30 Barrel Brewhouses

30 bbl brewhouses are medium-sized professional beer production systems with an output capacity of 930 gallons or 3,510 liters per brewing batch. They are popular among expanding craft breweries looking to upgrade from pilot systems to higher volume commercial scale setups.

30 Bbl Brewhouse Equipment Guide

Main Components:

  • Mash tun – Stainless steel vessel where grist is steeped in hot water to extract sugars
  • Lauter tun – Separates sweet wort from spent grains
  • Brew kettle – Wort is boiled with hops here
  • Whirlpool – Settles out proteins, hops and coagulated particles
  • Heat exchanger – Cools hot wort to fermentation temperature
  • Fermenters/Brite tanks – Fermentation and carbonation

Auxiliary Equipment:

  • Grist case, mill, auger – Handles raw ingredients
  • Piping, pumps, valves, sensors – Fluid transfer
  • Control panel, software – Automated process operation
  • Grain handling system – Removes spent grain
  • CIP system – Interior cleaning


  • Filtering system – Enhanced wort clarity
  • CO2 recovery – Saves on gas usage
  • Steam generation – Internal heating unit

30 Bbl Brewhouse Design and Customization

Commercial 30 bbl brewhouses are mostly custom fabricated to match specific production goals, space constraints, and budgets.

Key design choices include:

  • Vertical vs. horizontal layout
  • Single vs. double brewing process
  • Direct vs. indirect heating
  • Level of automation
  • Made to order vs. modular construction
  • Material choice – stainless steel, copper, etc.
  • Type of fermentation – open vs. closed tanks
  • Serving tanks – brite vs. traditional
  • Additional functions like wort aeration, filtering, steam generation, etc.

Within a fixed footprint, prioritizing taller tanks yields higher capacity while shorter widths improve access. Tradeoffs are made between initial cost, production efficiency, consistency, labor requirements, maintenance needs and other factors.

  • Ventilation hoods over boil kettles
  • CO2 venting system with sensors
  • Lighting fixtures – LEDs avoid breakage

Daily Operation

  • Follow manufacturer instructions for each process stage
  • Track brew sheet calculations and measurements
  • Inspect functioning of valves, motors, sensors
  • Monitor flow rates, pressures and temperatures
  • Collect samples and record analytics
  • Perform problem diagnosis for unexpected readings
  • Coordinate grain handling, transfers, cleaning with teams
