Brew 5–10 gallon batches in one compact stainless steel system
The BREWHA Medium BIAC® is a complete all-in-one electric brewing system designed for finished beer batches of approximately 20–40 L / 5–10 US gallons. It brings mashing, boiling, chilling, fermentation, conditioning and serving together around one stainless steel conical vessel.
It is ideally suited to serious home brewers, recipe development, pilot brewing, brewing education, small-batch specialty production and brewers who want to learn on the same BIAC platform used in larger commercial BREWHA systems.
One vessel. Five brewing stages.
Traditional brewing systems transfer wort between separate mash, boil and fermentation vessels. The patented BREWHA BIAC process uses a removable Mash Colander® to mash above the conical fermenter, allowing the wort to be boiled and fermented in the same vessel.
Because wort is boiled in the vessel used for fermentation, the heat of the boil sanitizes its internal product-contact surfaces. This eliminates the separate chemical sanitation step normally required after transferring wort into a traditional fermenter. Routine cleaning and appropriate equipment maintenance are still required.
Why brewers choose the Medium BIAC
- Compact footprint: combine multiple brewing stages around one vessel.
- Flexible batch sizes: produce approximately 20–40 L / 5–10 US gallons of finished beer.
- Fewer transfers: reduce handling between mashing, boiling and fermentation.
- Electric operation: brew indoors without an open-flame heat source.
- Pressure-capable vessel: ferment, condition and serve from the conical fermenter when operated within its rated limits.
- Removable Mash Colander: lift the grain from the wort before boiling.
- Commercial-quality construction: develop recipes and operating practices on the same BIAC platform used at commercial scale.
- Expandable production: add compatible fermenters and reuse the system’s Mash Colander, pump and controller as your brewing schedule allows.
Choose the accessory package that fits your brewery
Both accessory-package options are built around the same Medium BIAC brewing platform. Choose the Basic Accessories Kit if you already own suitable supporting hardware, or select the Complete Accessories Kit for a more comprehensive brewing setup.

Medium BIAC brewing system specifications
Brewing capacity
- Recommended finished-beer volume: 20–40 L / 5–10 US gal
- Maximum grain bill: 11 kg / 25 lb
- Maximum pre-boil volume: 54 L / 14 US gal
- Total fermenter volume: 60 L / 16 US gal
Important: The 60 L / 16 US gallon figure is the total vessel volume, not the recommended beer-batch volume. Recommended finished-beer batches are approximately 20–40 L / 5–10 US gallons.
Dimensions and installation clearance
- Fermenter dimensions: 110 cm / 43 in high with the lid removed and 50 cm / 20 in outside diameter
- Fermenter with Mash Colander: 162 cm / 64 in high
- Recommended ceiling height: 224 cm / 88 in
- Recommended ceiling height with an electric hoist: 244 cm / 96 in
Allow additional clearance for the lid, blow-off hose and surrounding working area. Confirm that the brewing space provides enough ceiling clearance to lift and remove the loaded Mash Colander safely.
Electrical requirements
- Electrical supply: 240 V, single phase
- Maximum brewing-system draw: 20 A
- Heating power: 4.5 kW
- Controller connection: NEMA 14-30 receptacle on an appropriately installed 30 A circuit
Electrical service, receptacles and installation requirements vary by location. Have a qualified electrician confirm your available voltage, circuit capacity and applicable local requirements before ordering or installing the system.
Pressure and shipping
- Vessel pressure rating: 14.9 psi
- Jacket pressure rating: 7 psi
- Approximate complete-system shipping weight: 175 kg / 385 lb
- Additional shipping weight with chiller: approximately 55 kg / 120 lb
Shipping weights are approximate and may vary with the selected accessory package, optional equipment, packaging and final shipment configuration. Confirm the final freight weight with BREWHA before ordering.
For complete capacity, water, ventilation and installation information, review the BREWHA BIAC specifications.

Expand production as your brewing plans grow
Additional BREWHA 5-in-1 fermenters with heaters can be added as production requirements grow. The system’s Mash Colander, pump and power controller can be used with compatible additional fermenters according to your brewing schedule.
This allows you to increase fermentation capacity without purchasing another complete set of shared brewing hardware for every vessel.

Is the 10-gallon BIAC the right size?
The best brewing-system size depends on your target batch volume, brewing frequency, available ceiling height, electrical service and plans for future expansion.
