Grade 304 stainless steel (AISI 304) forms the baseline for vessel interiors. For contact surfaces exposed to high-chloride cleaning agents or coastal environments, 316L provides added pitting resistance. Wall thickness specifications vary by vessel function: brewhouse kettles typically use 4mm\u20135mm inner shells to withstand boiling temperatures and thermal stress, while fermentation tanks employ 3mm\u20134mm shells with 50mm\u201380mm of polyurethane foam insulation.<\/p>\n\n\n\n
Welding integrity remains the single most reliable indicator of vessel longevity. Full-penetration TIG welds, back-purged with argon, produce smooth, crevice-free seams that resist bacterial harbourage. Internal surface finishes at 0.4\u20130.6\u03bcm Ra are the industry benchmark\u2014rough enough to retain passivation, smooth enough to clean effectively.<\/p>\n\n\n\n
Brewhouse Configuration<\/strong> For breweries producing both ales and lagers, a dedicated hot liquor tank with variable temperature control is non-negotiable. Mash mixing systems\u2014either raking or paddle-driven\u2014must offer variable speed to handle different grist-to-water ratios without compacting the grain bed.<\/p>\n\n\n\n The cellar, not the brewhouse, ultimately determines beer quality and production throughput. Fermentation tanks in the 1000L\u20133000L range are universally specified as unitanks\u2014dual-purpose vessels that perform both primary fermentation and maturation under pressure.<\/p>\n\n\n\n Jacket Configuration<\/strong> Pressure Ratings and Safety<\/strong> Conical Geometry<\/strong> Purchasing decisions at this scale often fail because buyers overestimate production capacity or underestimate cycle times.

This is not a side business or a product line extension; it is our core engineering discipline.<\/p>\n\n\n\n Engineering Depth<\/strong> Regional Compliance Expertise<\/strong> Integrated Turnkey Brewery Solutions<\/strong> After-Sales Commitment<\/strong> Reference Installations<\/strong> The decision to scale into the commercial craft beer equipment tier is a substantial capital commitment\u2014one that shapes production capabilities, brand positioning, and operational costs for a decade or more. The difference between a profitable regional brewery and one burdened by inefficiency often traces back to equipment specification, supplier integrity, and the integration of systems like CIP, automation, and cellar design.<\/p>\n\n\n\n A turnkey brewery solution simplifies this complexity by aligning every component to a coherent production plan. Fermentation tanks sized for actual output, a CIP cleaning system engineered for effective sanitation, and PLC automation control that delivers repeatable results collectively determine whether a brewhouse operates at 70% or 95% of theoretical capacity.<\/p>\n\n\n\n
Buyers choose between 3-vessel and 4-vessel configurations. A\u00a03-vessel\u00a0system combines mash\/lauter in one unit with separate kettle and whirlpool, or uses a mash tun, lauter tun, and combined kettle\/whirlpool. It saves floor space and capital while supporting two to three turns per day. A\u00a04-vessel\u00a0system dedicates separate vessels to mashing, lautering, boiling, and whirlpooling\u2014enabling three or more daily turns, better wort clarity, and independent stage control. Efficiency gains typically offset the higher cost within 18\u201324 months for high-output or multi-style breweries.<\/p>\n\n\n\nFermentation Tanks and Cellar Design<\/h3>\n\n\n\n
Effective temperature control requires adequate jacket surface area. Dimple plate jackets provide 30\u201340% coverage on conical and cylindrical sections, sufficient for standard ales. For lagers requiring precise 8\u201310\u00b0C fermentation profiles, a combination of cone and sidewall jackets ensures even cooling without stratification. Glycol flow rates typically range from 2\u20133 m\u00b3 per hour per 1000L vessel, matched to a chiller plant sized for peak load.<\/p>\n\n\n\n
Commercial fermentation tanks are designed for 1.5 to 2.5 bar working pressure. This allows natural carbonation during closed fermentation and pressure transfers without pumps\u2014a technique widely adopted by EU brewers to reduce oxidative pickup. Safety relief valves, burst discs, and pressure gauge redundancy are standard fitments. Australian regulations impose additional certification requirements (AS 1210), which a qualified brewery equipment manufacturer should supply as part of the documentation package.<\/p>\n\n\n\n
A 60\u00b0 to 70\u00b0 cone angle optimises yeast harvesting and trub settling. Steeper angles reduce the yeast cake surface area, minimising autolysis risk during extended maturation. For breweries planning to repitch yeast for multiple generations, cone manways and sight glasses at the harvest port are practical additions.<\/p>\n\n\n\n![\"2000](\"https:\/\/metobrew.com\/wp-content\/uploads\/2026\/05\/2000l-brewery-2.webp\")
<\/figure>\n\n\n\nBuying Guide: Matching Capacity to Production Goals<\/h3>\n\n\n\n
A 1000L brewhouse does not deliver 1000L of finished beer per batch. Wort losses occur at multiple points: evaporation during boiling (4\u20138%), trub retention in the whirlpool (3\u20135%), yeast and hop absorption in fermentation (2\u20134%), and filtration losses (1\u20133%). A realistic brewhouse yield is 85\u201390% of nominal volume. A 3000L system therefore produces approximately 2550\u20132700L of clear, packaged beer per batch.<\/p>\n\n\n\n
A single brewhouse batch fills one fermentation tank of equivalent size. If a brewery runs one batch per day and the fermentation cycle averages 14 days, the minimum tank fleet is 14 vessels plus one spare\u201415 tanks total. This does not include bright beer tanks for conditioning and carbonation. Many breweries maintain a 1.5:1 ratio of fermentation to bright tank capacity to absorb schedule variability.<\/p>\n\n\n\n
The supporting utilities often cost as much as the vessels themselves. Key considerations:<\/p>\n\n\n\n\n
A 3000L fermentation tank with insulation stands approximately 4.5\u20135.0 metres tall. Adding a manway access platform and overhead pipework requires a clear ceiling height of 6.0 metres minimum. These constraints often drive facility selection before equipment ordering.<\/p>\n\n\n\nProcurement and Supplier Evaluation<\/h3>\n\n\n\n
EU-bound equipment must carry CE marking covering the Pressure Equipment Directive (PED 2014\/68\/EU). US installations require ASME U-stamp certification for pressure vessels over certain thresholds. Australian projects need compliance with AS 1210 and state-based boiler inspection regimes. A brewery equipment manufacturer that proactively provides these certifications, rather than charging extra for them, demonstrates engineering maturity.<\/p>\n\n\n\n
1000L\u20133000L vessels are oversize cargo. Shipping costs\u2014and more critically, delivery timelines\u2014vary wildly based on port proximity and containerisation. Flat-rack or open-top containers suit vessels up to 2.5 metres diameter. Larger tanks require break-bulk shipping, which extends lead times by 4\u20136 weeks. Ask for a logistics plan with assigned freight forwarder and marine insurance.<\/p>\n\n\n\n
On-site installation supervision is not a luxury; it is a risk-mitigation measure. A properly commissioned brewhouse operates at the quoted efficiency from day one. Poorly commissioned equipment suffers from false readings, thermal inefficiencies, and control logic errors that cost months of troubleshooting. Training should cover not only operations but also maintenance schedules for pumps, valves, and the CIP cleaning system.<\/p>\n\n\n\n
The useful life of commercial craft beer equipment spans 15\u201320 years. Suppliers that maintain a stocked spare parts warehouse and offer remote diagnostic support reduce downtime significantly. Enquire about response times for critical failures\u2014a control board or solenoid valve should ship within 24 hours for premium suppliers.<\/p>\n\n\n\nFrequently Asked Questions<\/h3>\n\n\n\n
Lead times range from 12 to 20 weeks for standard configurations, depending on factory workload and vessel complexity. Custom fabrication\u2014non-standard manway positions, special jacket patterns, or bespoke control interfaces\u2014adds 4\u20138 weeks. Include shipping and customs clearance when calculating total project duration.<\/p>\n\n\n\n
Not practically. Brewhouse vessels are dimensioned for specific thermal and hydraulic loads. Increasing capacity requires larger kettles, different heat exchanger sizing, and upgraded utilities. Plan for the final capacity at the outset; modular add-on fermentation tanks, however, can scale cellar capacity without replacing the brewhouse.<\/p>\n\n\n\n
Assuming a 14-day fermentation cycle and one brew per day, you require 14 fermentation tanks for continuous operation. Add one spare tank for maintenance coverage. Add bright beer tanks equal to 50\u201370% of fermentation capacity, depending on packaging turnover.<\/p>\n\n\n\n
Yes. Manual cleaning of 3000L tanks is impractical, unsafe, and inconsistent. A CIP cart with caustic, acid, and sanitiser dosing pumps automates the cleaning cycle. Fixed CIP systems with spray balls on each tank offer higher reliability and lower chemical usage over time.<\/p>\n\n\n\n
Well-designed brewhouses achieve 92\u201395% mash efficiency and 85\u201390% overall brewhouse yield. Factors affecting this include grist milling quality, lauter rake design, sparge water distribution, and boil-off rate. A new system should be commissioned with a benchmark brew to validate performance.<\/p>\n\n\n\n
Critical. Poor insulation causes temperature drift during active fermentation, leading to off-flavours from stressed yeast. 50\u201380mm polyurethane foam with an external stainless cladding maintains \u00b10.5\u00b0C control. In hot climates (Australian summers, Texas heat), thicker insulation or additional jacketing pays back through reduced chiller runtimes.<\/p>\n\n\n\n
Request PID drawings, general arrangement drawings, electrical schematics, pressure vessel calculation reports, material test certificates, and a detailed utility consumption table. A professional supplier provides these before payment, not after.<\/p>\n\n\n\n
Yes. Fermentation tanks with glycol cooling handle both temperature ranges (18\u201322\u00b0C for ales, 8\u201312\u00b0C for lagers). The difference lies in the chiller sizing\u2014lagers require greater cooling capacity. Discuss your intended beer portfolio with the supplier to ensure the glycol plant is sized appropriately.<\/p>\n\n\n\nWhy Choose METO<\/h3>\n\n\n\n
