15 BBL brewing equipment
Overview of 15 BBL brewing equipment
A 15 BBL brewing equipment allows medium-large craft breweries to scale up annual production between 5000 to 10,000 barrels while retaining flexibility for specialty small batches.
With a brewhouse batch capacity of 31 gallons x 15 = 465 gallons or 1554 liters per brew, 15 BBL configurations suit taproom brewpubs graduating beyond 10 BBL as well as smaller regional production facilities.
These automated stainless steel brewhouses represent a sizable investment between $900,000 to $1.8 million installed but deliver higher output volume and efficiencies. Their strategic batch size bridges production gaps between mid-sized 10 BBL and larger 30 BBL mega-breweries.
This guide provides a detailed analysis of 15 BBL professional brewing technology – covering equipment configurations, sizing calculations, layouts, customization options, pricing, supplier selection criteria, operations best practices, pros and cons, and expert recommendations.
Types of 15 BBL brewing equipment
15 BBL brewhouses are available in 4-vessel and 3-vessel configurations from leading brewery equipment manufacturers:
4-Vessel Brewhouses
With separate hot liquor tank, mash tun, lauter tun and brew kettle vessels connected via transfer pipes and pumps.
Advantages: Traditional process, flexibility for complex recipes
Disadvantages: Larger footprint, more manual operations
3-Vessel Brewhouses
Combine mashing and lautering functions into one vessel. More compact layout.
Advantages: Lower cost, smaller footprint
Disadvantages: Restrictions on specialty ingredients
| Type | Number of Vessels | Automation Level |
|---|---|---|
| 4-Vessel | Hot Liquor Tank + Mash Tun + Lauter Tun + Kettle | Medium |
| 3-Vessel | Mash/Lauter Tun + Kettle (+ Whirlpool) | High |
Within these configurations, additional options include multi-stage mash filters, internal/external calandria boiling systems, whirlpool settlers, yeast propagators, steam generators etc. – all customizable to balance functionality, degree of automation and budget.
15 BBL brewing equipment Batch Size and Capacity
The “15 barrel” denomination refers to a single completed batch volume capacity. One beer barrel = 31 US gallons.
So 15 barrel systems allow brewing 15 x 31 = 465 gallons per full brewing cycle from mashing to boiling, cooling and fermentation.
In practical annual production terms:
- Max brews per week: 4 to 5
- Annual beer output at 80% utilization: 7500 to 10,000 barrels
- Actual yield per 15 BBL batch after losses: 400 gallons, or 1500 liters
- Sellable case equivalent per batch at 355ml/bottle: 570 cases
- Fermentation tank capacity needed: Up to 30 BBL, or 4x batch size
For a taproom restaurant pairing, this matches daily draft consumption of 300 liters while allowing distribution growth. Larger brewpubs may consider dual 15 BBL systems for peak demand. For production breweries targeting 20,000 barrels yearly, installing multiple units allows staggered brewing cycles.
15 BBL brewing equipment Design and Layout Considerations
Constructing or upgrading facilities for 15 BBL professional brewing equipment involves many infrastructure factors:
Height: 30 ft floor to ceiling for overhead clearance of tanks, pipes, mezzanines, cranes
Flooring: Reinforced concrete floor graded for drainage, HACCP compliant
Power: 480V, 3-phase electrical supply with 400 amp+ capacity for heating elements
Water: 1.5 inch diameter supply lines for high flow hydraulic demands
Steam: Clean steam generator and piping for heating mash tuns
Cooling: Glycol chilling with supply and return manifold connections
Ventilation: Humidity, fume and odor control systems
Safety: Chemical storage compliance, emergency eyewash stations
Ancillary: Adjacent cold storage, water treatment, boiler and compressor rooms
Expansion: Floor space for doubling batch capacity over 5 year growth
In terms of optimal brewhouse layout design:
- Grain handling and raw material receiving bay near mash tun inlet
- Ergonomic work triangles allowing single operator movement between vessels
- Gravity flows utilized before pump transfers where possible
- Services access underneath vessels without confined spaces
- Utilities, electrical, drains planned for maintenance access
- Quality lab and control room visibility across equipment
- Open architecture allows modular expansion
- Restaurant/tasting room aesthetic views of brewery
There are significant construction planning interdependencies between brewhouse capabilities, building engineering constraints, production growth plans and budget. Experienced brewery design consultants manage these complex tradeoffs from end-to-end.
