And a large boil kettle
I just did my first 15 gal biab batch.
15 Kilo of grain
7 Maris otter
7 bo pils
1 Cara Amber
100L Kettle, started with 80L water.
After mash I ended up with 70L of 1.040
Final result was 60L of 10.52 or so, with lots of trub in the fermenter.
I made a few mistakes:
I calculated using 100% mash eff by accident (I ended with about 80%) so 20% more grain would have been appropriate
I should have started with another 20%(16L) of water as well. The kettle was pretty full so I probably would have had to sparge it in.
I detached one of the rings of my bag to try to rinse the grain, but the bag ripped.
If bag didnt rip and completely drained, I probably would have gotten another 2L or so of wort
Some Statistics:
It was a nice cool summer day, mash went from 149 to 146 over 1 hr period (1 Deg per 20 min)
When heating 80L of water, it took 115 Min to go from 82.4 F to 154.5. using a 5000w element on Full.
I used a wine whip to mix mash in for about 5 min, I was kinda goofing around with it. Lost 4.5 deg in process.
with 70L, it took 40 min to go from 168F to boil rollover.
I use 50ft of copper 1/2 immersion chiller and didnt measure cooling performance, but will next time.
