The sparge itself wouldn't be hard - you can just raise the colander and pour water over the grain bed..IMO, sparge water doesn't need to be warm - I used to do cold water sparges all the time and didn't see any negative effects from it. In the newest video for the small BIAC, Nathan talks about...

I haven't done a 6 gallon batch, so I can't speak to that. As for recirculating the wort while mashing, I generally keep the element set to mash temp and the pump on to slowly recirculate the wort. You don't want to recirculate too quickly, you could end up with all of the wort on top of the...

I don't ever see myself doing a 3 gallon batch, but 5 is standard (a single keg). I'd much rather have the ability to brew 6-15. I brewed 5 gallon batches up until I purchased a BIAC, and now I strictly do 10 gallon. It gives you twice as much beer for the same amount of work. If you REALLY...

As for temperature control, I've been running the glycol chiller (with water, not glycol) and it's been working great. I've had it down to 35*F for crash cooling and it had no problem with icing up around the cooling coils in the reservoir. Also, it keeps ferm temps bang on - I haven't seen the...

I'm still doing full volume mashes, and usually hit around 80%. I'm not sure how the sparge would work, unless you're doing it because of volume constraints with the BIAC. The reason I say this is that there's a significant volume of space below the colander (I'm guessing a bit over 20 liters)...

A reef chiller would likely work for controlling ferm temps, my concern with going that route was for lagering temps, though it could very well work. I'm in the process of doing my first batch with the glycol chiller. The pump on my chiller runs non-stop (mixes and pumps), so I decided to run...

I think what Nathan is referring to would have you using your hot and cold water from your taps, as that's what he advertises as a method for chilling. I've been working on setting up a glycol chiller (though I'm using only water) to chill during fermentation, along with lagering and cold...

Glad to see you found our website :mug: I believe there's more than 20 liters of water below the colander - I measured previously and it was 20 liters or more just in the cone. I just brew as if I was doing a full volume BIAB - all of my water and grain gets mashed, and I recirculate to keep...

Picked up the glycol chiller today - it fit perfectly in my girlfriends Fiat 500 :D

Started gearing up an exhaust hood for the BIAC yesterday. I have the port installed on the house, duct work started, and the hood ready to mount.

A friend of mine just opened a brewery around Christmas time and he purchased it to chill his tanks. He's grown since then and is now having a custom chiller made for his system. :mug:

Glycol chiller that will soon be in use. My basement is typically fairly cool, but I wouldn't be able to crash cool or lager without this. Can't wait to get it all up and running!

Yeah, it glides like it's on ice and the legs are rock solid. No concern with moving it 20' full of wort :rockin:

I love my BIAC. I've only brewed on it once, but it was an enjoyable experience! You can't beat the service, the product is well made, and it's an ingenious design. The best part of all is not having to do any work during brew day. You literally fire this thing up and when the boil is finished...

I'm not sure of actual weight, but it's not fun to move up and down stairs. It's simple if you have 2 people but I wouldn't want to be moving it on a regular basis.

Some chilling action

I did a full volume mash/no sparge - it was 56.5 liters of water and 26lbs of grain. I hit about 75% mash efficiency, though I expect 80% shouldn't be a problem with some fresher grain..this stuff has been kicking around for a while and I just wanted to use it up. As you can tell by the ring...

My basement is actually sitting at about 67, so I figured I'd leave it off for now. I will be purchasing a glycol chiller in the near future that will be hooked up to the jacket for fermenting/cold crashing.

The biggest thing is that I should have put a valve between the chilling solenoid and the conical. The jacket holds a fair amount of water and will come rushing out pretty quick when you disconnect the solenoid. I probably could have engaged the solenoid with the feed hose disconnected to allow...

Did the first brew on the new system last night. Everything went pretty good for the first time around. I learned a few things to keep in mind for the next time.
