Dial Thermometer

Hi Guys, I have a 19L SS kettle with a weldless tap set up and also I have a Dial Thermometer With 2 Probe that is set about 2 up from the bottom which I then cover with a SS cake stand with SS bolts as legs so as not to snag the bag.
I have seen numerous photos of kettles with the Dial Thermometer sort of integrated within the tap setup.
As I am on the lookout for a larger SS kettle (approx 40L) in the near future I have wondered about this sort of set up instead of the probe and cake stand...

Bob, I had one very important post I really wanted to write tonight here before I travel but spent three and a half hours writing individual answers here first on BIABrewer and so lost my steam.

I'll try and write a full answer to your tap question above when I next get a chance but I have a lot on in the next few weeks. I have written on why taps are a problem before. A search of posts written by me with the keyword 'cylinder' and/or 'sphere' I think will give the answer to your bazillion...

Digital oven thermometer

First post by Q-Point, 5 years ago

First post

Hi all,

Just wondering if anyone has any experience with the digital oven thermometers for monitoring mash temperature. I'm thinking of buying something like this:

I'm hoping that it will allow me to monitor temperature with minimal disturbance to the insulation but I'm a bit worried that the probe/cord might not be water-proof enough for continual immersion in the mash. I'm thinking of drilling a hole in the kettle lid so that I can feed the cord through so that the probe 'dangles' in the...

Last post

Cheers! I was hoping that the inaccuracy of measuring the mash without stirring would be outweighed by the benefit of not continually opening the kettle/tun and thereby losing heat, but I guess it makes a lot of sense to get a few brews worth of accurate mash temperatures. I like the idea of the floating container too - sounds like a good solution.

Bling BIAB pasta boiler!

First post by makka, 6 years ago

First post

Just for fun but...

Anyone thought of using one of these for BIAB

23ltr, plumbing sorted, basket for your grain, temp controlled, easy drainage and it makes pasta.

Cost a lot unless you can find a second hand one.

Plus after you have finished making your brew you can alsways boil some pasta to go with your beer.

Maybe I am alone on this, but one big reason I decided to go with Biab was the minimal cost investment. This product seems functionional but not practical.

Aluminium pot for BIAB?

Can a plain old aluminium urn be safely used for BIAB? As far as I know it is but somebody on another forum seems to think it will do in the yeast and give me Altzimers.

Might of had something to worry about if youre pot was from 20 or so years ago but since then there has been many advancements in material technology and composition...and given how easy it is to sue someone for just about anything these days...id say id be fairly confident that if they are selli g pots made from aluminium it would be food safe and therefore perfectly fine to use

lifting a heavy bag full of wet grain

First post by mcgoo, 5 years ago

First post

It's not hard when doing a single 23l batch but I'm looking to do a double batch. I guess the bag will weigh approx 20kg with all that wet grain and I can't lift that on my own. So after i build a winch do I need to sit the bag into a basket or are there large strong bags that won't rip with that sort of weight.

Any tips much appreciated

Ideas for a portable hoist/stand to attach pulley.

First post by CheeseMoney, 5 years ago

First post

I live in an apartment in Southern California and brew outside. Lots of great days for brewing here. I'm looking for some type of portable stand/hoist/whatever that I can attach to a pulley system for lifting double batches of high gravity beer.

My Equipment:
Blichmann Burner with Leg Extensions
80 Quart / 75 Liter Kettle

I like high gravity brews so lifting 30+ lbs of wet grain off of an already high base could be problematic. Any ideas?

So far I have come across:
Alton Brown's Turkey...

That's a good idea. I actually like them just as A-Frame ladders because they don't have the brace/bar thingy for stability (which makes it hard to access the kettle).

Drywall Mud Masher (Potato Masher Style Mash Paddle) Safe?

First post by CheeseMoney, 5 years ago

First post

---

Went to home depot after a recommendation from this forum looking to purchase this $12 Home Depot Wal-Board Mud Mixer . However, after looking at it, the handle appears like it is painted and gobs of epoxy hold the masher to the handle. I didn't buy because it didn't appear food safe. Am I wrong?

Here is the Grainger $14 equivalent .
Maybe I should suck it up and buy a $33 Potato Masher .

Thoughts?

Last post

Just wanted to say thanks for the input. Ended up with a 24 french whip and a wooden mash paddle (dowel type) because I can use it as a measuring stick with some carefully placed burn marks. May go with a potato style masher in the future, who knows.

[I just edited this one, as well. Updated measurements for the Marshalls bag and new ones for the paint strainer bag, as well as updated my math:

Paint strainer bag: Measurements are the same as for the Marshalls bag, but the threads are thinner and that thick bar on the Marshalls bag is a thin one...

Tripod?

First post by PackerFan, 5 years ago

Right now I have a pulley mounted in the header of my garage door. I purchased an EZ-UP Canopy to do all my business outside. But now I will need a tripod to hook up to my bag. Anyone make one out of 2 x 4's or conduit?? Dutch oven tripods may work, but may not be tall enough

Last post

A tripod will be easy to make. My only worry is in my experience of lifting pumps using shear legs ( heavy duty tripod) is that if you want to lower your load adjacent to where you lifted it from you have to watch for the whole lot tipping over. If you have the skills an A frame is more stable although more complicated to make.

I’m beginning to think if I went pro I would have a whole lot of 16 gallon pots with bags, in setups like the picture below. Each pot would make two Cornys, or a firkin of real ale.

I would ferment in the kettle too for a week or ten days, so no need for extra equipment, maybe a large malt mill and an automatic keg washer :party:

Pot too big?

First post by aamcle, 6 years ago

First post

Afternoon all.

It looks like I'll have to reduce my brew length down to 10-12 litres, don't ask, my pot is a 38 litre about 37cm in diameter.

I'm worried that it's too big for small batches, that the evaporation will be simply too much.

Should I look out for a pot of say 20 litre that I could use on the stove top?

Thanks for your advice.

My 1st BIAB is getting closer, the element is fitted into my pot I just need to fit the cable and if all goes well I'll have a bag made Sat/Sun.

I got the pot ~ 38L Aluminium very cheep but with no lid, what's the best way to make one? If I buy an aluminium disk (pizza separator) it will be half the cost of the pot!

So what works?

New Syphon/Hop strainer

First post by Yeasty, 7 years ago

First post

Not wanting to drill my copper and fit a tap I have been thinking of making a Sypon/hop strainer. This is what I came up with.

Here's all the parts stripped down. I soldered the bends on one end only and slightly ovaled the other end so they were a push fit when put together. The tube is 15mm and the holes (268 of them) are 3mm.

This is the hopstrainer square put together. I wanted it to be free standing so I opted for a square shape.

And here is the whole thing.

I used it today...

LOL on the speechless bit. Seriously though, I love this and you have my brain going at a hundred miles an hour but I'm meant to be working on something else :roll:.

Do the research on the breather, you can build you own using a propane regulator from a camper (I think you blokes call campers a caravan ) for 1/3 the cost of buying.

Why do you need that fancy breather thing? Why couldn't a person hook the cask directly to a CO2 tank with a regulator set to a very low pressure?

The CO2 would probably only need to be turned on when beer ws being poured.

I picked up a 38/39l Aluminium stockpot, I'm going to use it as an electrically heated pot to mash and boil in and I would like to fit a tap.

All,

I have been doing lots of hopping experiments in the last year. I just love hops! I visit hop farms and I grow my own hops. Three varieties, Cascade, Willamette, Nugget and (E.K. Goldings Fuggles). Wait that's four! I am so bad at numbers! Personally I am narrowing down my hopping schedule (at the moment) to this.

Bob, i have started a new thread here for anybody that has hop growing knowledge. I would love to hear of any tips you have. :thumbs:
