What Questions Should You Ask Before Buying Turn-Key brewery solutions?
Before buying a turn-key brewery, ask the supplier to prove production capacity, not just tank size. A 20 hL brewhouse producing 4 batches per day has very different utility, cellar, and labor requirements from the same brewhouse producing 1 batch. Confirm usable tank volume, brewhouse cycle time, fermentation capacity, glycol demand, steam demand, water use, electrical load, CIP coverage, automation level, pressure ratings, installation scope, and acceptance tests. Require every promised performance figure in writing. Also compare spare-parts availability, expansion capacity, warranty terms, commissioning work, and total installed cost rather than relying on the equipment quotation alone.
A brewery purchase should start with the production calendar. If the plan calls for 20 hL per brew, 3 brews per day, 5 brewing days per week, theoretical wort production reaches 300 hL per week before losses, fermentation time, cleaning, or packaging are considered. A supplier should show how mash, lautering, boiling, whirlpool, transfer, and CIP times fit inside that schedule.
Tank sizing follows from the same calculation. Twelve 40 hL fermenters provide 480 hL of nominal volume, but nominal volume is not the same as usable beer volume because headspace is required for fermentation. A buyer should ask for gross volume, working volume, cone volume, maximum filling level, design pressure, and the assumed fermentation cycle for every vessel.
Ask the supplier to model at least 3 representative beers: a fast ale, a longer-conditioned lager, and the highest-gravity product planned for the brewery. A cellar sized only around a 14-day ale cycle can become undersized when part of production occupies tanks for 21–35 days.
Once capacity is clear, review what “turn-key” actually includes. One quotation may cover the brewhouse, cellar, glycol chiller, steam generator, CIP station, controls, platforms, process piping, installation, and commissioning; another may stop at equipment delivery. A price difference of 15% can disappear quickly when local piping, electrical work, insulation, lifting equipment, drainage, and commissioning are added later.
The scope sheet should therefore identify every major item by quantity, capacity, material, manufacturer, and responsibility. Buyers comparing Beer Brewing Equipment should also request a written exclusion list covering boilers, chillers, air compressors, water treatment, laboratory equipment, packaging connections, freight, customs charges, site labor, and operator training.
Material specifications deserve the same level of detail. “Stainless steel tank” is not enough. Ask whether product-contact surfaces are 304, 316, or 316L stainless steel, what thickness is used in the shell and heads, how welds are finished, whether internal surfaces are passivated, and which sanitary fitting standard is supplied.
For many brewery tanks, a polished internal surface around Ra 0.8 μm or better may be specified, but the number should match the process and contract rather than appear only in sales literature. Ask how surface roughness is measured, how many locations are checked, and whether inspection records are supplied before shipment.
Pressure ratings need equally clear documentation. A fermenter operating near 1–2 bar needs suitable vessel construction, relief protection, pressure gauges, fittings, and fabrication procedures. In the United States, pressure-vessel requirements may involve ASME BPVC rules depending on vessel design and local jurisdiction; buyers should confirm the applicable 2025 or later code edition with the engineer or authority responsible for the installation.
| Item to verify | Supplier should provide |
|---|---|
| Fermenter | Gross volume, working volume, design pressure, test method |
| Brewhouse | Batch size, cycle time, brews per 24 hours |
| Chiller | Cooling capacity at stated glycol temperature |
| Boiler/heater | Steam or electrical demand at peak production |
| CIP | Tank volume, pump flow, pressure, heating method |
| Controls | PLC/HMI brand, I/O capacity, software access |
| Documentation | P&ID, electrical drawings, manuals, spare-parts list |
Utility sizing should be checked against the busiest operating hour rather than a daily average. During a production day, wort may be boiling while another vessel is being heated, a fermenter is being cooled, and CIP water is being prepared. Ask for peak kW, steam kg/h, glycol kW, compressed-air flow, water flow, and wastewater discharge under that operating case.
Water deserves extra attention because brewing uses much more water than the liquid contained in the package. Beer itself is roughly 90–95% water, while total facility use also includes vessel cleaning, floor wash, bottle or keg cleaning, cooling, and utility make-up. A supplier should state where water can be recovered and where it must go to drain.
For example, wort cooling can transfer a large share of wort heat into incoming brewing water. If 2,000 L of wort is cooled from near boiling temperature to fermentation temperature, the recovered hot water can be stored for the next mash or cleaning cycle. Ask whether the hot-liquor tank is large enough to receive that water without overflowing during consecutive brews.
Cleaning capacity should then be examined together with the piping arrangement. A 2- or 3-tank CIP station may use separate vessels for caustic solution, acid or sanitizer, and recovery water. The supplier should state CIP pump flow, pressure, return method, solution temperature, heating time, spray-device requirements, and which tanks can be cleaned without manual hose connections.
Poor piping geometry can reduce the benefit of a good CIP skid. Ask for a P&ID showing product routes, CIP supply, CIP return, drain points, sample points, valves, pumps, and instruments. Horizontal lines should be arranged for drainage, and branches should be reviewed so cleaning solution reaches the full wetted surface.
Request the P&ID before fabrication reaches the point where pipe routing is difficult to change. Reviewing 1 drawing before production can cost very little; modifying 20 welded lines after installation can require new fittings, labor, insulation, and another commissioning visit.
Automation should be specified function by function. “Automatic brewhouse” can describe anything from temperature control with motorized valves to a recipe system controlling water dosing, mash steps, pump speeds, transfers, heating, alarms, and batch records. Ask the supplier to list every automatic sequence and every step that still needs an operator.
Component selection affects serviceability for the next 10–15 years. Request the PLC, HMI, VFD, temperature sensor, pressure transmitter, flowmeter, solenoid, and control-valve manufacturers. Ask whether local distributors stock replacements and whether your brewery receives backups of PLC and HMI programs after commissioning.
Spare control capacity is worth discussing before the panel is built. If the first installation has 12 fermenters but the site may grow to 20, ask whether the panel has enough I/O, power capacity, network capacity, and software structure for 8 additional tanks. Adding capacity during fabrication is usually simpler than replacing a full control panel during production.
Cooling deserves a separate calculation because fermentation and crash cooling do not place the same demand on the glycol system. Ask the supplier to calculate the load created when several fermenters are active while another tank is being cooled from fermentation temperature toward 0–2°C. A chiller selected only from average cellar temperature can struggle during overlapping cooling events.
The same approach applies to heating. A supplier should state how long it takes to raise a defined water or wort volume through a defined temperature range. Comparing a “100 kW heater” with another system is less useful than comparing the time required to heat 2,000 L under the stated operating conditions.
Production flexibility should also be tested against actual recipes. Ask about maximum grain weight per mash, minimum and maximum liquor-to-grist ratio, lauter bed depth, pump flow control, hop addition method, whirlpool geometry, and practical kettle working volume. A recipe using 20–30% more malt than a standard-strength beer may require more mash and lauter capacity even when final batch volume stays unchanged.
Dry-hopped beer creates different questions. If a tank receives large hop additions, ask how hops enter the vessel, how oxygen exposure is controlled, how blocked outlets are handled, and how much working headspace is available. A tank that performs well with a lightly hopped lager may require different fittings for a heavily dry-hopped ale.
Packaging should enter the discussion before the cellar layout is fixed. A canning line processing 2,000 cans per hour and one processing 12,000 cans per hour place very different demands on bright-beer availability, carbonation, transfer flow, compressed air, CO₂ supply, staffing, and cold storage. The brewery supplier should confirm that transfer pumps and piping can supply the planned packaging rate.
Expansion planning should use numbers rather than a general promise that more tanks can be added later. Ask how many extra fermenters the glycol system can cool, what percentage of chiller capacity remains unused, whether the steam system can support another daily brew, and whether pipe headers have connections sized for the planned second phase.
Documentation should arrive before the equipment. At minimum, request general arrangement drawings, tank drawings, utility schedules, electrical schematics, P&IDs, equipment manuals, recommended spare-parts lists, and foundation or floor-loading information. For a project containing 30–50 powered devices, a complete electrical schedule can prevent substantial field rewiring.
Factory acceptance testing should be agreed before the purchase order is released. The inspection can cover dimensions, weld appearance, pressure or leak tests, motor rotation, valve operation, control-panel functions, sensors, pumps, safety devices, and documentation. For a large system, buyers may divide FAT into mechanical, electrical, and control checks instead of relying on a short visual inspection.
Site acceptance should then verify installed performance. Test heating time, cooling time, transfer rate, temperature control, alarms, CIP circulation, pressure protection, and communication between the PLC and field devices. A contract stating “brewhouse capacity 20 hL” is weaker than one stating the agreed volume, measurement point, operating conditions, and test procedure.
Tie the final payment milestone to documented acceptance work. A structure such as 30% deposit, 60% before shipment, and 10% after agreed commissioning checks gives the buyer and supplier a defined completion point; percentages should be negotiated around project size and commercial terms.
After-sales support should be quantified as carefully as production capacity. Ask when the warranty starts, whether it covers parts only or parts plus labor, who pays international freight, what remote-support hours are available, and what happens if a PLC, pump seal, temperature probe, or valve actuator fails during production.
A spare-parts package should reflect equipment that can stop brewing. Even if spare parts equal only 1–3% of equipment purchase cost, stocking seals, sensors, contactors, relays, valve kits, pump seals, and selected control components can reduce dependence on emergency shipments. The exact list should come from the final bill of materials.
Finally, compare total installed cost on the same basis. Equipment price may exclude freight, duties, rigging, foundations, drainage, ventilation, electrical distribution, steam piping, glycol piping, insulation, water treatment, laboratory equipment, commissioning, and local permits. A quotation that appears 10% cheaper can cost more after those items are added.
Before paying the deposit, require one controlled specification package containing capacities, materials, utility requirements, approved drawings, automation scope, installation responsibilities, acceptance tests, training, warranty terms, spare parts, and expansion allowances. If a promised figure cannot be connected to a drawing, calculation, datasheet, test, or written acceptance requirement, ask the supplier to document it before fabrication begins.
