So I have worked out the bugs of my AG equipment and went from mid-60's to 75, 80, & 83% efficiency based on a pre-boil volume of around 7 gal.
Yesterday I hit 80% efficiency but missed my OG by 6 points. Heres the data:
Irish Red Test
8 lb. US 2-row
1 lb. Munich
.5 lb. Crystal 40
.5 lb. Crystal 80
.5 lb. Victory
.25 lb. Cara-pils
.125 lb. roasted barley
60 min mash in a coleman 48Q cooler with copper slotted manifold.
Mash at 154º I use PH 5.2
Add 2 Q boiling water to get grainbed up to 161º, stir good and let er rip.
1st mash out @ 1.063 SG
two equal size batch sparges of 2-1/2 gal of 175º water - grain bed up to 167º
last sparge runnings @1.022
Collected 7 gal pre-boil @ 1.045 SG
My evap rate is quite high. 60 min boil and I'm down to about 5.25 gal.
My measured SG post boil is 1.052. This is 6 points off my beersmitch calc.
I have efficiency set at 78% in beersmith. I mash at 1.3 qt/lb.
I don't get it. If my eff is up there, I should be hitting my target OG of 1.058, but only got 1.052.
My previous Brown was 2 points higher. Previous to that, my stout was 4 points lower. Previous to that my Hobgoblin was right on at 1.056
What am I doing wrong?
