Mine didn't have a printed manual, I'm not sure there is one. I got a tablet and it came loaded on that.
cmb My question is: with the BIAB BB do you remove the false bottom along with the grain bag prior to starting the boil
Like stlblue says, It just stays in during the boil. It also keeps the immersions chiller, if you are using one) off the heating element.
The biab system looks to be just a false bottom. The cofi system is a basket.
That is the older version. The newer version is a false bottom and bag.
Is anyone using the iPad app? ...
Borneogoat: A question for the BB users with many batches under their belt: what kind of efficiency are you getting? I'm referring to Total Efficiency as you would calculate with Beersmith.

After quite a bit of playing I've settled into a .050" mill gap with double crush, running a quite good flow on recirculation, moving from the steamer basket to a false bottom, using a wilser bag, I get a 72% brew house and 85% mash efficiency. I do have a dip tube and do a 90min boil on everything. This is with a typical grain bill on 5-10gal batch.
Recently did a Russian Imperial Stout with a 26lb grain bill for 5gal batch. Planned on my usual efficiencies and I was way wrong, ended up with a 65% for both brew house and mash. Luckily had enough DME on hand to compensate.

What are you getting efficiency wise and got any advice?
A couple of you mentioned adjusting the pump during mash recirculation. I've been running mine full open each time and hadn't even considered restricting it. I've been assuming maximum flow would equal best efficiency.... Is there any reason I shouldn't be running the pump wide open?
Seems people crush the grain to different levels, e.g. schiersteinbrewing = .050" vs MerlinWerks = .039". Is this personal preference or COFI vs Bag or something else? I've been assuming a finer crush would equal a greater efficiency. Maybe that isn't true???
I've also wondered about the circulation in a partially full COFI. If a COFI is 2/3 full of grain, say 15lbs which is common, then the resistance to wort flowing through the lower 2/3 of the holes of the copper pipe will be greater than the resistance through the holes the upper 1/3. Liquids generally flow through the path of least resistance and it follows that less wort will flow through the grain-hindered lower holes than the grain-free upper holes.

I ran a .030 gap for quite a few batches and even with the pump output pretty restricted I would pump all the wort from under the basket/bag and have excess wort on top of the grains. In a sense a stuck sparge. I kept adjusting my mill out until the issue stopped which was around .037.

I tried the coarse grind method, loved it and haven't looked back since.
Lubing the propeller did the trick
Schumed what type of lube did you use? Can you access the propeller by taking the plate off the front with the 4 screws? Also, is this something that should be maintained from time to time?
I also apologize if you already answered this question. I am only on page 45 of the forum catching up with all the posts.

I'll try this out, I'm interested to see how it works for me. Are you using the COFI or a bag? Did you notice an improvement in efficiency? Any improvement in taste/quality? I see according to different people on that thread that it seems results may vary.

I just used a little.olive oil and yeah the 4 screws takes off the head then there is 4 more screws to get to the housing of the propeller ...not sure what the typical maintenance schedule should be

Keep in mind that once you remove the back plate from the head assembly there is a very thin, clear silicone o-ring for a seal. When you reassemble, a light coating of keg lube on this o-ring is not a bad idea. I usually disassemble mine every 6 or 7 batches to inspect for any funk...
I am using a bag and a False bottom. I jumped from 75% mash eff to 80% on a typical grain bill. Did an ordinary bitter, pretty small grain bill I hit 86%. Taste and quality, I haven't noticed any difference.
I am considering buying the Brew-Boss. I have only read good things thus far about Darin and his system. Does anyone have any bad experiences using is system. One thing that bothered me was the 90 day warranty. Anyone have the brew boss crap out on them?
