Scaling flavor is hard: the wrong tank delays batches, dulls aroma, and drains cash. Choose wisely, and your beer tastes brighter and ships faster.
A beer brewing tank is a sanitary, pressure-rated schip used to transform wort into beer and prepare it for service. Core types include maischketel, ketel, fermentor (vaak conische fermentor), bruistank (also called heldere tank), lagering and serving tanks. Each tank handles a phase—mashing, boiling, primary fermentation, maturation, clarification, and packaging. The right shapes and sizes (e.g., 10 bbl) and fittings let brewers pressurize, carbonaat, and hold temperature precisely for consistent results.
What does a beer brewing tank actually do in a brewhouse?
A modern brewhouse runs on purpose-built tank stages. In hot side steps, the mash tun and ketel create wort. On the cold side, a fermentor turns sugars into alcohol and aroma; a polishing tank such as a bruistank clarifies, lets you carbonaat, and readies beer for packaging. One correctly sized beer tank linked to chilling and controls can stabilize throughput and boost quality.

Mash tun and brew kettles: how does hot-side work prepare perfect wort?
Hot-side work happens in two stainless tank workhorses: the maischketel En brew kettles. De giststarter converts grain starches to sugar; a lauter bed clarifies the sweet liquid. Next, the ketel boils to sterilize, drive off volatiles, and is where hops isomerize. This prepares wort with stable bitterness and a bright malt profile for the cold side.
A small hospitality concept might run a 3–7 bbl brewhouse; a production site might stage 20–60 bbl vessels with steam from a central ketel. Thermal management (rakes, jackets) and the way you isoleren the shell keep extraction predictable. If you’re evaluating your first pro setup, compare heat sources, vessel geometry, and automation across pilot to production lines: See commercial system options.
Fermenter basics: why a conical fermenter is the cold-side MVP
A fermentor is where magic happens. The cylindrical body with a 60° cone concentrates yeast and trub, so a conische fermentor lets you dump solids while keeping beer clean. Most breweries run jacketed, CIP-ready tank shells to hold precise temperature through primary fermentation En rijping. You’ll use only one gist strain at a time here, so sanitation matters.
For scale, you’ll see 5, 10, 20 bbl models—right-sizing the tank reduces oxygen pickup and holds backpressure safely. Look for sanitary ports, a PRV, carb stone options, and a single fitting standard for hoses and pumps. If you’re comparing cone angles and racking arm designs, check pro-grade models with glycol jackets and clean-in-place spray balls: Compare beer fermenter tank options.
Brite tank (a.k.a. bright tank): how to polish beer and control the carbonation
After gistingde bruistank (sometimes written heldere tank) clarifies and carbonates. It’s a pressure-capable tank (think “final-stop” schip) where you chill, settle haze, and control the carbonation with measured kooldioxide. You’ll gently pressurize the headspace and carbonaat through a diffusion stone while reading a gauge.
For stable cold-side performance, a jacketed brite—yes, a jacketed brite design—ties into a chiller via glycol piping. That loop keeps beer cold and consistent from batch to batch. If you need faster turns, a sight glass and carb stone speed up clarity checks and dialing in volumes of CO₂. Learn how pro tanks integrate carb stones and racking arms: Bright tank setup and fermentation accessories.
“Clarity, stability, and fine bubbles are not accidents; they’re engineered in the brite.”
Draft service and packaging: linking brite to kegs and lines
Polished beer moves from the polishing tank into packages. Lines feed a canner, bottle filler, or a vat washer/filler. Head pressure, flow control, and temperature alignment prevent foaming while preserving aroma. In taproom models, the brite can feed a service tank in a cold room, or go straight to packaging if the floor plan is compact.
If your concept prioritizes draft speed and low oxygen, consider integrating semi-automatic fillers and ergonomic rinse/blow cycles. Here’s a real-world place to start: Beer keg filling machine integration for packaging.
Lagering tanks vs horizontal lagering tanks: when do you choose which?
Lagering tanks extend conditioning, allow sulfur to fade, and refine mouthfeel. Many breweries stage a separate conditioning tank to decouple fermentation throughput from polish time. Traditional German programs run colder and longer to refine sulfur and diacetyl for crisp finishes in ambachtelijk bier.
When space and foam stability are priorities, horizontal lagering tanks shine. Their horizontal orientation gives a large surface area for yeast to drop out and speeds cold clarification—often with tighter natural carbonation. Some sites also practice horizontal lagering for hybrids and seasonal lagers to improve colloidal stability. Thinking about a side program? Compare micro-scale options: Micro brewery equipment for extended conditioning.
Utilities: glycol piping, cold liquor, and how to insulate for efficiency
Every cold-side tank relies on steady chilling. Jacket channels circulate a propylene glycol blend from a chiller; properly sized headers and glycol piping keep delta-T tight across several tanks online at once. Flow meters, isolation valves, and balancing ensure even jackets.
On the hot-side, a cold liquor tank helps you knock out quickly while saving water. Match heat-exchanger plate area to peak turn rates so your tank cooldown hits targets. Properly isoleren shell and cone to reduce energy loss and stabilize ferment temps. Planning a small program or pilot cellar? See how small-batch systems bundle utilities efficiently: Small brewery equipment and utilities.
Sizing your tank: bbl capacity, shapes and sizes, unitank options
Capacity strategy starts with sales math. For a 10 bbl brew length, two fermenters at 20 bbl plus one polishing tank is a common cadence. Consider skids, access for CIP, and catwalk safety. Many producers choose a eenheidsbank to handle both fermentation and carbonation in a single pressure-capable tank.
Material and finish matter, too. Food-grade roestvrij staal (commonly 304) resists caustic and acid cycles and is eenvoudig te reinigen. If space is tight, a stackable cellar or taller cone geometry can double turns per square meter. Ready to map cone angles, jackets, and port heights? Start with pilot specs here: Nano brewery equipment and cellar sizing.
Materials, fittings, and sanitary design: safety in the brewing industry
Sanitary design keeps oxygen low and keeps operators safe. Polished welds, slope-to-drain floors, and shadowless CIP coverage inside the tank reduce harbor points. A single tri-clamp fitting standard simplifies spares. PRVs protect the tank during cleaning and heat cycles, essential in commercieel brouwen.
For durability, stainless interiors resist repeated CIP and acid passes. Clear SOPs and lockout on pumps help every brouwer work confidently. If your program spans beer, cider, or spirits, coordinate shared utilities and skids—look at flexible skid layouts that cross over into spirits: Commercial distillery equipment for hybrid cellars.
Cost, timeline, and turnkey delivery for a craft beverage launch
A growth-ready cellar balances batch targets, cash flow, and lead time. When scoping, request a bedrijfsklaar package: brewhouse, fermentatietanks, bruistank, controls, utility skids, and documentation. Make sure your vendor can custom build ports and valves to fit your floor plan and fire code—and can service globally.
If you’re branching into alternative SKUs such as kombucha, soda, or RTD, ask for cross-compatible ports, stones, and temperature controls so your tank farm supports a broader craft beverage mix. Here’s a practical primer on crossover systems: Kombucha brewing vessel and utilities.

Case study: a 15 bbl brewpub adds capacity without adding real estate
Setting: A busy kitchen-forward brewpub needed +30% volume, no new footprint.
Move: They swapped an older polishing tank for a larger pressure-rated bruistank, added one 30 bbl conische fermentor, and re-routed glycol piping to balance cooling on peak days.
Result: Two more turns per week, smoother package days, and tighter foam control from brite. Staff cited faster CIP and fewer spares thanks to unified ports and clamps.
FAQs
What’s the difference between a fermenter and a brite tank?
A fermentor performs primary fermentation and early conditioning; a bruistank clarifies and carbonates before packaging. The brite is pressure-rated for fine control when you carbonaat and stabilize aroma.
Do I need a separate lagering tank?
Not always. A eenheidsbank can handle conditioning, but dedicated lagering tanks (vooral horizontal lagering tanks) improve clarity and sulfur reduction on long programs.
How do I size the cellar for seasonality?
Start with weekly sales and brew length (e.g., 10 bbl). Add one extra tank for peak months to keep the schedule flexible. Larger polishing capacity helps you move fast between styles.
Is 304 stainless steel okay for beer?
Yes—polished roestvrij staal (304) is industry standard. It’s robust, sanitary, and eenvoudig te reinigen, with long gasket life under CIP.
Can one tank do it all?
A eenheidsbank can ferment, hold pressure, and carbonate. It’s a versatile tank for compact sites, especially when paired with the right carb stone and PRV.
What pressures are typical when carbonating?
Use head pressure consistent with your temperature and target volumes of CO₂. You’ll pressurize carefully with kooldioxide and monitor gauges to avoid over-carbing.
