Divrguy,

Is it 100% Polyester? It doesn't look big enough to go around my kettle. May do for a reusable hop sack? Good find.

Hi there Divurgy,

The thing you'll have to look at is the porosity. I've noticed a few people are using bags that are very coarse. What I recommend is a bag which has 30-40 threads per cm. Unfortunately, the only way to check this is with a strong magnifying glass :sad:.

Mind you, if you can count the threads without a magnifying glass, then your bag will definitely be on the coarse side.

I've never brewed with a coarse bag so I'm not too sure how much of a problem it is :think:. The worst that will happen is that you'll get a lot of grain particles in the boil which will lead to more kettle trub and, possibly, a tannin problem.

See how you go ;),

Okay, if it is like the MoreBeer ones then it is very coarse. The original BIAB bag is much finer. I think my first bag was around 30 threads per cm. My existing bag is 40. That means 900-1600 holes per square cm. A coarse mesh might only be about 50 holes per square cm. So there is a big difference.

I reckon just see how you go. Also what Bob said above, it is important that the bag lines your kettle. Having the grain restricted can make a big difference. But, I think you're okay for that :peace:.

;)

That's great news Divurgy :peace:. It's always hard looking at pictures of BIAB bags and trying to tell if the bag is fine enough. And I don't htink too many of us have strong magnifying glasses lying around :P.

I would think that if it is like laundry bags I have seen and used then you may as well use a fish net. Laundry bags are designed to keep your gear in them, and allow plenty of water to flow through, otherwise the gear in the bag is not going to get washed.

I used a laundry bag for my first 10 or so brews.It was well worn to begin with and soon broke down.However I recently made my own out of curtain voil and it was the finest weave I could find at the fabric store.This material was VERY similar to my old laundry bag.I have also recently purchased one from a guy over at HBT (not eoin) and it to is very similar to my original.Go for it and stock up Divrguy,at that price you hardly need to wash them!
I have a BB&B close to me and will see if they are available up here in the America's hat.
P.S. Bob I don't think they are meant to go into the laundry,just go too the laundry.But what do I know, I am only allowed to wash jeans and socks!
AWOL

I checked 2 of our local BB&B's and they didn't have any but the 3rd one I went to had a whole shelf full. Having struck the motherload (and the fact that they are $2.99 ea) I bought a half dozen.

I finally had a chance to get a close look at one last night, I believe these may do the trick! The weave is not quite as fine as my custom bag from Jeff but it is definitely finer than muslin, paint strainer bags, grain bags that the LHBS sells, etc. I'll try to post a picture soon comparing the weave.

I need to knock off a 10 gallon batch this weekend for an upcoming party, I'll give this new bag a try and report back.

I picked up a few of these bags- they will work great with a keggle, but not fit with my 15 gallon kettle.

Attached picture shows a comparison to voile material and the laundry bag. The laundry bag has a coarse mesh of thicker threads, with a fine mesh in the gaps. Still slightly coarser overall than voile, but definitely looks usable.

Thanks for the tip Divrguy!

Thanks for saving me the trouble of posting a pic yarrr ("yarrr"...is that pirate speak?)

Anyhoo, gonna run a batch through this bag tonight and I'll post thoughts as to how it compares to my voile bag. Stay tuned....

Half way through my boil now. Impressions: The herringbone weave of this bag is actually much finer than it looks in the picture. It drains just slightly faster that my custom voile bag which is actually a plus for me (my voile bag weave is really really fine).

With apologies to the guys that sell custom bags.....this thing rocks! I would recommend everybody that can find these at BB&B go buy a few, especially at $2.99. I've got 6 and am thinking about getting a few more to hand out to newbies in my area that are thinking about BIAB.

I went to Bed Bath Beyond and got 2 of the laundry bags (they were $5.99 not $2.99). (I couldn't tell what the material was, Nylon or polyester? It was some synthetic. They also had cotton which I didn't get)

I tested the bag out in a pot of water and unfortunately it held the water and didn't let it drain. The weave is too fine and thus the BBB laundry bag made of synthetic material is unsuitable for BIAB.

One possibility is this is a new bag, better constructed for being a laundry bag, but useless for BIAB :-(

I will try the cotton bag, but I am concerned it will absorb too much wort.


Note - this bag is not the same one listed above. SO I have to assume that the BBB near me doesnt carry that type of bag and has a "better" bag which is useless for BIAB.
So if looking for a bag at BBB make sure its not the "good" $5.99 one :angry:

ArcLight,

Did you get the exact one pictured at the top of this thread with the weave as shown in "yarrr's" post above? There are several brands and types at my local BBB but the only one suitable for our use is the one pictured. I have brewed twice with it now and it works as well as the custom made voile bag I have used for years. All the bags that I have used thus far will hold liquid (to a point) or drain painfully slow and need to be squeezed/wrung out to get all of the liquid out.

I suppose they could have changed material (that would explain why we all found them for $2.99....closeout?), that would be unfortunate as this was a great source for an excellent bag, cheap!

Checked BB&B yesterday. It looks like that bag was on clearance. The new bags have very large holes. If anybody finds the one pictured at the top of this thread, I'd be happy to reimburse you if you are willing to buy it and mail it to me!

I found the one pictured below and it looks interesting. I have a small pot (half batches) that it should fit in. The handles would make it easy to lift. The questions arewhether the "straps" that go around the bag would absorb too much wort and how well the square shape would work.

The mesh is pretty fine, but the voile is probably finer.

Old thread, I know. I waited too long to go to BB&B and when I finally did, these clearance bags were long gone. I've been looking around ever since for a similar bag. A couple weeks ago I found one for $5 at Marshall's, near the checkout line. I think it may be the same bag.

I do not have a commercially-made BIAB bag, so I cannot compare them. The original thread on the Homebrew Talk forum had this comment: "I used it this past weekend and you guys are right. A bit finer than the paint strainer but slightly (and I mean slightly) coarser than the usual voille bags."

smyrnaquince,

It may work but in a pinch but "Shear Drapery Material" Will let you fit your pot perfectly! It's cheap! You just need someone to sew a bag with nylon thread.

I need to tweak this video but look here. http://youtu.be/c9hpU3iw4Zo
