Brew in a Basket...anybody try one of these?

[Yeastieboy]

Like many, my mash tun happens to be my boil kettle as well, which also includes a stainless basket that I line with a fine mesh bag during brewing. Works like a champ. Highly recommended.

My equipment is ghetto?

Nice setup The_Bishop. Hey, what's your method of chilling? My setup is very similar to yours. However, I am still disconnecting several camlocks to add a plate chiller after boil.

 

[The_Bishop]

I have a ZChiller counterflow chiller mounted at the bottom of the stand. You can see the camlock fitting on the right side of the pic.

I do have to move hoses when it's time to chill. There's a short jumper hose that goes from the pump outlet to the chiller inlet, then the hose that runs to the lid gets moved to the chiller outlet. There's locline mounted inside the lid, so I shape it to create a whirlpool with the outlet just under the surface of the wort. With the appropriate valves turned off and a small bucket to catch the few bits that drip out, it's a pretty clean process.

The ZChiller is crazy effective. Single pass, wide open flow it drops temps 74f with my cold groundwater. I usually recirculate into the kettle until I see the chiller outlet hit pitching temps (Usually in the 3-4 minute range) then run right into the fermenter.

I usually bag my hops, as a holdover from when I had a plate chiller. Next brew I'm going to forgo that practice (with pellet hops, whole leaf will still be bagged) and see what the difference is. I'm not worried about anything getting caught in the chiller anymore. Besides, it's a breeze to backflush and clean.

A great solution to a non-problem. Unless you are doing a fly sparge which should take 45 to 60 minutes, you don't need a mash out. Without heating for a mash out, no scorching.

Your perceived benefit from having the 3" legs is actually a detriment as you exclude the water that is below the screen from interacting with the grain. You end up with a situation much like "topping off" where you add water to the wort, thus diluting it. If you are recirculating, you avoid this but then you will have problems with the screen clogging unless you have grain that is milled more coarsely and then you negate the advantage of BIAB's ability to use finely milled grain. You'll end up like the dog chasing its tail.

While some have touted the longevity of the screened basket, the payback of the funds invested is too many years. You'd have been much farther ahead to replace the bag periodically and spend the extra money on ingredients. You may not live long enough to have a payback on the screened basket.

Ok this brings up an interesting question.
When I BIAB I suspend the bag in the water on a string so that it doesn't touch the bottom of my kettle. Is this incorrect?

in the picture shown above what do you circulate thru the coil of copper tubing? (please remember I am still relatively new at this). I know it is used as a wort chiller.

 

[The_Bishop]

@KenEnnis - RM-MN has his own opinion regarding the baskets, mine is different. If your setup involves recirculating your mash (as mine does) a solid basket is a huge help. It holds it's shape and flows better than the bags. That being said, if you're doing a single infusion mash a bag works well. I can multi-step mash with a mash out and have no issues. I recirculate constantly during the mash, so all the liquid is in constant motion.

The ZChiller is a counterflow chiller. It's a tube within a tube. In the outer jacket, you have cooling water flowing in the opposite way from the wort that flows in the inner tube.
This diagram illustrates it:

Another happy user of arbor baskets. I'll take this over a bag any day. Super easy to clean too.

If you recall in my earlier post (https://www.homebrewtalk.com/showpost.php?p=7576456&postcount=43), I was going to try an experiment using a 5 gal bucket as a sleeve in by brew basket. Well, I just kicked my keg of Kölsch, so it's time to brew another batch of BM Centennial Blonde. Since I have my brew log data from the last batch, it will be a great opportunity to see what difference, if any, a sleeve makes to the brew basket. I'll post the results tomorrow.

Okay, brew day is done, 22 quarts of BM Centennial Blonde (BMCB) are in the ferment chamber at 62°. So how did the sleeve work? In a word...terrible. The sleeve functioned exactly as planned, in that it kept the grain in a column with only the bottom screen as an outlet. So what's the problem? It didn't allow the wort to flow through during recirculation, even after stirring several times (e.g. every 10 minutes) during a 60 minute sacch rest. The pumped wort basically just stayed in the top of the sleeve, and overflowed down the sides. So, you ask, maybe I ground my grain too fine? Nope, I use a Schmidling MaltMill without adjustable rollers, so the grind is set to ~.045" (pretty course, no?) AND my basket's screen weave is fairly open at 600 micron. Below is a pic of the basket being brought up. Notice how high the wort sits in the sleeve? After 5-10 minutes, I couldn't get it to drain until I pulled the sleeve up about 1.5" to allow it to drain through the sides. For those of you who are "facts & data" types, here are the numbers from my first brew of BMCB and this batch (using Brewer's Friend.).

Efficiency with open basket:
Conversion: 95.4%
Pre-Boil: 89% 33.5 ppg
Ending Kettle: 83% 31.3 ppg
Brew House: 83% 31.3 ppg

Efficiency with sleeve:
Conversion: 82.3%
Pre-Boil: 78% 29.2 ppg
Ending Kettle: 80% 30 ppg
Brew House: 76% 28.7 ppg

There were some slight recipe differences in the type of grain, but nothing that would cause this. So, based on my experiment and observations, I will stick with my open sided basket (the sleeve now sits in the trash bin.)

BTW, @RachmaelBenApplebaum, while my rig is nowhere as nice as The_Bishop's or jimyson's, it serves my purpose well. If I had the $ to invest in a "...proper mash tun? I mean, a ported kettle with tc fittings and a thermowell?", I'd just buy a Grainfather and be done with it. As others have already pointed out, this is a BIAB forum, the last "B" can either be a bag or basket (or combination.) I was just testing the concept of full flow vs vertical flow of wort through the grain bed vis-a-vis impact on efficiency.

 

[The_Bishop]

Ah, it sucks about your difficulties. On the other hand, now we have data about open sides vs. closed basket.

Thanks for the experiment, anyway!

You're more than welcome! It was worth finding out what gives, and I'm glad it only cost me a $5 bucket from Lowe's rather than going "all in" and buying a solid sided basket or a SS sleeve. I'm guessing/hoping the beer will still come out well (it's possibly the most forgiving recipe out there,) so it's not a total bust. There were quite a few differences in the efficiencies, weren't there?

 

[RachmaelBenApplebaum]

My equipment is ghetto?

No, mine is. I guess what I meant is if you have tc fittings anywhere in your household, you probably don't mind spending money on nice equipment. As for a proper mash tun, something with a false bottom so you can mash? I guess the BIABers get offended by the idea.

 

[The_Bishop]

I can mash just fine. Instead of using a dedicated mash tun with a false bottom (Which I have done in the past) I have a 400 micron stainless mesh basket that I mash in. In fact, I have pinpoint temperature control over my mash temps and I recirculate the whole time, which leads to greater conversion efficiency and makes step mashing as easy as turning a dial. I can do things with a mash that I could never do with a cooler/false bottom setup and my brewhouse efficiency is normally in the 80% range. My 'mash tun' has zero dead space loss and I never have a stuck sparge.

Tell me again, how is a 'conventional' mash tun better?

Amen! And thanks for the detailed reply regarding your chilling setup!

Unhelpful and unproductive comment. Self-edited.

 

[Epos7]

Lots of good information in this thread. From what has been reported, it sounds like brewing in a basket with solid sides is more finicky than in a full mesh basket.

Colorado Brewing Systems use a hard sided basket in their systems, as seen

They have a 400 micron mesh in the bottom of it.

RedlegEd, I'm curious if when you tried a sleeve in your basket, were you recirculating the wort into the top of the basket itself, or into the bottom? In the video above, they are using a fitting that seems like it would reach most, if not all of the way to the bottom of the basket. I wonder if this is important to keep the grain flowing near the bottom of the basket and not clog the mesh screen.

 

[RedlegEd]

I pumped onto the top of the sleeve. I think even had I pumped to the bottom, it wouldn't flow through. Remember, my screen is 600 micron (larger openings than 400 micron,) so I can't see how it would have made much difference if the bottom of the screen was plugged. The wort would have backed up and overflowed the sides. I do agree that may have increased the exposure of the mash to recirculating wort, but not to the point we're it would even come close to the efficiencies I achieved using an open basket.

 

[stonebrewer]

I think the difference in your results may be due to CBS doing a whirlpool to get the mash moving vice pouring wort on top the mash. They achieve high 80's in efficiency with this setup. Seems to make sense and is what I wanted to do with my system. Gotta get some electrical issues resolved first, but then I plan on using my Spin Cycle from Bobby M to do that in a basket without hard sides...not sure if that will work or not, and it will require me to modify the way the Spin Cycle attaches to my kettle, but heck it is worth the experiment. If/when I get around to it I will post some results and pics. Cheers!

 

[Epos7]

I think you're right stonebrewer. It appears that by creating a whirlpool within the basket, CBO is able to keep the grains suspended rather than settling to the bottom and clogging the screen. It seems like the solid sided basket is critical for creating said whirlpool.

I'll be interested to hear how your experiment works out. What is the Spin Cycle you are referencing?

It's a whirlpool fitting...see URL to Bobby M's (HBT sponsor) product. Right now I have it bolted to the side of my pot as a whirlpool. Will likely have to extend it away from the kettle side to get it into the basket...probably with a short piece of stainless pipe, but gotta figure that out still.

 

[Epos7]

That's pretty cool. Looks very similar to the tri clover fitting CBO is using, which they appear to be getting great results with.

 

[The_Bishop]

I'm using an open sided basket, with loc-line from a fitting on the lid. I orient the loc-line to create a whirlpool in the basket, and while it's not spinning madly it is still moving in a circular direction.

Is it possible that it's crush size related? How fine is your crush? *edit* Doh. Just re-read the post. Yeah, that's not too fine at all.
