Perfect micron for making a proper basin of Kava. This is the bag you're looking for. Granted it's a bit larger than needed but works well for this purpose, without too much product permeating through the bag.

Used these to make mozzarella cheese. Unlike traditional cheesecloth this was able to do the job for me and properly separate the curds from the whey.

We love and drink A LOT of cold brew, so I've rigged up a large-batch system making 3 gallons at a time (using a 3-min hot bloom method). These bags are perfect for the process. They stand up well to the initial heat, empty out and clean easily, and result in the least amount of residual grounds compared with every other metal or bag filter that I've previously tried. I could not be happier with the results!

These mesh bags appear to be high quality although I have not used them yet. They are also a good size for small batch fruit wines i plan to make and are a reasonable price when compared to other similar bags.

Forget anything you have read about using cheesecloth or coffee filter to strain yogurt into Greek yogurt. This is the bag you need. The dimensions may appear to be too large, but in use, this just the right size for one gallon of yogurt.

Two tips: First turn the bag inside out so that the sewed seams are to the outside. This will make cleaning a lot easier. Second, wet the bag with water. This will help in the draining.
Then drape this bag over a colander and place it over a suitable pot to catch the whey.

Pour your yogurt in and let it drain.

The 75 micron holes make draining yogurt easy and fool-proof. The whey comes out practically clear so there is no wasted yogurt. Draining yogurt about 11-12 hours makes for a nice consistency. I once accidentally left one batch draining for over 24 hours. I thought I would have turned my yogurt into cream cheese, but everything came out great.

When the drain time is over, just lift the full bag and dump it into a large bowel. The yogurt simply falls out. Keeping the seams on the outside prevents any thing sticking. A few whips with a whisk and the yogurt is done.

Cleaning these bags is a snap. The large size does make for a cumbersome clean up but it is really quite easy. Turn the bag inside out so that the seams are inside and the side that was touching the yogurt is on the outside. Simply rinse the bag with your hand inside. It really rinses out well. The yogurt left-overs really do slide off the bag material. Clean up takes about three minutes. Then just hang the bag up and it will dry quickly.

I was struggling with and ruined several yogurt batches until I tried this bag. Don't buy a smaller bag like the 12x12. It was much more cumbersome to use as it just barely held one gallon. This this larger one and you wont' have any worries about anything spilling.

Package came with two but honestly, I don't see this bag wearing out any time soon. Three batches of yogurt later and the bag does not have a blemish. .

Seller shipped fast and the bags arrived clean and undamaged.

I may not need to buy any replacements for a while, but if I do need a replacement, I will gladly order from the same supplier.
