16.5 Gallon Wort Grant Brewing Equipment
Overview of 16.5 Gallon Wort Grant
A 16.5 gallon wort grant is a key piece of brewing equipment used in commercial and homebrew beer production. It is a stainless steel tank that acts as a buffer between the mash tun and brew kettle, allowing more efficient transfers and better control over wort clarity and quality.
Wort Grant Types
There are a few common designs of 16.5 gallon wort grants:
| Type | Description |
|---|---|
| Bottom drain grant with racking arm | Most common design with outlet at bottom and racking arm to transfer wort to kettle |
| Grant with false bottom | Includes perforated false bottom to act as filter for clearer wort transfers |
| Grant with filtration screen | Filter screen ensures only liquid passes through to kettle, leaving behind grains and debris |
Brewing Process Role
A 16.5 gallon wort grant plays an key role in the brewing process:
- Acts as a buffer tank during mash to kettle transfers
- Allows controlling wort flow rate and clarity before boiling
- Provides temporary storage so brew kettle isn’t overwhelmed
- Lets brewer take gravity readings and make adjustments
- Keeps grains suspended during vorlauf recirculation

FAQs
Q: What size wort grant is ideal for a 7bbl brewhouse?
A: For a 7 barrel system, a 20 gallon wort grant is recommended. This provides sufficient capacity without being oversized.
Q: Can I convert a keg into a wort grant?
A: While possible, it is not advisable as the stainless steel alloys and fittings on a converted keg may not be properly designed for repeated exposure to aggressive brewery cleaners and high temperature cycling.
Q: Should I choose a grant with a false bottom or filtration screen?
A: It depends on your budget and clarity targets – false bottoms provide good clarity for most homebrew setups, while filter screens take it to the next level.
FAQ (16.5 Gallon Wort Grant Brewing Equipment)
1) Does a 16.5 gallon wort grant improve lauter efficiency or just clarity?
Primarily clarity. By decoupling pump suction from the mash tun, the grant stabilizes grain-bed hydraulics, which reduces compaction and channeling, indirectly improving lauter efficiency and consistency.
2) What pump setup pairs best with a 16.5 gallon wort grant?
Use a low-shear, VFD-controlled sanitary pump (e.g., centrifugal with throttling valve on the outlet, never on the inlet). Maintain gentle flow from mash tun to grant by gravity, then control kettle transfer with the pump.
3) How should I size outlets and fittings on a 16.5 gal grant?
1.5″ tri-clamp is standard for home-to-nano scale. Include one bottom drain, one racking arm outlet, a dedicated CIP spray port, and a top vent/anti-vac port to prevent siphon or air lock.
4) What’s the best SOP to minimize oxygen pickup from the grant?
Pre-heat and purge the vessel and lines with CO2, keep the lid closed with an anti-foam vent filter, use short hose runs, avoid splashing, and maintain a steady laminar inflow from the lauter grant to the kettle.
5) False bottom vs. filtration screen for a 16.5 gal grant—how to choose?
False bottoms offer robust flow and are easier to CIP; screens yield brighter wort but can blind with fine grists. If you brew with adjuncts or fine crush, select a false bottom or a dual-stage setup (coarse false bottom + removable screen).
2025 Industry Trends for 16.5 Gallon Wort Grant Brewing Equipment
- Low‑O2 lautering: More brewers purge grants and use sealed lids/vent filters to curb hot-side aeration, preserving malt flavor.
- Sensor-ready grants: Welded ports for temperature, turbidity, and level sensors enable semi-automated vorlauf and kettle transfers.
- Quick-CIP design: Spray-ball ports, sloped bottoms, and polished interiors (RA ≤ 0.6–0.8 μm) shorten cleaning cycles.
- Modular mobility: Caster-mounted, lockable frames with hose management reduce trip hazards and speed changeovers.
- Material upgrades: 304 remains common; premium 316L offerings grow where aggressive caustic/acid and high-temp cycles are routine.

Latest Research Cases
Case Study 1: Low-O2 Lautering with Purged 16.5 Gallon Grant (2025)
Background: A 5 bbl brewery reported dull malt character and higher-than-desired color pickup.
Solution: Implemented CO2 purging of the wort grant and hoses, fitted a HEPA vent on the lid, added a turbidity sight and VFD pump control for steady flow.
Results: Hot-side DO reduced by ~35–45%, SRM held ~0.5–1.0 lower on pale beers, with improved malt aroma retention and clearer kettle runoff during vorlauf.
Case Study 2: Dual-Stage Filtration Grant for Adjunct-Heavy Mashes (2024)
Background: Frequent stuck recirculations with wheat/oat-heavy grists on a 16.5 gal grant.
Solution: Installed a perforated false bottom plus a removable 300–400 μm screen, paired with a differential pressure gauge to signal cleaning.
Results: Vorlauf time dropped ~25%, stuck events nearly eliminated, yielding brighter wort to kettle and more predictable brew day timing.
Expert Opinions
- John Mallett, Brewing Operations Expert and author of “Malt”:
“Treat the grant as a hydraulic buffer. If the pump pulls on the mash, you’ll compact the bed. Let gravity feed the grant and meter flow downstream.” - Mary Pellettieri, QA Consultant, author of “Quality Management for Breweries”:
“Instrument the grant minimally—temperature, level, and a visual turbidity indicator. Those three points reduce variability and oxygen risk substantially.” - Ashton Lewis, Technical Brewing Educator (MBAA; former BYO ‘Mr. Wizard’):
“On small systems, a polished, sloped-bottom grant with a real CIP port saves hours over a year. Cleanability is your ROI.”
