If you are using a fine mesh bag and are only getting 72% efficiency you need to double crush your grains because the particle size it too big. With the bag you shouldn't have to worry about a stuck sparge or even lautering since the bag should be your filter instead of relying on the grain husks to form a filter bed.

interesting. You'd think channeling would hurt the efficiency as the grist thickens near the end of each sparge...guess it's not a huge deal

I started putting a bag into my cooler mash tun when I did wheat-heavy recipes after a stuck sparge and it works great for that. I did a 5G recipe with 10lbs wheat double-ground, flowed like a champ.

I am using my existing manifold, and just drop the bag over it. I do that because the bag is a really tight fit around the top of my (round) cooler, and tends to pop off, so I wanted double protection in case the bag slipped down into the mash. It really works great...unbelievable. I get the same efficiencies...mid 70's although I don't obsess about that. The thing this has over BIAB (opinion only) if you already have a cooler tun, you don't have to try and lift heavy bags of wet grain and squeeze them and all that. It's more equipment but works great. The bag makes cleanup a little easier too, but not much. I don't use it every time, just for wheat.

[EDIT] and I would add that since I have a 5G igloo mash tun, I have always just inverted it over a 5G bucket with a trash liner to dump the grains out. I do the same when the bag is in there. So all in all it does not help me with cleanup but I see it could be helpful.

I wash my voile in the laundry, then hang it to dry. Of course, I rinse as much grain with kitchen sprayer as I can first.

I do the same thing as you as insurance that I don't get a stuck sparge. It only took one time having to empty my mash tun into my boil pot to convince me since I use a copper manifold and it was a nightmare to get it unstuck.

I'm doing this right now with a wheat batch. Another benefit is not having to vorlauf...comes out clean as a whistle.

5 gallon paint strainer bags will be big enough but they might be hard to control in a cooler. Some homebrew stores, online or regular, may have what you want or you could sew your own from voille curtain material.

I mash in my turkey fryer with a paint strainer bag and the ones I bought that have the elastic top stretch over the rim and stay there nicely. I could use the ones I bought that have no elastic by using some kind of clip but I think I will just use them for hop strainers instead as the bags are cheap enough to be worth re-purposing.

I have a 10 gallon round cooler as a mash tun. It has a SS braid manifold. I had been using Deathbrewer's stovetop all grain method for quite a while. However, I live in the Midwest and we are the land of temperature extremes. I found it troublesome to keep my mash temperature steady. When I had the chance to pick up this tun for $25 on craigslist, I jumped on it!

I use a "jumbo coarse bag" often used in winemaking to line the tun. Works well for me. I do not have a grain crusher, so I depend on the store to crush. If I get my grain from my favorite place, I average around 72-75% efficiency. I'm happy with that number. Maybe someday I'll start crushing my grain and either cut back on the quantities or recalibrate and go no sparge.

I like the predictability of the insulated tun, ability to squeeze the bag, and ease of cleanup.

Cheers

I use grain bag in the MT which allows for a finer crush at .39 for me. I get 85% consistently. I do one batch sparge then dunk the bag some in my remaining water volume in the kettle. That gets quite a bit of sugar out also. Last time i measured 1.016 in the dunk sparge water, but of course that depends on how much grain you have and the volume of water. Mine was around 9lbs and maybe 3 gallons?
