By planning thoroughly and investing wisely in commercial beer brewing equipment, an excellent beer can be brewed from the first batch to the millionth. Let’s get brewing!


What size brewhouse system should I get for a new brewery?
Base your brewhouse size on annual barrelage targets. Allow room to grow – downsizing is extremely difficult! For a new brewpub, a 3-5 barrel system may work. For a packaging microbrewery, 7-15 barrels is typical. Regional breweries often start with a 30-60 barrel system. Time your expansions as demand grows.

How much fermentation capacity do I need for commercial brewing?
Plan fermentation tank capacity to match peak brewhouse output. Aim for 2-3 turns per week as a goal. For example, a 10 barrel brewhouse would need 20-30 barrels of fermentation space at minimum for efficient operation. Allow space in the room to add more tanks later.

What types of fermentation and lager tanks work best?
Cylindroconical stainless steel fermenters are preferred in commercial brewing. They have conical bottoms to collect yeast and siphon off trub. Dual cooling wall jackets for precise temperature control. Sizes match brewhouse volumes. Open fermenters see limited use for ales.

How do I choose the right boiler and hot water system?
Consult with your brewery engineer on boiler sizing for steam generation or direct heat under the brewkettle. Ensure capacity for future expansion. Provide adequate heated water for cleaning and brewing use – high pressure, 185°F minimum. Insulate piping to conserve heat.

What are the pros and cons of different brewkettle designs?
Steam heated kettles are slower to respond but very consistent. Direct fire kettles heat quickly but need experienced operators. Internal calandria heating has advantages but requires separate steam source. Whirlpools can be integrated or standalone. Evaluate options carefully for your goals.

How many beer serving tanks should be installed?
Aim to have at least 1-2 weeks of finished beer storage capacity on site to allow for packaging scheduling flexibility. More lagering time may be needed for specialty beers. Serving tanks allow smoothing out production flow.

What types of beer packaging equipment should I choose?
Base your packaging format (kegs, cans, bottles) on targeted customers and sales channels. Kegs and cans dominate for most craft breweries starting out due to cost. Consult a packaging specialist to properly spec out a packaging line for your needs. Expect future upgrades.

How much lab equipment is required on site?
At minimum, have wort and beer measurement instrumentation like hydrometers and refractometers. As production and varieties grow, invest in more advanced beer analysis tools – gravimetric, color, carbonation, microbiological. Labs allow better control of processes and final quality.

What utility capacity is needed to supply a 10 barrel brewhouse?
Plan on approximately: 45 kW electricity, 150,000 BTU/hr gas, 180-200 gallons/hr brewing liquor, 120 gal/hr cooling liquor minimum capacities. Size compressed air, wastewater, ventilation to suit all planned equipment. Leave room to expand – utilities are expensive to upgrade later.

Building an efficient commercial beer brewing operation takes careful equipment selection, design and training. But the high up-front investments pay back over the long run through more consistent quality, higher productivity and capacity to grow. Work with experienced consultants and vendors to avoid pitfalls. Allow room in the budget for upgrades and expansions down the road. With smart planning and execution, brewing beer on a grand commercial scale can be very rewarding both financially and creatively. Cheers to great beer!
