Unboxing Colorado Brewing Systems new Single Vessel System

[akthor]

Oh wait I do have a pic of it from way back when I got it to make sure it fit.

 

[wyowolf]

Interesting, where did you get that? How is it attached?

 

[akthor]

In the for sale section here. It attaches with tri clamps.

 

[30Bones]

No way that would work on 10 gallon batches and a 20 gallon kettle, it would be buried in the grain bed.

Have not contacted Tim on the basket, but he is sending me a new recirc piece to see if that stays attached better.

I looked around and didnt see it. is there a specific name for it?

I think I am going to use some bolts to raise the screen up the top of the kettle... this will keep the grain from going over the sides with ten gal batches. This way I wont have to use my pulley to suspend it like I do now...

Got my new recirc piece. Looks no different from the original and still a terrible design. I will come up with a fix for this over the winter.

 

[Eamster]

I got a new one because mine kept bending at the fork. And this one is doing the trick. Same design but had less space between the fork and seemed to be welded better. Hope it holds. Two brews with it and and so far so good.

 

[30Bones]

I will compare to mine tonight, but at first glance it's identical in design.

 

[Eamster]

Yeah it is the same just seems like they took their time on this one. Other ones looked like a beginning welder put them together.

 

[molson]

They must have changed the design because I just got my nano system in this week and that piece is welded onto the basket. Hopefully that will work out better. Can't wait to get it all setup for my first batch. Still also trying to figure out the best route in regards to gfci. Either replace the breaker or buy an inline cord.

 

[Eamster]

They are welded on the nanos because they have a whirlpool port on the kettle. Ours can be removed so we can use it on the mash and as a whirlpool on the kettle because we don't have the dedicated whirlpool.

 

[molson]

Mine is the nano brewer home also, but I did have the whirlpool port added so I guess that's why it's welded on.

I have the same setup from July and mine is not welded.

 

[Horseflesh]

I have what molson has. Delivery was this November.

 

[jahlinux]

I'm thinking of ordering the 25gal Nano-Brewer Down Under. Does anyone use an immersion chiller? Wondering if the heating element would get damaged.

The website claims you should get 85% efficiency with these setups. Has anyone been able to get efficiencies that high?

 

[Horseflesh]

I asked about an immersion chiller touching the element and was told it was OK. (I still ended up making feet out of copper wire. I do 5 gal batches in the big 20 gal kettle so if my chiller was cockeyed resting on the element half of it would stick out of the wort.)

I've only done one batch on my Nano Home and I don't recall the efficiency figures.

 

[jahlinux]

I'm hoping I won't have any issues brewing five gallon batches in the 25 gal kettle. Tim from Colorado Brewing doesn't think I'll have any problems. He said I may need to add a little extra water if brewing a really big beer and just boil a little longer.

 

[Horseflesh]

I am sure 5 gal batches will be manageable, but I am also sure that you will need to make some accommodations. Here's how it is in the 20 gal kettle...

- You need about 4 gallons of water in the kettle to get the bottom of the basket wet.
- The recirc arm comes down to about the 10 or 11 gallon mark, meaning, a typical 5 gal batch mash with ~8 gallons total volume is WELL BELOW the wort return. So, the returning wort will splash like crazy unless you modify the return.

It was actually really easy to modify the return. I got a foot of the thick-walled silicone hose from my LHBS, with an ID big enough that I could muscle it on to the return. Then I used copper wire to wrap the hose with enough coils that I could bend it and aim it. It's ugly, but actually works pretty well. The copper makes it just strong enough that it doesn't wiggle around even when the pump is running full speed.

Between extending the recirc arm and increasing the volume of your batches I am sure you can adapt. Extending boil time means you can't play with first wort hopping though, but that's not the end of the world.

That is a neat idea, I have a similar problem and used a silicone tubing but wasn't smart enough to think of using a copper wire to make it even better. Thanks.

 

[Horseflesh]

I scrubbed the heck out of that copper with Bar Keeper's Friend in case it had any chemicals on it... I hope that was enough to make it food safe!

While the hose trick worked and it was cheap it does not really support my fetish for stainless steel. I am considering asking about a custom part in that "let me make stainless steel parts for you" thread. If we had a couple more takers it would get the price down.........

 

[jahlinux]

That is a great idea, I was wondering how low the arm went. I bet Colorado Brewing could make up an additional arm for brewing small batches.

 

[jahlinux]

So I'm really thinking of ordering the 25 gal system. Anymore thoughts out there on why I should or shouldn't? I really think it's a great design and should simplify my brew day. I'm a little concerned about people getting such low efficiencies but as long as the beer comes out good that wouldn't be a deal breaker for me.

 

[Horseflesh]

FWIW with just one batch under my belt... which may not be much...

The 20 gal kettle is functional for a 5 gal batch but I would want some extra reassurance before I got a 25 gal kettle. Maybe Tim can tell you how much volume is under the bottom of the basket. On the 20 gal kettle, it is 4 gal. Any more than that excluded from the grain bed and I could be forced into doing a longer boil just to keep mash volume up.

Though, looking at the Down Under pictures, the basket hangs from the crossbar. You could maybe rig it to hang lower? That would help.

Why the Down Under instead of the Home, unless you aim to use the whole 25 gal sometimes? The 20 gal Nano Home with the cool touchscreen is a couple hundred bucks less than the 25 gal Down Under.

I've thought about the touch screen, but I'm worried about the reliability of it. Something about basic controls I like. My dream is to someday open a nano brewery and the 25 gal system would be a great pilot brewing system.

I like the frame design on the Down Under. They are going to modify the frame so I can gravity drain from the kettle into my 30L Speidel Fermenters.

But, you are right about the price difference. And the Nano Home ships free! Not an easy decision.

 

[Horseflesh]

I decided I wanted the touchscreen because I love the idea of automation... because it helps with repeatability, and may save time. Bottom line, I am happy I did it. On my first run, I did a 2-step mash plus mash out... and didn't have to do anything for 1:34. It was glorious.

Beyond mash time and temp steps you can also program in addition timers during the boil. This is not NEARLY as useful. The UI is poor... it only shows you elapsed time, not the time left until the next step. It will beep and flash and print a message for each addition, though.

Mash and boil steps are saved in a recipe, so you can easily repeat a brew. Not sure how many recipes you can have, and you have to page through them one at a time. Not great, not too bad though.

The software is made by CBS and can be upgraded from a computer, which is great... because it has some bugs! Nothing I couldn't work around, though. I'm going to give them a report this weekend. As is, it is functional. There's absolutely room for improvement, though.

The touchscreen itself appears to be industrial gear. I looked it up, and this is probably the guy:

http://unitronicsplc.com/samba-series-samba43/#1451658074249-d6f71763-59ae

They are apparently made for use in factories. It's even IP66 water resistant. That's no guarantee it will last, but it's a big step up from say a cheap Android tablet. These are the same units that go to CBS's commercial customers... anyway, I like having it and I hope it lasts! If it craps out and CBS is out of business, you can probably buy the unit from the PLC manufacturer and install it... but I understand your concerns and share them to a degree. Simpler gadgets tend to last longer.

Regarding Nano Home vs Down Under: tough call for sure. Seems like you can save some real dough with the Home but if that 5 gallons makes a difference, so it goes.

FWIW I had no problems getting wort into the fermenter with the pump, but when I unhooked the whirlpool input I had to pinch the hose and still lost a small splash of wort. It's not elegant, but still pretty easy. A 3-way valve would be a nice upgrade but I'm not yet sure it's worth the money.

Let us know what you decide!

Well, I just ordered the 25 gallon "Down Under"

I also just found another thread about these systems https://www.homebrewtalk.com/showthread.php?t=575659

I haven't read through that one yet but will work on it later today.

If anyone knows of other threads please share the links.

 

[30Bones]

Anyone have a link or want to explain how to calibrate the PID? I have the 20 gallon and the PID doesn't have any branding on it. On their downloads page it's a one page PDF that might as well be Greek to me. [emoji16]

 

[Berchabar]

Jealous of all you guys!!!!

 

[swimIan]

I have DIY CBS system. How far under the wort level does your recirculation arm go? Is it near the surface or closer to where the grains might settle down? I'm having a difficult time finding the appropriate height to keep stable mash temps and the whirlpool stirring effect.
