Commercial brewery sizing calculator

What size brewing system do I need?

Work backward from annual production, weekly workload, available floor space and ceiling height to compare BREWHA commercial BIAC brewing systems.

Start the size calculator

Work backward from the brewery you want to operate.

Enter production demand, available equipment area, ceiling height and the brewing schedule you can sustain.

Production + building fit

Calculate the BIAC system size your plan can support.

The calculator checks 1.5, 3, 5, 7 and 15 BBL systems against the same assumptions, then identifies the smallest batch-size option that meets the entered schedule, preliminary equipment-area screen and standard ceiling clearance.

Planning inputsDescribe your production target and available space

Units

1 Production goal

Target annual saleable beer BBL/year Brewing weeks per year Enter 20–52 active production weeks to allow for seasonal schedules and planned downtime. Maximum brew sessions per week Enter 0.5–14 sessions based on the workload your team can consistently sustain. Saleable yield % This reduces nominal batch volume for process, transfer and packaging losses. Use 100% to compare theoretical output with published capacity.

2 Tank cycle

Average weeks in each 5-in-1 Fermenter Include fermentation, conditioning, serving occupancy, cleaning and reset time.

Why this matters

A longer tank cycle requires more fermentors to support the same annual output.

3 Available equipment space

Usable brewing-equipment floor area sq ft Enter the production-equipment zone—not the taproom or entire building. Clear ceiling height ft Measure where the lifting system will operate. Some facilities may support a reduced-clearance lifting arrangement. Contact BREWHA for details.

Ready when you areEnter your plan to compare systems

The result will compare production workload, fermentor count, preliminary equipment area and lifting clearance.

Complete the calculator to compare all five commercial systems.

Planning method: Production uses your saleable-yield assumption. Fermentor count is based on brew sessions per week × the complete tank cycle. The preliminary equipment-area screen gives every fermentor its published diameter plus 24 inches / 0.61 m of total planning width and adds 40 sq ft / 3.7 m² for the shared Mash Colander, pump, controller and working position.

Important: This is an early screening estimate, not a dimensioned brewery layout. It excludes room shape, lifting and staging geometry, chilling, utilities, drains, cleaning, ingredients, packaging, customer areas, service access and code-required clearances. Confirm the result with the Brewery Layout Planner and BIAC Specifications before evaluating a lease or installation.

Read the result in context

Three limits determine the practical brewery size.

Production workload

A smaller batch can meet a large annual target only by increasing brew sessions and fermentor count. Size for a schedule your team can consistently operate.

Fermentation footprint

Tank-cycle time converts weekly brew sessions into occupied vessels. Faster turns reduce tank count; serving directly from a vessel may extend it.

Lifting height

The Mash Colander must lift clear of the fermentor. Ceiling height can rule out a system even when its vessel fits comfortably on the floor.

Common sizing questions

What to decide before ordering a brewing system.

How do I calculate the brewery system size I need?

Begin with realistic annual saleable volume, then divide it by the saleable output per batch and the weeks you expect to brew. Compare the required weekly brew sessions with your staffing plan, and calculate how many fermentors will be occupied during the complete tank cycle.

Should I choose a larger brewhouse or add more fermentors?

A larger system reduces weekly brew sessions but requires more ceiling height and larger vessels. Additional fermentors increase capacity and product variety while reusing the BIAC Mash Colander, pump and main controller. Compare workload, space, capital and sales risk together.

How much floor space should I reserve?

This calculator estimates a compact equipment zone only. A complete brewery also needs working aisles, drainage, chilling, cleaning, ingredients, packaging or serving, utilities and future-growth space. Continue with the brewery layout planner before evaluating a lease.

Can a BREWHA system work with a low ceiling?

Some facilities may support a reduced-clearance lifting arrangement. Contact BREWHA for details. A conditional calculator result is not confirmation that a system fits a specific building.
