Today we shipped a customized 1,000L direct fired brewhouse system to a craft brewery in Australia. It's a project worth writing about—not because a shipment is unusual for us, but because the customer's choice of direct fire heating runs against the industry's steady drift toward electric and steam, and their reasoning is instructive for anyone weighing the same decision.
This post covers why direct fire made sense for this brewery, how we configured the system, and the manufacturing details that matter when you're buying a gas-fired brewhouse from overseas.
Australia has one of the most competitive craft beer scenes in the world, and breweries here tend to know exactly what they want from their equipment. This customer was clear from the first conversation: they wanted a vigorous, reliable rolling boil and fast heat-up on brew days, and they had access to affordable natural gas at their site.
Those two conditions are what make direct fire a rational choice rather than a nostalgic one. Direct fire uses gas burners beneath the kettle to heat the wort directly, which delivers a fast temperature rise and a strong, rolling boil—useful for driving off unwanted compounds and achieving good hot break. Where local gas is cheaper than electricity, the operating economics can also favor gas over electric heating.
It's worth being honest about the trade-off, because I gave the customer the same caution I'd give anyone: direct fire heat distribution is less even than steam, and temperature control takes more attention at scale. For this brewery—1,000L batches, gas on-site, and a preference for a strong boil—the trade-off worked in their favor. For a brewery in a location with expensive gas or strict open-flame permitting, the answer could easily go the other way.
We built this system around the customer's specific brew-day workflow and site layout rather than shipping a fixed catalog unit. The core configuration:
Direct fire natural gas heating for rapid heat-up and a strong rolling boil
Professional burner controller for safe, repeatable firing
Exhaust chimney sized for proper ventilation of combustion gases
High-performance insulation to improve heat retention and reduce gas consumption
Food-grade stainless steel construction throughout for hygiene and durability
Customizable vessel combination matched to the brewery's throughput goals
Flexible automation options for the customer's operating preference
For a 1,000L brewhouse, heating performance is one of the biggest factors in brew-day length. A configuration that heats and boils efficiently lets a brewery run more batches per day and hold a consistent boil—which directly affects wort quality and batch-to-batch consistency.
The brewhouse is the heart of a brewery, and its build quality shows up in every batch for years. For a direct fired system, the burner interface and combustion-related components need particular attention alongside standard tank fabrication.
Manufacturing Focus | Why It Matters |
Stainless steel vessel fabrication | Corrosion resistance and food-safe wort contact surfaces |
Heating interface & burner installation | Safe, even flame contact and reliable ignition |
Welding quality | Sanitary welds prevent contamination and leaks under thermal stress |
Internal & external polishing | Smooth surfaces support effective CIP cleaning |
Insulation & heat retention | Lower gas consumption and stable process temperatures |
Pipeline & platform assembly | Safe operator access and correct process flow |
Pre-shipment inspection | Catches issues before the system leaves the factory |
Before packing, the complete system was inspected for workmanship, configuration accuracy, and finish. The point of a thorough factory check is to reduce surprises during installation on the customer's side—problems that are far cheaper to fix in our workshop than after the equipment has crossed an ocean.
A full brewhouse system involves multiple vessels, platforms, and components, and each needs protection for a long sea journey. Poor packing or loading is one of the most common—and most avoidable—causes of arrival damage on large equipment.
Our shipment process for this project included:
Final equipment inspection before packing
Surface protection against scratches and transit damage
Secure packing suited to each component's size and weight
Careful loading for stable transport
Export documentation and shipment coordination
The system departed for Australia on July 20, 2026.
This project used Cassman's Direct Fired Brewhouse System, built for breweries that want strong heating performance, fast boiling, and flexible customization.
The system is available across a range of capacities to match different production goals and site layouts:
Models: CM-500L, CM-1000L, CM-3BBL, CM-5BBL, CM-7BBL, CM-10BBL, and CM-15BBL
Control options: semi-automatic PID control or fully automatic Siemens PLC control
Because no two breweries run the same way, we customize direct fired systems by capacity, vessel layout (2, 3, or 4 vessels), burner type and interface, control system, pumps and pipelines, work platform, heat exchanger, wort oxygenation, connection standards, and voltage requirements.

What is a 1,000L direct fired brewhouse suitable for?
It suits craft and small-to-medium commercial breweries that need reliable batch capacity and strong heating performance. At 1,000L, breweries can run meaningful production volumes while keeping brew days efficient.
What are the advantages of direct fire heating?
Direct fire offers rapid temperature rise, a strong rolling boil, and potentially lower operating cost where local gas is cheaper than electricity. The trade-off is less even heat distribution than steam, so it's best suited to sites with affordable gas and a preference for vigorous boiling.
Can Cassman customize the brewhouse configuration?
Yes. We customize vessel combination, heating method, burner interface, automation level, tank layout, voltage, fittings, and connection standards to match each customer's brewing process and site conditions.
Does the direct fired brewhouse include a burner and exhaust chimney?
Yes. Our direct fired systems can include the burner controller, burner configuration, and an exhaust chimney sized for safe ventilation of combustion gases.
Does Cassman ship brewery equipment to Australia?
Yes. We have exported brewery equipment to Australia and other international markets, with export packing and shipment coordination handled in-house.
