Starting a microbrewery is one of the most exciting and challenging things you can do in the craft beverage world. You've probably been dreaming about this for years—maybe you're homebrewing and ready to go pro, or maybe you're a beer lover who wants to turn passion into a business. Either way, you're going to need equipment, and figuring out what to buy can feel overwhelming.
We're here to help cut through that confusion. We've helped hundreds of breweries get started, and we've seen what works (and what doesn't) across a wide range of setups and scales. Let's walk through everything you need to think about when planning your microbrewery equipment.
First, let's clarify the terminology. BBL stands for "barrel," and in the US brewing industry, one barrel equals 31 gallons. So:
A 3BBL system produces about 93 gallons per batch
A 5BBL system produces about 155 gallons per batch
A 10BBL system produces about 310 gallons per batch
For context, a standard half-barrel keg holds 15.5 gallons, so:
3BBL = roughly 6 kegs per batch
5BBL = roughly 10 kegs per batch
10BBL = roughly 20 kegs per batch
The system size you choose determines your batch size, so think carefully about your production goals.
3BBL systems are popular for several reasons:
Lower initial investment
Easier to manage for a small team
Great for taproom-focused operations
Lower operating costs (less ingredients, utilities, waste)
Perfect for specialty and small-batch brewing
If you're primarily selling draft beer from your own taproom, a 3BBL system can be ideal. You can brew more frequently, experiment with different styles, and keep your offerings fresh and varied.
5BBL systems offer a nice middle ground. You get more production capacity while still maintaining some of the flexibility of smaller batches. Many breweries start here and stay.
10BBL systems make sense when:
You want to distribute to multiple accounts
You're planning for significant taproom volume
You have ambitions for faster growth
You're in a high-traffic location with strong demand
Here's our honest advice: be realistic about your projections. We've seen too many breweries struggle because they overbought equipment and can't fill it consistently. Start smaller if you're uncertain—you can always scale up.
Your brewhouse is where the magic begins. For most microbreweries, you're looking at either a 2-vessel or 3-vessel system:
2-Vessel Systems (Mash/Lauter Tun combined with Boil Kettle)
Lower upfront cost
Requires more time between batches
Takes up less space
Good for straightforward beer styles
3-Vessel Systems (Separate Mash Tun, Lauter Tun, and Kettle)
Faster batch turnaround
More flexibility for complex brewing
Better efficiency
Higher initial investment
For most starting microbreweries, a well-designed 2-vessel system works great. As you grow and find yourself rushing between batches, you can always add capacity.
You'll need fermenters to hold your beer while yeast does its work. Here's what to consider:
Sizing Your Fermenters
As a rule of thumb, we recommend having enough fermenter capacity to hold 1-2 weeks of production. So if you're brewing 5-barrel batches twice a week, plan for at least 4-6 fermenters.
Must-Have Features
Stainless steel construction (304 grade minimum)
Cooling jackets for temperature control
Pressure-rated for flexibility
Sample ports for quality checking
Bottom dump valves for easy cleaning and yeast harvesting
Bright tanks (also called conditioning tanks or serving tanks) are where your beer gets carbonated and ready for serving. Unlike fermenters, these don't need cooling jackets—you're just holding finished, carbonated beer.
Plan for 1-2 bright tanks per fermenter for maximum flexibility. This lets you have beer conditioning while fermentation continues.
Hot Liquor Tank (HLT)
Used to heat and hold brewing water. Essential for your next batch's strike water.
Cold Liquor Tank (CLT)
Holds cold water for cooling between batches and recipe adjustments.
Glycol Chiller
Your fermentation temperature control depends on this. Don't underestimate sizing—under-powered chillers lead to warm fermentation and off-flavors.
Water Treatment Equipment
Municipal water almost always needs treatment for optimal brewing. At minimum, you need filtration and often pH adjustment.
Cleaning Equipment
CIP (Clean-In-Place) systems, sanitizers, and appropriate brushes and tools.
Kegs
Plan for 2-3 times your weekly production in keg inventory. You'll always be washing and rotating.
Here's a realistic cost range for a complete 3BBL system:
Brewhouse (2-3 vessel): $30,000-$80,000
Fermenters (4-6 units): $25,000-$50,000
Bright tanks (3-4 units): $15,000-$30,000
Supporting tanks (HLT, CLT): $5,000-$15,000
Glycol chiller: $8,000-$20,000
Installation and plumbing: $10,000-$30,000
Electrical work: $5,000-$15,000
Water treatment: $2,000-$8,000
Kegs (30-50): $15,000-$35,000
Miscellaneous: $5,000-$10,000
A complete 3BBL system realistically runs $120,000-$300,000 depending on quality and new vs. used equipment.
For a 10BBL system, multiply most of these costs by 2-3x.
Permits and licensing: TTB approval, state licenses, local permits—budget several thousand and many months of waiting.
Location buildout: If you're not moving into a turnkey space, TI (tenant improvement) costs can be enormous. Electrical capacity, plumbing, ventilation, floor drains—these add up fast.
Operating capital: You won't be profitable immediately. Budget for 6-12 months of operating expenses while you build distribution and taproom traffic.
Professional services: Brewery design consultation, brewing software, accounting, legal—these professional services matter.
For a functional 3BBL brewery with basic packaging, we recommend at least 1,500-2,500 square feet. This includes:
Brewhouse and brewing area
Fermentation cellaring
Taproom/bar seating
Cold storage
Keg storage
Basic office space
Bathroom
A 10BBL operation typically needs 3,000-5,000+ square feet depending on packaging and taproom plans.
Think about your brewing flow from start to finish:
Receiving and storage (malt, hops, yeast)
Milling
Brewing (mashing, lautering, boiling)
Fermentation cellaring
Conditioning and carbonation
Packaging (kegging, bottling, canning)
Finished goods storage
Taproom/customer area
Minimize backtracking and ensure adequate space for each stage.
Let me walk you through how we help breweries think through this. We ask them to answer a few key questions:
What's your target weekly production?
What's your taproom vs. distribution split?
How many styles do you want to brew simultaneously?
What's your timeline and budget?
Do you have expansion plans?
From there, we can spec out a complete system that actually makes sense for their situation.
For example, a 5BBL taproom brewery targeting 200 barrels per month might get:
1x 5BBL brewhouse (2 or 3 vessel)
8x 5BBL fermenters
4x 5BBL bright tanks
Appropriate HLT, CLT, and chiller
Supporting equipment
Here's what we've learned from watching hundreds of breweries launch:
Start with quality you can afford. Cheap equipment will cost you more in the long run through inefficiency, maintenance headaches, and quality problems.
Don't buy everything at once. Some equipment (like bottling lines) can wait until you actually need it.
Plan for growth, but not excessive growth. Buy for where you'll be in 2-3 years, not where you hope to be in 10.
Work with experienced suppliers. We've seen too many new breweries get sold equipment that doesn't work for their situation.
