BIAB Recirculation Brew Bag 400 µm

The "Brew Bag" is a simple and very useful mash bag for home brewers who want to start with mash brews according to the popular "Brew in a Bag" method. This allows you to perform whole grain brewing while keeping your equipment costs minimal and your brewery as simple as possible! I am personally a big fan of this method and use it about half the time when brewing. It's a perfect way for beginning and experienced homebrewers alike to KISS (keep it simple, stupid)!

The standard Brew Bags have a 200 micron mesh size and are not suitable when recirculating with a pump. These bags with 400 micron mesh size work perfectly when you want to add a pump to your mash kettle! They are a bit less flexible than the standard brew bags but we had them specially sized to fit our 38L kettles so they fit well. The bag height is optimized for use with our the tall false bottom stand in our 38L kettles, with about 8cm extra which folds over the top of the kettle.

Choose your kettle size from the options above. 

• Material: Food safe polyester
• Mesh Size: 400 micron

Do not mash as finely as you would when using the standard 200 micron mesh bags. I recommend a grain mill gap not under 1mm. The standard crush you get from your homebrew shop is probably perfect.

These grain bags also make a great addition to our pumped 2V and 3V systems. they make grain removal super easy: when finished mashing, just pull out the bag, dispose of the grain, rinse out the bag. No more picking grains out of your false bottom! They also ensure a perfectly clean wort in the kettle with no grain husk.
 
Note: If you are not pumping and want to use a finer crush, choose the 200 micron brew bags.
