Unboxing the Nano from CO Brewing

[swimIan]

3 gallons under. I had a port under the basket and a diy recirc arm on top. It was better circulation in both places during the mash but different grain bills really messed with the flow rate and as a result the temp control parameters.

I found the keys to these systems are the right size crush, the SS manifold, stiring a couple of times during mash and rice hulls.

My wort is crystal clear until I hoist the basket... what I boil doesn’t look at all like the clear wort on top of the grain bed!

pull the basket out really slow.. allow it to drain slowly out. just before the bottom breaks the surface pull it quicker though. the dunking action seems to draw small particles at the end

I agree with this completely as an FYI. These things are a staple of my brewing although I don't always stir three time usually at dough in at first mash temp then maybe once again but not always. Per a reference above though it was stated that the recirc should be left of the siphon and run clockwise. I run mine like in the picture (right side and counter clockwise since I don't have a port to the left although I could reposition the siphon I suppose. My whirlpool works fine counter clockwise so Im not sure why it "should" be the other way but im open to hearing why.

How many microns is the bottom filter on the basket?

 

[Dockside_Brewing]

I am sure it is a small part of the equation but north of the equator vortices run clockwise so I am just going with the flow and mother nature. There was a study done, Experiments with a Whirlpool Tank. By G. Van Gheluwe and M. Dadic Molson Breweries published in The Brewers Digest, September 1972 . In the study, many factors were studied. Their research showed an increase in sedimentation of 6.2 % by running counter clockwise vs. clockwise so why not go clockwise.

I'm thinking of installing a Unistrut Trolly above my 25 gal Down Under and getting rid of the hoist bar that came with it. My system is setup in the basement so I can attach everything to the basement ceiling. I'm looking to make getting the grain basket out of the kettle an easier task for one person. Has anyone installed something similar? I'd appreciate any pictures.

Well you talked me into it. Just installed it and I love it! Simple and so easy to roll! All parts from amazon. 5 foot section plus trolley and brackets right at $100.00 .

Glad it worked out. I think I'll place an order myself.

Ill look to see how I can replumb to run it the other way but may be tough but worth the experiment if it improves it. Wont be as easy in my setup as just switching things around but may still be possible

I haven't pulled the trigger on the Nano yet, but based on this, I have turned the whirlpool fitting on my SS Brewtech kettle to flow clockwise.

Probably not a big deal but if you can do it without a huge hassle why not.

Can you link to the exact parts you used, please? This looks like a great idea.

You will need two of these.

Thank you - I figured as much and ordered all the parts yesterday. Excellent solution

Finally got to try out the Unistrut trolly system. Works great! The trolly moves very easy, almost too easy, but it's a lot better than lifting the basket off the hoist and into the bucket by hand.

I just received my unistrut parts. For the ends of the rail, I noticed you have bolts through the rail to block the trolley from coming out the end. Did your unistrut come with these holes pre drilled? Mine did not

No I just drilled the holes myself.

 

[Dockside_Brewing]

I also just drilled out each end and added a 1/4 inch bolt for stops.

So after a couple years with my CO BIAB setup and having enough issues that made me almost quit the hobby I decided to dual purpose my 65 quart camping cooler to a MT. Years ago I used the Coleman Extreme for a MT with success and then I got the BIAB bug.

My 20 gallon electric kettle will now be my HLT and BK and my mash process is now back to being simple, quite, virtually trouble free and cleaning will actually be easier.

I made a CPVC manifold/false bottom. Close to one thousand holes in this sucker

Sorry you've had bad experiences. I have done maybe 60 brew days with my system now and while I have had a few minor issues I was able to work around them with no problems and have been VERY happy with my system. My pump did fail and I had to replace it but I am actually happier with the chugger in place.

I agree, the system works great. It took me a while to get BeerSmith dialed in, but now I consistently hit my numbers and the beer is coming out awesome.

Care to share your beersmith numbers? I have used a basic biab calculator in the past, but now want something better.

Thanks!

• Mash re circulation (IMHO it's not needed) created a lot of issues from wort not getting through the bed fast enough to starve the element and fry it (multiple times) if you walked away for a hot minute, along with massive temp differences, constant stirring of the grains to keep the flow going no matter the grain crush it seemed. My basket is the solid sided, mesh bottom. Pump has always been my old chugger. I sent the silly pump it came with back once I unboxed it.
• Constant pump adjustment and babysitting. I think it leaves a lot to be desired. Some love it, I liked it, but far from love
• Efficiency was always all over the map and hitting my numbers was never consistent.
• Stainless basket is/was a PITA to clean

I have a 20 gallon basket, stainless frame and pulley setup for sale if anyone is interested that is wanting to DIY a setup like this

Sure, Ive attached a screenshot of the equipment profile page. My next batch I'll be changing the efficiency to 68% it's currently set to 67%. I only have a 1 gallon boil off because I use a steam condenser that allows me to boil with the kettle lid on. I also changed the BIAB Grain Absorption to 0.8000 fl oz/oz.

I've had good luck with re-circulation using a bag.

I am of the mindset reticulation is not needed. I also think my beer made before in a cooler MT was better. Could be me and I am not knocking the COBS setup one bit. Just had a shortcoming I fixed and in reality it didn't cost me anything to do it. I had everything minus the $10 in CPVC

I'd like to eliminate recirculation from my process but I find it the only way to nail my target temps. The new system from SS Brewtech looks very interesting (20g version on the way) but I'd need to build my own stand with a hoist.

What is wrong with the recirculation process? I'm hitting my pre-boil gravities, beer is turning out just as good if not better then when I used a cooler. I can maintain a constant mash temp. I'm very happy with the CBS setup. It did take some time to fine tune it to BeerSmith, but now that I've got that figured out everything is good.

I found my solid-side basket COBS system much easier to use when I made a couple of tweaks.

1. Adding the Ss manifold... the single return hose was no good, at least in my small batches with a very thick mash.

2. Not being afraid to run the pump slowly. Any amount of turnover seems to be adequate, really. So I start the mash with the pump throttled way down, slow enough to be at no risk of overdoing it... and I try to forget about it for 10-15 minutes, at which point I turn it up a bit. Having the sight glass makes it easy to monitor, it only takes a minute to see if an adjustment is going to be safe.

When I insisted on running the pump as fast as possible at all times, it was far from relaxing.
