Brewhouses are the core equipment enabling commercial beer production. This guide covers key considerations around 3.5 barrel brewhouse systems including configurations, sizing, layout, customization, installation, maintenance and more to inform brewery buyers, designers and technicians.
3.5 BBL Brewhouse Overview
A 3.5 barrel (BBL) brewhouse system enables small-scale commercial beer production, typically brewing 1-2 batches per day. Key components include:
Mash Tun – Mixes hot liquor with crushed grains to extract sugars and flavors
Kettle – Boils sweet liquid (wort) with hops to impart bitterness
Whirlpool – Settles out solids post-boil before fermentation
Control System – Automates movement of fluids, heating and monitoring
Properly integrating a 3.5 BBL system allows efficient brewing best leveraging the brewhouse capacity. This guide covers types, sizing, layout, customization, pricing, operation, maintenance and comparisons around 3.5 BBL configurations to inform brewery planning.
Types of 3.5 BBL Brewhouse Systems
Both manual and automated systems suit 3.5 BBL commercial needs:
|Requires transferring fluids by gravity flow or pumping. More labor.
|Programmable controls move liquids between vessels. Less labor.

While automated systems require higher investment, the reduction in manual labor and increased consistency can provide rapid payback in optimized brewing operations.
Sizing Considerations for 3.5 BBL Brewhouses
When developing a production brewhouse, properly sizing vessels enables:
- Mash Efficiency – Appropriate liquor-to-grain ratios during mashing
- Future Expansion – Adding fermenters and infrastructure without brewhouse bottlenecks
- Peak Flow Rates – Prevent overflow with vessels sized above peak flow volumes
- Brew Length Flexibility – Occasional larger or smaller batch capabilities
For a 3.5 BBL mash tun, recommended configurations include:
- 5-7 BBL kettles – Allow mashing in entire volume, boil vigor control
- 3-5 BBL whirlpools – Settle out solids post-boil before transferring clean wort to fermenters
This infrastructure supports mashing and boiling 3-4 BBL batches for fermentation flexibility.
Key Components of a 3.5 BBL Brewhouse System
Constructed from food-grade stainless steel, key elements of a 3.5 BBL brewhouse incorporate:
Mash Tun – Mixes grist and hot liquor to convert starches into fermentable sugars. Customizable for infusion or multi-step mashing.
Lauter Tun – Separates sweet wort from spent grains after mashing. Often integrated with mash tun.
Kettle – Boils wort bittering hops and coagulating proteins. Sized above mash tun volume.
Whirlpool – Swirls post-boil wort settling hops and proteins before transfer.
Piping – Food-grade piping routes fluids via pumps or gravity. Sloped for drainage.
Control Panel – Touchscreen orchestrates equipment, temperatures and fluid movement automatically.
These vessels and connections enable moving sweet wort through the complete mashing, lautering and wort production process essential for beer brewing.
Popular Brewhouse Configuration Layouts
Two typical equipment layouts used for 3.5 BBL brewhouse systems include:
Linear Layout – Mash tun feeds lauter tun feeding the kettle and finally whirlpool linearly. Requires more floorspace but simplifies gravity flow.
Compact Layout – Equipment stacked vertically with pumps routing fluid between vessels to minimize footprint. More complex.
Compact layouts save significant floorspace using vertical space. This enables installing into existing structures. Linear arrangements provide simpler gravity flow paths avoiding pumping. Brewers choose layouts balancing space constraints, expandability plans, fluid routing complexity and equipment cost.
Customization Options for 3.5 BBL Brewhouses
While offering turnkey solutions, many 3.5 BBL brewhouse manufacturers provide extensive customization around:
- Mash tun configuration – Infusion or multi-step mashing
- Advanced lautering – Programmable variable flow control valves
- Kettle features – Autohop additions or live steam injections
- Control system – Degree of recipe programmability and automation
- Grain handling – Conveyor, silo and milling systems
- Process monitoring – Gravity, pH and mass flow measurement sensors
- Heat exchange integration – Linking with existing boiler rooms or cooling
- Effluent management – Spent grains and wastewater routing infrastructure
- Fermentation interfaces – Smooth transfers, cooling and pitching
- Brewery management software – Inventory, production planning and analysis
This flexibility around equipment and functionality allows matching brewhouses precisely to brewing process objectives.
Comparing 3.5 BBL Brewhouse Manufacturers
Many brewing equipment manufacturers offer 3.5 BBL brewhouse solutions. When comparing providers, key criteria include:
- Customization Range – Assess flexibility around vessels, automation and auxiliary systems

Operating and Maintaining 3.5 BBL Brewhouse Systems
To sustain performance, brewhouses require stringent brewing protocols and scheduled maintenance:
Brewing SOPs – Consistent mash profiles, transfer timings, cleaning and sanitation procedures optimize quality and yield.
Preventative Maintenance – Regularly inspect fittings, seals, sensors and motors. Replace worn parts proactively.
Tuning – Monitor all batches for precision improvement. Adjust profiles, temperatures and flow rates to perfect recipes.
CIP Automation – Programmed cleaning-in-place cycles save hours cleaning while eliminating operator errors.
Contingency Planning – Create redundancy plans for potential equipment failures, delays or brewer absence.
Making checklists and schedules for detailed brewing SOPs plus preventative maintenance enables smooth operations, top quality and maximum uptime.

The Brewing Process on a 3.5 BBL Brewhouse System
While configurations vary, the typical brewing process on a 3.5 BBL brewhouse comprises:
Milling – Crack grains in rotational mill for access during mashing
Mashing – Mix grains with hot liquor at set temperatures to convert starches into fermentable sugars
Lautering – Drain sweet liquid then spray grains with hot sparge liquor to rinse sugars
Boiling – Mix wort with hops boiling over 60-90 minutes extracting flavors and bitterness
Whirlpooling – Swirl hot wort settling solids before transferring clear liquid
Cooling – Rapidly chill boiling wort avoiding contamination before pitching yeast
Fermenting – Transfer into fermenters where yeast converts sugars into alcohol
Filtration – Filter to clarify before kegging, canning or bottling finished beer
Packaging – Fill serving containers for shipping and sales
Automating temperature controls, pumps, valves and sensors allows a single brewer to orchestrate this entire process from grain to package beer.

|Lower equipment expense
|Higher infrastructure investment
|Multiple brewers needed
|Single brewer can manage
|Shorter to start brewing
|Longer integrating automation
|Simpler mechanical upkeep
|Varies batch to batch
