Overview of 20 BBL Brewhouse

A 20 barrel (BBL) brewhouse is a medium-sized professional beer brewing system with a capacity to produce 20 barrels of beer per batch. This system is commonly used by microbreweries and brewpubs to efficiently produce craft beer on a commercial scale.

With a 20 BBL capacity, this brewhouse can output around 310-420 gallons per batch, or approximately 620-840 gallons per brew day. This allows an estimated annual production volume between 3,000-10,000 BBLs depending on the number of batches brewed per week. The flexibility of a 20 BBL brewhouse makes it suitable for expanding small breweries aiming to grow production and distribution.

20 BBL Brewhouse Equipment Guide

The 20 BBL brewhouse system consists of several key components for mashing, lautering, boiling, whirlpooling, cooling, and fermenting beer. Here is an overview of the equipment:

EquipmentDescription
Mash tunStainless steel vessel where the milled grains are mixed with hot water to convert starch into fermentable sugars. Common size is 20 BBL.
Lauter tunSeparates sweet wort from grains. Usually combined with the mash tun in a brew-in-a-bag system.
KettleBoils the wort with hops for flavor and preservation. Typically 20-30 BBL capacity.
WhirlpoolSEPARATOR to remove hops and coagulated proteins after boiling using a spinning motion.
Heat exchangerCools down hot wort quickly before fermentation. Plate or tubular style.
FermentersStainless steel, cone bottom tanks where yeast ferments the wort into beer. Multiple 20 BBL units.
Brite tanksPressurized vessels for carbonating, clarifying and storing finished beer. ≥20 BBL capacity.
PipingPlumbing connects all vessels for transferring liquids. Manual or automated.
Control panelControls temperatures and timing of key processes. Can be manual or computerized.

Types of 20 BBL Brewhouse Systems

20 BBL brewhouse systems are available in different configurations and price ranges to suit unique production goals:

TypeDescription
Traditional breweryHas separate mash tun and lauter tun for mashing and lautering. More manual operation but better efficiency.
Brewpub brewhouseCompact 3-vessel gravity flow system with combined mash/lauter tun. Lower cost, easy to use.
Steam breweryUses steam heating instead of direct fire. Consistent, efficient, eco-friendly.
Electric brewhouseHeated by electricity instead of gas or steam. Precise control, operational flexibility.
Automated systemHighly computerized operation with more hands-off functionality.
Custom fabricationTailored system designed for specific space, capacity or vision requirements.\

20 BBL Brewhouse Brewing Process

The typical brewing process in a 20 BBL brewhouse consists of these basic steps performed in stainless steel vessels:

  1. Milling – The grains are coarsely cracked by a mill to expose starches.
  2. Mashing – The milled grain is mixed with hot water in the mash tun and held for 1-2 hours at 150-160°F to convert starches into fermentable sugars. The result is sweet wort.
  3. Lautering – The grain particles are separated from the sweet wort which contains the sugar. The sweet wort is sent to the brew kettle.
  4. Boiling – The wort is boiled vigorously with hops for 1-2 hours to extract flavors, aromas and bitterness. Coagulated proteins form a removable hot break.
  5. Whirlpooling – The hot wort is circulated to create a whirlpool effect separting the clear wort from the hop debris and precipitated proteins.
  6. Cooling – The protein-free hopped wort passes through a plate heat exchanger bringing it down to yeast pitching temperature, around 45-65°F.
  7. Fermenting – The cooled wort is aerated and pitched with yeast in fermenters. Yeast converts sugars into alcohol and CO2 over 1-3 weeks at 45-68°F.
  8. Maturation – The young beer is conditioned for clarity and flavor in bright beer tanks before packaging.

FAQs

What does 20 BBL mean?

20 BBL stands for 20 barrel brewhouse. A barrel is a standard brewing measure equal to 31 US gallons. So 20 BBL = 620 gallons per batch.

What size brewery uses a 20 BBL system?

A 20 barrel brewhouse is typically used by microbreweries and brewpubs producing 300-30,000 barrels per year. At maximum capacity, it can output around 10,000 barrels annually.

How much beer can you produce with a 20 BBL brewhouse?

Operating 1-5 batches weekly, annual production with a 20 BBL system can range realistically between 1,000-10,000 barrels of beer. Efficiency and production schedule determine exact volumes.

How much does a 20 BBL brewhouse cost?

A new 20 BBL brewhouse system usually costs $180,000 to $500,000 depending on the configuration – with an average price around $300,000. Additional costs apply for shipping, installation, peripherals.

What is the difference between a 10 BBL and 20 BBL brewhouse?

  • Batch volume – 10bbl makes 155 gallons per batch, 20bbl makes 310 gallons per batch
  • Annual production – 10bbl lower; 20bbl can produce up to 10,000bbls
  • Vessel size – 20bbl has larger mash tun, kettle etc.
  • Cost – 20bbl system has higher equipment cost
