What is a commercial brewing system?
A système de brassage commercial is a coordinated set of vessels, pumps, valves, piping, and controls designed for repeatable, food-safe production. It pairs a salle de brassage (where you convert grain to moût) with a cellar (where you ferment and condition beer in a réservoir). Together, they reduce variability and improve throughput so your brasserie can meet demand without sacrificing quality.
The system’s job is simple: remove guesswork. A well-engineered package stabilizes temperatures in the cuve d'empâtage, speeds lautering, moves moût gently, and holds fermentation targets. Sensors, VFDs, and programmable steps help your brasseur hit specs every brew day—so customers get the same pint every time.
How does the brewhouse work (mash, lauter, kettle, whirlpool)?
Think of a brewhouse as a craft kitchen. In the purée, you hydrate milled grain in the cuve d'empâtage to convert starch into sugars. Rakes and jackets keep the bed uniform so you extract evenly. Then you lauter—separating sweet moût from grain while limiting shear. A well-set bed shortens run-off and minimizes astringency.
Next, the bouilloire boils to sterilize, drive off volatiles, and isomerize hops. Flow then enters whirlpool where a tangential inlet cones trub so you can draw bright moût to the échangeur de chaleur. Attention to shear, flow-paths, and tri-clamp seals preserves foam-positive proteins and reduces pick-ups before the cellar.
“Brewhouses that guide temperature profiles and flow consistently make training easier and results more predictable.” — Head brasseur, taproom & distro
Sizing, bbl, and when 3.5 bbl makes sense
Capacity is usually expressed in bbl (barrels; 1 bbl = 31 U.S. gallons). Many startups launch with 3.5 bbl to test market fit, then scale to 7–15 bbl for steady taproom plus wholesale. Your lot size should match tank turns and cold-side capacity, not just hot-side ambition.
Typical capacity ladder
| Brewhouse (bbl) | Ideal Output / Week | Notes |
|---|---|---|
| 3.5 | 1–3 turns | Pilot, nano, festivals, rapid iteration |
| 7 | 2–4 turns | Taproom + light distro |
| 10–15 | 3–6 turns | Multi-brand, seasonal, flagships |
| 20–30 | 4–8 turns | Packaging line alignment, wholesale growth |
Right-sizing lowers COGS. Undersized systems force double-shift days; oversized systems hurt cash flow. Align brewhouse to cellar (fermenteur/unitank) volume and packaging cadence.

Cellar choices: fermenters, unitanks, fittings, and control
In the cellar, acier inoxydable conicals provide headspace and geometry for quick yeast drop. A fermenteur conique with 60–70° cone helps harvest, dump trub, and clarify efficiently. For flexibility, a unitank (pressure-rated) lets you ferment, crash, and carb in one réservoir, trimming transfers and oxygen risk.
Pay attention to ports and fittings. 1.5″ tool-less tri-clamp ferrules speed hop doses, sampling, and purges. Dedicated spools for dry hop, spunding, and an in-line oxygenation kit enhance dissolved O₂ control before pitch. Add jackets and contrôle de la température loops so the fermenteur holds setpoints through vigorous fermentation.
Heating options: steam, direct-fire, or electric?
Steam shines for step-mashing and tight ramp control. Direct-fire can be cost-effective at small sizes, but require careful combustion design. Brassage électrique is clean and quiet, ideal for urban spaces with power capacity and emissions rules. Whatever you choose, size the burner or elements to reach boil in a reasonable window while keeping caramelization in check.
Good build quality reduces long-term costs: thicker shells, clean welds, and polished stainless interior surfaces improve durability and cleaning. Insulation lowers energy use and protects staff.
Utilities & layout: hot liquor, heat exchanger, wort chiller, pump, and grain handling
Utilities make or break your day. A hot liquor tank (HLT) stabilizes strike/sparge temps and slashes heat-up time between turns. A two-stage échangeur de chaleur (city water + glycol) drops moût to pitch temp quickly, while a dedicated pompe à moût preserves gentle laminar transfer.
Upstream, a malt scale and Moulin à grain with consistent crush feed the mash. Use grist hydrators and under-let to avoid dough balls, then sparge evenly to keep run-off clear. Specify ergonomic platforms and hose drops so crews move safely between cuves d'empâtage and vessels without kinks or trip points.
CIP & sanitation: clean fast, avoid contamination
Fast, reliable cleaning is non-negotiable. A dedicated CIP cart, spray balls, and reclaim loops shorten turn-around while saving water and chemicals. Proper sanitation requires time, temperature, and turbulence—verify all three. Keep a tight gasket program, and rotate cleaning equipment so every line sees detergent and sanitizer at spec.
Design to prevent contamination: purge lines with CO₂ before cold-side transfers, minimize dead legs, and keep sight glasses shaded. Validate with ATP swabs and regular plate counts—small checks prevent big losses.
Fermentation control: yeast health and quality you can taste
Healthy levure is your best insurance policy. Oxygen appropriately with your in-line oxygenation kit, pitch by cell count, and control exotherm with balanced jackets. Harvest at peak vitality, store cold, and repitch with measured generations. Doing so helps you brew exceptional beer with bright aromatics and repeatable attenuation.
QA starts early: record pH in purée, gravity in the kettle/lauter run-off, and DO on transfers. Cold-crash, fine, or filter as your style demands—and log everything. When the team sees trends, they fix problems before customers taste them.

Packaging & service: brite tank, keg, and beyond
A réservoir de brite gives you a stable, carbonated buffer before package. It also polishes haze for lagers and clean ales. Serving “brite” from a dedicated line reduces drift and keeps draft flavor consistent. For small formats, tonneau workflows should include cold holds, CO₂ breakout checks, and meticulous headspace control.
If you package, match your réservoir de brite volume to filler speed and day targets. A canning day that chases the cellar is stressful; a brite buffer makes the line hum and your crew breathe easier.
Cost & ROI: where the time and money go
Where does your day go? Use this rough split to spot efficiency wins.
Time on a typical turn
- Hot-side (heat-up, purée, run-off, boil, knock-out): ~45–55%
- Cellar (transfer, dry hop, crash): ~25–35%
- Cleaning/Cycle-backs (CIP, hoses, floors): ~15–20%
Simple ROI snapshot
| Lever | Typical Gain | Example Impact |
|---|---|---|
| Faster knock-out (bigger échangeur de chaleur) | 20–30 min saved/turn | +1 extra turn per week |
| Better lauter geometry | 10–15% shorter run-off | Less labor OT |
| Dedicated CIP cart | 25–40% shorter clean | More tank turns/month |
| Smarter glycol zoning | 8–12% energy cut | Utility spend ↓ |
For a microbrasserie adding a second shift, shaving 45 minutes per turn across 5 turns/week returns >30 hours/month—enough to absorb new distro orders without hiring immediately.

FAQ
What size brewhouse should I start with?
Start where demand and cash flow meet. Many launch at 7–10 bbl with cellar sized for 2–3 turns/day, then add vessels as SKUs and tap handles grow.
Do I need steam or can I go electric?
Both work. Brassage électrique is clean and quiet, great for urban spaces. Steam offers fast ramps and multi-vessel control—ideal for step purée programs.
What’s the difference between a fermenter and a unitank?
A fermenteur is for primary fermentation; a unitank is pressure-rated so you can carb and package from the same réservoir. Unitanks reduce transfers and O₂ risk.
How do I minimize oxygen when transferring?
Purge lines and vessels, use CO₂ blankets, and keep a gentle pompe à moût curve. If possible, package from a réservoir de brite with DO checks at filler.
How should I plan for packaging?
Match brite volume to line speed and sales cadence. If you’re draft-heavy, invest in tonneau cleaning and cold storage first.
Is a whirlpool essential?
Yes for most setups. It speeds trub separation and hop stand control, improving clarity and flavor consistency.
