Total Grain - 28 pounds
Mash tun - 10 Gallon igloo w/ false bottom
Mashed in at 165 with 8 gallons of water (beersmith said I needed 10 gallons)
Mash details - 152F for 120 Minutes
First runnings were around 1.100 @ 148 F
As I sparged and continued the extraction, I ended up coming in at around 1.075 @ 155
One key issue here was that the sparge appeared to be stuck, clogged false bottom, etc. Where there was still water above the bed (pre-sparge) and it wasn't just rushing out like usual. I used the paddle to loosen things up a bit and eventually just spun it making holes in the bed for water to pass
and I think that's where I get wrong. Without a grain bed set, the wort was just going straight through the holes I made and not the bed
So instead of an expected efficiency of 65%, my post-mash efficiency was 40%
=====
Here's how I corrected this and I really hope it doesn't go badly. First, I removed 1 of the 2 ounces of Magnum from the boil to reduce expected IBUs from 100 to 80 (now that there are less sugars)
I also kept sparging in my 7.5 gallon brew kettle until I got 7 gallons of wort. I use fermcap so I just have to watch it carefully but haven't had any boil over. and my plan is to do a 90+ minute boil until the wort volume is at 5 Gallons
This way evaporation will help me out a bit...I won't be at the expected OG but at least I'll be at 50%
Thoughts? I mean, right now, it's too late to apply any advice but next time, I'd love to know what I did wrong. I think this is it.
1. More grain than my 10 gallon cooler could take
2. Mash was too thick, needed more water
3. I should have somehow eliminated the stuck sparge
4. I should have sparged slower
Sigh.
