Learn how craft breweries track raw ingredients, fermenting batches, keg pools, CO2 gas, and packaging inventory while controlling waste and managing aging schedules.
You have twelve tanks at various fermentation stages, a walk-in full of hops with different harvest dates, a keg pool scattered across 40 accounts, and no way to tell if you have enough CO2 for next week's canning run.
Welcome to craft brewery inventory management — where raw goods are perishable, work-in-progress is chemically active, and finished goods leave the building in containers you don't get back for weeks.
Most small breweries run this on a whiteboard and a prayer. But as you scale past 500 barrels a year, that approach starts costing real money.
Here's how to build an inventory system that keeps your fermenters full and your tap lines flowing.
A brewery doesn't have one inventory — it has four interconnected ones, each with its own tracking rules and failure modes.
Malt, hops, yeast, and adjuncts (fruit, coffee, spices) make up the raw material layer. Unlike retail inventory, these aren't static:
The practical system: Label every ingredient pallet or bucket with receipt date, harvest/vintage, and supplier lot number. Use FIFO strictly — the oldest hops go into bittering additions first, the freshest into dry-hop.
This is the inventory most breweries lose track of. From mash-in to packaging, beer is chemically transforming. You can't "count" a fermenter the same way you count bottles on a shelf.
What to track for each tank:
The common failure: A brewer transfers a batch to a conditioning tank but forgets to update the tracking sheet. Now you have 15 barrels "missing" — not lost, just misattributed. With a proper tank-status board (physical or digital), this never happens.
This is where the money lives — and where it goes missing most often.
Keg tracking is uniquely hard. A keg is both a product container and an asset. When you sell beer to a bar, the keg leaves your inventory as a product... but it must come back as an asset. Most breweries lose 5-15% of their keg pool annually to:
Solution: Assign every keg a serial number (engraved, sticker, or RFID). Track it as a separate asset class with deposit value. Run a monthly keg reconciliation with your top 10 accounts — email each one asking them to count your kegs on hand.
Shelf-stable packaging (cans, bottles, four-packs carriers): Track these as standard inventory with reorder points. Most breweries keep 2-4 weeks of packaging on hand. The tricky part is seasonal label changes — a summer IPA label that's printed but never used is 100% waste.
CO2 is the silent inventory you always run out of on a Friday afternoon.
The trick: Add CO2 to your delivery check-in process. When a fresh tank arrives, note the date. When the regulator drops below 500 PSI, order the next one. A simple email reminder to your gas supplier every 3 weeks prevents most shortage disasters.
If a customer gets a hazy IPA that tastes like buttered popcorn (diacetyl), you need to trace that batch to every keg and can that left the building.
Minimum traceability system:
With this in place, you can trace from "customer complaint on 4/15" back to "Keg #884 filled from BBT-3 on 4/10 using Batch B-2026-IPA-042, dry-hopped with Lot H-2026-Citra-019."
Doing this in a spreadsheet works for small operations. Once you're filling 50+ kegs per week, you'll want a system that tracks batch-to-keg links automatically.
Craft brewery inventory isn't just about tracking what's on hand — it's about planning months ahead.
Typical brewery planning cycle:
| Horizon | What you plan | Risk if wrong |
|---|---|---|
| 3-6 months out | Seasonal recipe design, hop contract commitments | Stuck with 200 lbs of a hop variety nobody wants anymore |
| 4-8 weeks ahead | Production schedule, malt/hop orders | Not having key ingredients for planned releases |
| 1-2 weeks ahead | Packaging material orders (cans, labels, carriers) | Can't run the canning line because labels aren't printed |
| Daily/Weekly | Keg inventory, CO2 levels, cleaning chemical stock | Running out mid-production |
The pro move: Plan your seasonal releases 6 months out. Contract your base hops (Citra, Mosaic, Centennial) annually — you'll save 15-25% vs spot market. Leave 20% of your hop budget for experimental lots and short-notice releases.
Fluxventory was built for businesses with messy, multi-location inventory — which describes every brewery. Our system tracks raw ingredients by lot number and harvest date, fermentation tanks as work-in-progress locations, and kegs as trackable assets with deposit values.
The mobile-first interface means brewers can log transfers and counts from the brewhouse floor without touching a desktop. And our multi-UOM support handles the weird measurements breweries work with — pounds of hops, gallons of wort, cases of cans, and individual kegs as returnable assets.
Try Fluxventory free — no hardware required, works on any phone or tablet.
Stop guessing what's in your tanks and start tracking everything from raw hops to returned kegs. Start your free trial or see our pricing.
