash out and after the boil is all ive done on brew day but this is the second one ha
Generally you won't need to, but when you're using a new system it's useful information for trouble shooting.
yeah i know i rarely use punctuation - it makes reading a mystery
and i dont know if im using the term vourlof right ( recycle the wort i believe) and i know im spelling it wrong
