Hi Everyone,
Moving from Kit (skipping Extract) to all grain BIAB.
Want to get my hands on a pot (i have gas burner + bag), but not sure how big a pot I need.
My FV is a plastic bin (25L - standard coopers plastic one) with airlock.
How big does my pot need to be so that I can add water + grains and come out with enough to fill my FV, but obviously leave space for krausen etc. I am not sure on the calculations involved, but pretty sure with boiling off and adding grain, a 25L pot is too small?
thanks!

I would try and get at least a 40l pot, I know with my setup, depending on the recipe my volume for 20l-21l into the fermenter is about 36-38l with all the grain and water added.
You want to leave yourself a little head space, cause when you lift the bag the wort will rise up with it until there's room at the sides for it to flow.
I use a 50l keggle and find that it does single batches quiet comfortably, I don't have to worry about overflows or boil overs.
Good luck with the search for a pot.
Cheers wiz

Thanks Wiz.
I heard a decent ratio is 3.46l of water per 1kg of malt (averaged for malt) for mashing, does this sound too low?
Is there also a chart that would tell me how much I would lose to evaporation while the boil is on over an hour?
I guess what i want is . X malt X y Water = input. - What i lose to evaporation = final brew length of 23L.

I would recommend a 70L pot.
I have a 50L (40x40cm) which is perfect for 23L, but I want to do double batches, 20L now and 20L for later and that is very tight with a 50L pot
You can do 23L with a 19L pot following Nazi biab

Oh my.
Due to an iPhone bug I ended up submitting that blind. Looks like it auto-corrected maxi biab!

hahahah..i had a good laugh at Nazi Biab 
I have managed to find a well priced 36.6l and 40l pot locally, which i will more than likely get my hands on, by my elementary calculations, i should get by no problem for one batch of 23 - 25 with a 40l including grain, water, evaporation and sparge.
Thanks.

Hey SP, have a read of this post which talks on the pros and cons of various kettle sizes. It might help you with your decision.

I'm in the process of deciding which size as pot to get. I think maybe a 46 L will be the way to start as I don't want anything too restrictive. Not planning any double batches just yet...

A kettle purchase is always a big decision Paul. There are so many factors to consider and a lot of them you don't predict.
I would have never predicted doing double-batches but now I have two 70 L kettles and often do two brews side by side of double batches. I never intended doing double batches but many times I have had a fellow brewer over and we have shared the brew day spoils, labour and company.
The 70 L is also a very comfortable pot to do a single batch in - no worries of boil-overs etc. It also does not cost that much more than a smaller pot.
One thing I have been meaning to do but haven't as yet, is when brewing on my own, to double-batch and chill half the brew and no-chill the other.
So many possibilities!

Thanks for the advice. It's also the explaining to the wife why I need to spend so much on a large pot... But I'm only just starting off with BIAB and I think there will always room to upgrade along the way. Is there any better prices around compared to Keg King for stainless steel pots? What is a good size Mongolian burner for a 46 L pot to heat it up efficiently?
Cheers,
Paul.

Beerlegs, there are always cheaper options. Pubs often leave 50 litre (potential) pots outside all the time. I'm not advocating that you help yourself to one, but many others have in the past. If money is an issue, aluminium pots are much cheaper and will still make beer. Heck, if you can find an old earthen pot I'm sure it would also work. Don't get sucked in to "it has to be this or that", brewing is limited only by your imagination.
Burners are another issue, I use a 4 ring burner and this is ample. Others use a 3 ring burner (cheaper) and still make beer. So long as whatever you buy will give a good rolling boil, that's all you need.
Life's to short to complicate it.

I'm planning on watching a BIAB demonstration at Grain & Grape first to see what they use before buying anything. I want to get a good size SS pot, maybe leaning towards either 46-70 L pot now. Just so I don't have to buy another one later and double batches can't be a bad thing! My wifes supporting the garage brewery which also helps. I'm looking toward to building a immersion chiller out of Cooper coil after my pot purchase. And I'm sure to get plenty of advice from other fellow brewers here :-)
Cheers,
Paul

Nice work Paul. I think you'll be really pleased with the versatility of the 70 litre pot
