This 'mash tun with a porous bottom' is part of the complete home brewing and commercial brewing system for making beer, and allows mashing directly in the jacketed conical fermenter^TM, saving you space, time and money. Having completed the mash, the colander is lifted from the top of the fermenter, removing all the grain with it while the wort drains out the bottom into the fermenter where it is ready for boiling. The Mash Colander^TM brings all the benefits of a Brew In A Bag (BIAB) style brewing without any of the limitations. The Mash Colander^TM is included as part of the All-in-1 BIAC^TM system.

An essential part of the BIAC method of brewing, BREWHA's Mash Colander allows you to mash directly in the stainless conical fermenters as well as having the capability to vorlauf by recirculating out the bottom of the BIAC fermenter and back into the system through the port at the top of the colander. The colander functions just like a mash tun with the perforated bottom of the colander serving as the mash screen (wedge wire bottoms also available). It works better than a brew-in-a-bag (BIAB) system since grain in the colander can form a proper grain bed, giving you best filtering for better clarity in your wort and the solid walls of the colander allow you to circulate wort through your grain bed giving you consistent temperature control throughout your grain bed and best mash efficiency possible. When mashing is completed, raise the colander out of the fermenter for draining and rinsing your grain. (When brewing with the Medium, Large, 1.5BBL to 15BBL BIACs—raising the colander can be easily accomplished by using a portable hoist as shown on this page.)

Your brewing will never be simpler, more sanitary, more enjoyable, more space efficient or provide better tasting results.

BREWHA's Mash Colander brings all of the benefits of the BIAB (Brew In A Bag) system including: 

1. requiring less equipment 
2. using less space
3. taking less time on brew day
4. costing less money

And it brings additional features including:

1. allowing brewing of larger and higher gravity batches since the solid stainless steel won't break like a bag will
2. being easy to step mash. Since the BIAC operates like a regular mash tun, circulating the wort through it is easy, and you can heat the wort up as it circulate in a RIMS type system using the heating element under the Mash Colander in the stainless conical fermenters. By using the digital temperature controller to regulate power to the electric immersion stainless heating element you can heat wort as it circulates down through the Mash Colander, past the element and back to the top of mash colander. The circulation also ensures that the temperature is evenly distributed through the Mash Colander
3. brewing 'extreme' beers as you can keep the same water to grist ratios as in a conventional mash tun
4. clarifying wort because a proper grain filter bed can be formed
5. achieving as high mash efficiency as any mash tun as it can operate at same water:grist ratios, has the same manner of recirculation causing greatest interaction of enzymes and carbohydrates, and can be sparged as it is withdrawn from the BIAC fermenter

Mash Colander includes:

A. three 1.5" sanitary wing-nut tri-clamps
B. three 1.5" sanitary gaskets
C. two 1.5" sanitary tri-clamp ferrules
D. one 1/2" hose barb attached to 1.5" sanitary tri-clamp caps
E. one 1.5" sanitary valves (full disassembly for cleaning)
F. one high efficiency mash screen (the bottom of the vessel)
G. one lid and raised lid handle
