Brewery Tanks for Craft Brewers

Craft beer lovers, industry starters, or just curious minds—ever wondered what those massive, shiny tanks behind the glass in your favorite brewery are all about?

Types of Brewery Tanks

Alright, picture this: a brewery is like a kitchen, and the tanks are your ovens, pots, and pans. Every step in the brewing process has its own special vessel. Here are the main players you need to know:

First up, the Mash Tun. This is where the milled malt (grains) meets hot water. Think of it as making a giant batch of oatmeal—enzymes break down the starches into sugars. It’s the foundation of your beer.

Next is the Lauter Tun. Here, you separate the sweet liquid (wort) from the spent grain. It’s basically the brewery’s version of straining pasta.

Now enters the Brew Kettle (aka Boil Kettle). This tank brings the wort to a boil and is where hops are added. This part gives your beer its bitterness, aroma, and flavor punch.

Then we move to the Whirlpool Tank. After boiling, the liquid is swirled here to separate out the solid hop particles. Think of it like the spin cycle in your washing machine.

The Fermenter is next. This is where the magic happens. Yeast is added, and fermentation begins. This is the tank where your wort becomes actual beer.

Finally, there’s the Brite Tank. It’s where the beer goes to chill, carbonate, and clarify before packaging. You could call it the beer’s final beauty rest before the spotlight.

Material Introduction of Brewery Tanks

When it comes to materials, it’s not just about what looks shiny. It’s about what holds up under pressure (literally) and doesn’t mess with the taste.

The most common material for brewery tanks is Stainless Steel, particularly grades 304 and 316. These grades offer high resistance to corrosion, are easy to clean, and don’t react with acidic ingredients in beer. Stainless steel is also super durable and can last decades if properly maintained.

Some smaller or traditional breweries might use copper, mostly for aesthetic or historical reasons. Copper heats up faster but is harder to maintain and more prone to chemical reactions if not properly lined.

Plastic and glass carboys might be used at the homebrew level, but they don’t stand up to the demands of commercial brewing.

So when you hear a brewer talk about their “stainless setup,” now you know why that matters!

How to Choose the Right Brewery Tank

Choosing a brewery tank isn’t just about size. It’s like buying a car—sure, you want horsepower, but you also care about fuel efficiency, comfort, and how it handles turns.

First, think about your production goals. Are you making 5 barrels a week or 50? Your output determines the tank capacity you need. A microbrewery might use 5-10 barrel fermenters, while regional operations use tanks upwards of 60 barrels.

Next up is space. Are you brewing in a warehouse or a cozy downtown garage? Measure twice, buy once. Height, door width, and even ceiling clearance matter.

Then there’s process compatibility. Some systems are single-vessel, but others split the stages among multiple tanks. If you want maximum control over taste, separate vessels are usually better.

Don’t forget about expansion. It’s way easier to scale up if your infrastructure (like glycol cooling systems) is built to handle more tanks later.

And of course, think about budget versus quality. Imported tanks from China might be cheaper, but domestic tanks often come with better support, warranties, and build standards.

Key Features of Brewery Tanks

Here’s a quick look at the critical features to keep in mind when comparing brewery tanks:

Feature	Description	Why It Matters
Material	Usually 304/316 stainless steel	Durable, corrosion-resistant, easy to clean
Capacity	Ranges from 1 barrel to 120+ barrels	Impacts batch size and scalability
Pressure Rating	Varies by tank type; fermenters are often pressurized	Important for carbonation and safety
Cooling Jacket	Glycol or water jacket surrounds the tank	Maintains precise fermentation temps
Insulation	Polyurethane foam is common	Helps retain temp and saves energy
Manway Access	Side or top hatches	Makes cleaning and inspection easier

Agitators or Rakes	Especially in mash tuns	Improves mix and prevents scorching
Valves and Fittings	Sample ports, blow-off valves, etc.	Essential for monitoring and safety

Cost Factors of Brewery Tanks

So, how much are we talking for a single tank? Well, it depends. The cost of brewery tanks varies based on size, features, materials, and origin.

On average:

• A 5-barrel fermenter might run around $3,000 – $6,000.
• A 15-barrel brite tank could go for $7,000 – $12,000.
• Complete brewhouses (multiple tanks) range from $50,000 to $300,000+ depending on capacity and automation.

Other cost influencers include:

• Customizations: like special insulation or polished finishes
• Shipping: tanks are heavy, bulky, and need careful handling
• Installation: connecting pipes, glycol systems, and electrical

While you might save upfront with imported equipment, don’t forget to factor in after-sale support, potential delays, and quality concerns.

Maintenance Suggestions for Brewery Tanks

Treat your tanks well, and they’ll treat your beer even better. Maintenance isn’t glamorous, but it’s non-negotiable.

Here’s the basic maintenance recipe:

• Clean thoroughly after each use using CIP (Clean-in-Place) systems. Leftover sugars or yeast can turn into bacteria breeding grounds.
• Inspect seals and gaskets regularly. These little parts can cause big leaks if worn out.
• Check for pitting or corrosion, especially in weld seams.
• Monitor temperature sensors and pressure gauges for accuracy.
• Flush glycol jackets occasionally to prevent clogs and ensure even cooling.

Some breweries schedule a monthly deep clean where tanks are manually inspected, and parts are replaced proactively.

Where to Buy Brewery Tanks

Shopping for brewery tanks is part research project, part relationship-building exercise.

Reputable manufacturers include:

• Ss Brewtech (USA)
• Blichmann Engineering (USA)
• JV Northwest (USA)
• DEGONG Brewery Equipment (China)
• NFE Machinery (China)

Many breweries work with integrators who design full systems and act as a one-stop shop. This can save you headaches when troubleshooting later.

Local dealers might charge more, but the peace of mind (and onsite service) can be worth it. Also check industry trade shows and used equipment auctions.

Additional FAQs About Brewery Tanks for Craft Brewers (2025)

1) What pressure rating should I choose for fermenters and brite tanks?
For most craft breweries, 1 bar/15 psi working pressure supports spunding, carbonation, and closed transfers. Ensure PRVs are ASME-rated and sized for vessel volume.

2) What interior finish improves cleanability and micro risk?
Specify ≤0.8 μm (32 Ra) mechanical polish on product-contact surfaces; electropolish is increasingly adopted on cold-side vessels to reduce biofilm formation and shorten CIP cycles.

3) How do I size the glycol chiller for my cellar?
As a rule of thumb, allocate 1.0–1.5 tons of refrigeration per actively fermenting 10 bbl fermenter equivalent; 0.5–0.8 tons per brite/storage tank. Validate with OEM heat-load data and local ambient conditions.

4) How can I minimize dissolved oxygen during transfers?
Use CO2-purged hoses and vessels, closed transfers FV→BBT→package, cap-on-foam at filler, and verify with inline or handheld DO measurements on brite/package.

5) Are horizontal tanks worth it for lagers in small breweries?
Yes. Horizontal lagering tanks increase surface area-to-depth ratio, speeding clarification and freeing vertical fermenters for primary fermentation, improving throughput.

2025 Industry Trends for Brewery Tanks

• Unitank dominance: Pressure-rated cylindroconical tanks enable fermentation, conditioning, and carbonation in one vessel, reducing transfers and O2 pickup.
