The BEST DEAL we've ever offered! We received a shipment of stainless steel mesh brewing filters for BIAB that were missing the infusion tubes that we use for our patented COFI mash system. These filters work great for brew-in-a-bag (BIAB) brewing without the hassle of using mesh bags.
We have these in two sizes, 13" diameter and 15" diameter.
The 13" is $65 and the 15" is $85.
Really, not kidding, this low cost is the cost of 3 mesh bags but will last for 100's of batches and much easier to use.
This is a clearance/closeout item. You will not find a lower price on brewing filters of these sizes. We received these without center infusion tubes, so we are selling them at a deep discount without the center infusion tubes. Our loss is your fortune!
Make sure to select the size you want in the options!
If you fabricate your own center infusion tube, you can enjoy the benefits of our patented (Patent Number US10400200B1) COFI (Center out forced infusion) filter system. Or, you can use these as simple BIAB (Brew in a bag) filter in your kettle instead of using a mesh bag.
They are fabricated from stainless steel with very sturdy fabrication.
This item includes the Filter Body, Cover, Locking Handle (doubles as lift handle), and False Bottom. It DOES NOT INCLUDE THE CENTER INFUSION TUBE!
The center infusion tube which is a tube that has multiple holes drilled to distribute the mash water into the center of the grain bed during mashing (see photo diagram of the concept). There are 1/2" Male Pipe Threads on both ends, one end threads into the false bottom and the other end is used to attach a lifting ring that when lifted causes the false bottom to squeeze the remaining liquid out of the grains. If you want to make your own, the 15 gallon filter version tube is 13 inches long and the 20 gallon filter needs to be 15 inches long.
