Overview of pilot brewing equipment

Pilot brewing equipment refers to scaled-down brewing systems used for recipe development, testing, and quality control. They allow new beers to be produced cost-effectively in limited quantities before full-scale commercial production. This article provides a comprehensive guide to pilot brewing equipment covering types, features, sizing, costs, suppliers, installation and more.

Key features of pilot brewing systems:

• Scaled versions of full-sized brewhouses
• Capacities from 1-20 BBLs per batch
• Flexible designs for different recipes and experiments
• Cost-saving way to develop beers with minimized materials and labor
• Provide vital data to plan commercial production

Pilot equipment plays a crucial role in crafting the perfect pint before going big. Let’s explore pilot systems in-depth.

pilot brewing equipment Guide

Commercial pilot breweries contain modular, compact equipment for key brewing stages:

Mashing – Converts malt starches to fermentable sugars

• Mash tun – Mixes crushed malt (grist) and hot water for enzymatic conversion

Lautering – Separates sweet wort from spent grains

• Lauter tun – Sparges grist and filters wort through grate while rinsing sugars

Boiling – Sterilizes wort, extracts flavors, initiates reactions

• Kettle – Brings wort to a boil, usually with external heating

Fermentation – Yeast converts sugars into alcohol

• Fermenter – Closed, temperature-controlled vessel for primary fermentation

Maturation – Allows flavor development before packaging

• Unitank – Secondary aging tank that also serves as bright beer tank

Packaging – Fills product into kegs, cans, bottles, etc.

• Filler, seamer, labeling equipment – Modified versions of full-scale packaging line

Additional equipment like mills, pumps, heat exchangers, control systems tie the process together.

Types of pilot brewing equipment

Pilot breweries are available in different configurations:

Type	Description
All-in-one brewhouse	Integrated mash tun, lauter tun, kettle in single unit with shared components
Individual vessels	Separate mash tun, lauter tun, kettle modules to customize layout
Manual / No automation	Requires user operation of pumps and valves for transfers etc.
Semi-automated	Automated steps but user oversight for recipe control
Fully automated	Pre-programmed recipes with computer monitoring and control

Table 1: Types of pilot brewing systems by configuration and automation level

All-in-one electric and gas-fired brewhouses up to 3 BBL are popular pilot solutions. Larger systems may use modular vessels and partial/full automation. The level of manual operation vs automation impacts complexity, cost and ease of use.

Pilot systems come in many configurations to suit unique production environments, batch sizes and budgets. Dimensions can adapt to existing floorspace limitations if pre-planned.

pilot brewing equipment Process

The typical pilot brewing process resembles full-scale commercial production, just on a reduced scale:

1. Measure out batches of grain and water according to the recipe
2. Mill grains if not bought pre-crushed; transfer to mash tun
3. Mix mash at desired temperature in tun to convert starches and extract sugars
4. Transfer liquid wort to lauter tun; sparge to rinse sugars from grains
5. Pump sweet wort to kettle and boil with hops for sterilization and flavoring
6. Cool boiled wort rapidly to pitching temperature
7. Aerate wort and transfer to fermenter; add yeast
8. Control fermentation temperature profile during conversion of sugars to alcohol
9. Transfer to aging tank for clarifying, carbonating, final conditioning
10. Package finished beer into kegs, bottles, cans using modified small-scale equipment

The process allows tweaking ingredients, temperatures, timings etc. to perfect recipes on a small scale before full production. Automated systems simplify many of these steps for the brewer.

Frequently Asked Questions

Q: Why buy pilot brewing equipment instead of contracting out test batches?

A: In-house pilot systems provide control over the entire R&D process while protecting IP of innovative recipes. They offer the flexibility to experiment freely based on consumer testing and feedback for refinements. Owning pilot equipment also translates operational experience to commercial production.

Q: What size pilot system is ideal?

A: 1- and 3-BBL systems suit most craft breweries launching a pilot program. They minimize capital costs but still yield useful volumes for evaluations. Larger producers may benefit from 7- to 20-BBL setups that mirror full-scale plants more closely at proportionally higher budgets. Every brewer’s needs are unique – discuss goals with the vendor to right-size the system.

Q: Can we resell our pilot equipment later to offset costs?

A: Contract and startup brewers actually constitute a secondary resale market for pilot systems. As companies expand production, pilot lines often get sold to smaller newcomers. Reputable pilot suppliers can also assist finding buyers for preowned equipment. Proper maintenance and service documentation ensures maximum resale value after its initial use.

Q: Are automated pilot brewing systems difficult for our team to operate and maintain?

A: Reputable suppliers offer operator training plus ongoing remote and on-site troubleshooting services for automated equipment. Maintenance is also simplified with diagnostics data plus reminders for periodic inspections, calibrations and validations as needed. Gradually introduce automation with operators present to ease the transition while benefiting from the improved repeatability and data collection compared to manual processes.

Q: What payback period can we expect on a pilot brewery investment?

A: Payback depends heavily on pilot system utilization for continued R&D and for special limited releases. If leveraged effectively full payback on equipment costs within 2 years is common – sometimes faster when considering expensive large-scale failures it averts. Ongoing costs are just ingredients, labor, maintenance and incremental packaging expenses which are modest at pilot volumes.

Additional FAQs about Pilot Brewing Equipment

• Q: How closely can pilot brewing equipment predict full-scale results?
  A: If geometry, thermal profiles, and oxygen controls are matched, pilot systems can reliably forecast extract yield, color (SRM), bitterness (IBU), and aroma trends. Align whirlpool temperatures, boil-off rate, and fermentation profiles for best fidelity.
• Q: What utilities are required to commission a 3–10 BBL pilot system?
  A: Typical needs include 3‑phase power (208/240/480V per OEM), potable water with backflow preventer, glycol supply/return for FV/BBT jackets, steam or natural gas/electric for the kettle, floor drains, adequate ventilation, and CO2/N2 for purging and packaging.
• Q: Should a pilot cellar use unitanks or separate fermenters and brite tanks?
  A: Unitanks increase flexibility (ferment, carb, and condition in one vessel) and reduce transfers/oxygen pickup. Separate FVs + BBTs can improve throughput and scheduling in busy programs but add an extra transfer and cleaning cycle.
• Q: What data should we log during pilot trials for scale-up?
  A: Record mash pH/temps, lauter differential pressure and run-off rate, boil-off %, whirlpool temp/time, knockout DO, fermentation profile and gravity curve, final DO/CO2, sensory notes, and packaging yields.
• Q: How do we streamline CIP on pilot systems without compromising hygiene?
  A: Validate spray coverage, target line velocity ≥1.5 m/s, run 1.5–2.0% caustic at 60–70°C with conductivity endpoints, periodic acid cycles, and document time/temperature/flow. Use ATP or protein swabs to verify.
