So I brewed an IPA. Here's the grain bill:
10 lbs 2 row
.5 lbs crystal
.5 lbs munich
10# * 37 ppg = 370 points
.5# * 34 ppg = 17 points
.5# * 35 ppg = 17.4 points
**********************
404.5 total points / 5 gal = 80.9 ppg
I planned for 75% efficiency, so 80.9 * .75 = 60.7 points
So I was shooting for a 1.061 OG
Instead, I got 1.044. 44 points (actual)/80.9points (theoretical max points) equals 54% efficiency
Can a beer guru tell me if this looks like reasonable brew math?
I was wondering, I think I started my mash a little bit hot. Maybe 160 instead of 150. I cooled this by adding some water which I then subtracted from the sparge amount. Might this have hurt the enzyme conversion?
Also, I never really got to sparge because it turned out my grain bag (biab) wouldn't fit into my sparge pot. Stupid oversight. And then some semi-sugary sparge water got spilt and stuff.
All things considered I'm pretty sure that's why my efficiency is low. I need to streamline my process so I have no spills.
Thanks!
