Bag For Biab

[MVZOOM]

Oh - and I just checked that BIAB bag on Gryphon - mines a completely different shape. It has a flat sewn bottom - ie... it's basically a big square, sewn up. This means when you pull it up and grab it 1/2 way down, the grain moves itself to make an almost cylindrical shape with a conical point- this means that it comes out really easily.

I can't explain the shape! I'll have to take a happy snap for you.

Cheers - MIke

What exactly is swiss voile? I havent had a chance to go down to Spotlight and ask for it yet but I noticed we have this stuff at home that may do the job. It is a white fine mesh, possibly nylon that we used to have behind our curtains. The purpose of it was to let the light through but it made the view slightly opaque. Hopefully someone knows the stuff that I am talking about. Could this be swiss voile? It would be handy if I could use this as we have heaps of it laying around at the moment. What else is swiss voile normally used for?

Hey hsv,

From what I understand swiss voile is a curtain material, so you might have the right stuff....

Why don't you go to spot light and check out some swiss voile and see if its the same??

what does everyone use to make their BIAB bags?

I would prefer to just buy one straight out.

any suggestions? I only see hop bags.

Got some HERE. One size fits all from 40L to 100L.Real good quality and strong.

Hey Nev,

Rob where were you when I posted this
:lol:

hehe doogie.....

who holds the world record for biggest biab mash? what is the biggest batch that has been done?

 

[Thirsty Boy]

It "might" be Spills

a double batch of a strong ale - I think it ran to 17 or 18kg of dry grain?

Bag held without even a whimper. Still, its only going to weigh what... 20-25 kg on the way out so I would expect it to hold even with a grain bill that large.

i think the challenge has been set Pat a "BIAB Whole Bag Brewday" at your place,

anyone local got a 4wd with a winch on the front it could come in handy :blink:

and why is it everytime i think of BIAB my mind wanders and i end up thinking of being dominated by someone wearing fishnets?

 

[Katherine]

I did a double batch with 24Kg of grain.....

 

[wabster]

Katie was that a single layer of Swiss Voile? I've often wonder how much weight it will hold.

I went and bought about 3 metres of SV from Spotlight, and just use it loose after trimming to ensure there was plenty of excess down the sides of my 15 litre drink cooler mash tun I just put the top on when I am at the right mashing temp and use a rubber band to hold the excess Voile together over the top. That stops the siphon effect that happened the first time.

Has worked well for me the 3 times I've gone down this route. Cheerz Wab

The Bag is exactly like the ones Gryphon Brewing are selling. Held it quite easily....

Well after throwing my bag in the bin (check the BIAB register thread for why) I went into spotlight to purchase some more material.
Thanks to Thirsty's advice (pretty sure it was him) when they looked at me blankly after asking for swiss voile I told them apparently it's a curtain sheer.

Oh sure that worked didn't it! Wish I knew that the last few times I had tried looking for it! Within 5 mins I had the exact stuff needed and on my way to dick smith to get some parts for my fridgemate....but thats another story.

Anyway as mentioned check the curtain area, 100% polyester swiss voile was there.
That and some elastic came to about $11 so pretty good - oh yeah that was enough for two bags as well.

Sorry Spills I was mistaken we did two double-batches... I must of being intoxicated....

RandyRob I was talking to Patch last night about the challenge, and for now on his pretty much brewing 25kg bag brews just to cover the beer that is consumed....

I'm still a bit confused on which shape of bag people are using for BIAB now. Is it acceptable to make one with a circular bottom stitched to a cylindrical side, with a drawstring around the top of the cylindrical side, or is this not really strong enough? I am planning on only doing single batches for kegging, so unlikely to go past 5-6kgs of grain.

cheers,

Crundle

 

[Damian44]

crundle i went with the circle base and i am happy. You can reinforce the stitching by sewing another piece of cloth onto the seem. But thats probably overkill.
Just make sure your base is bigger thsn your pot. I think cloth loops are better than a draw string. The more loops the better. 2c

People are using different types of bags - it's basically up to you and for the price of it you can afford to experiment as well!
Mine is a pillow case like design with elastic sewn in to fit snug around the pot and also a drawstring above that when wanting to lift and hang it up.

As long as you have a decent strength stitch you should be fine.

I think I can say most of the BIAB guys here prefer the Singer 14SH654 4/3 Thread FREEARM Overlock Serger Machine. It does a rolled hem, differential feed, stitch width, length controls, embroidery, all the stuff a modern brewer needs. I like to embroider a Blue Willow design on my "brew pillow" so it matches my crockery. It's sooo Better Homes and Gardens! x
