How to Reduce Pub Stock Wastage in 2026

Last updated: 2 May 2026

Most pub licensees have no idea how much stock they actually lose each week. You might think it’s 2–3%, but in my experience across tied and free houses, the real figure is often double that — and nobody’s measuring it. Stock wastage is the silent profit killer that doesn’t show up clearly on your till. A pint gets spilled, a cask sits too long, someone forgets to rotate bottles, a crate goes missing — and suddenly you’re down £50 to £150 a week that you never see leave. Over a year, that’s £2,600 to £7,800 you’re not making. If you’re running a community pub with quiz nights, sports events, and food service all happening simultaneously — like we do at Teal Farm — the complexity multiplies. This article shows you exactly where wastage happens, how to measure it properly, and the specific systems that actually work. You’ll also learn the one thing most pubs get wrong about stock rotation, and why your current method probably isn’t catching the real losses.

Where Stock Wastage Actually Happens in Pubs

Stock wastage breaks down into three categories: spoilage, spillage, and shrinkage. Most licensees focus only on the visible stuff — the spilled pint or broken glass — and completely miss the slow bleed of spoilage happening in the cellar.

Spoilage: The Cellar Problem Nobody Talks About

This is where most of your wastage actually lives. A cask that’s been on tap for three weeks starts to degrade. A bottle with a cork that dries out because humidity is wrong. Draught beer that’s been exposed to sunlight through a window. Spirits that separate or discolour if stored next to a radiator. Temperature fluctuations in a cellar — even small ones — can turn a £50 cask into unservable stock in days.

I failed an NSF audit once before I got the cellar temperature control right. The auditor found bottles that should have been pulled weeks earlier. I wasn’t being careless; I simply didn’t have a proper logging system. Now we log cellar temperatures six days a week, and I spot problems before they become wastage. That single change probably saved me £200–£300 a month in spoilage alone.

Spillage and Breakage

This is the visible bit. A pint spilled during service. Glassware broken. A keg dropped. A cask valve malfunctions and leaks. These are easier to spot than spoilage, but they’re also harder to prevent unless you have systems in place. At Teal Farm, we run quiz nights and match days, which means high-pressure service and more opportunities for spillage. Training staff to understand the cost of spillage — and giving them clear procedures for measuring and recording it — reduces it significantly.

Shrinkage: The Unmeasured Leak

This is the uncomfortable bit. Unrecorded pours. Staff having a taste to check the product. Free pints given to regulars or mates. Bottles that go missing. Till discrepancies that never get investigated. Most pubs don’t want to look too hard at shrinkage because it often points to staff dishonesty, which is awkward to manage. But without measuring it, you can’t fix it. The key is creating an environment where measurement is routine and non-accusatory — more about accuracy than blame.

How to Measure Your Real Wastage Rate

The most effective way to measure pub stock wastage is through weekly stock counts paired with till reconciliation and cellar temperature logs, not through one-off annual stocktakes. Annual stocktakes hide the real pattern. They tell you where you end up, but not where you leak.

The Weekly Count Method

This is labour-intensive but essential. Every Monday morning (or whatever day works for your pub), count your opening stock. Every Friday, count your closing stock. Use the same person if you can — consistency matters. Record the count in a spreadsheet or system. Then, calculate:

• Opening stock + purchases that week − closing stock = stock used
• Stock used should match till records (within 2–3%)
• Anything beyond 3% is potential wastage or theft

This sounds simple but it reveals everything. I did this for a month when I first took over Teal Farm under my Marston’s CRP agreement, and I found we were losing about 5% more stock than till records showed. Once I started the weekly count, staff knew they were being watched, behaviour changed, and within six weeks we’d brought it down to 2%. That’s nearly £200 a month back in margin.

Use a stock take template to keep your counts consistent. The template forces you to categorise by product type (cask, keg, bottle, spirit, mixer) and flag anything unusual.

Till Reconciliation

Your EPOS system should tell you exactly how many pints, bottles, or measures you sold that week. If your physical count doesn’t match till records, something is wrong. The discrepancy might be honest — a till error, a complimentary drink that wasn’t logged, a customer complaint where you gave a free pint. But you need to know. Most pubs using our best pub EPOS systems guide can pull this data in minutes.

The key is doing this weekly, not at year-end when you can’t remember what happened.

Cellar Temperature and Condition Logs

Record cellar temperature at the same time each day. Most spoilage happens because temperature drifts. If your cellar runs at 18°C one day and 12°C the next, cask integrity suffers. Draught lines need to stay between 10–14°C. Spirits should be stored at stable room temperature, not in a hot cellar or next to a boiler.

You don’t need expensive monitoring equipment. A simple digital thermometer (£5 from any hardware store) and a log sheet works. Write it down. If the cellar temperature is outside range, you’ll have a record of when spoilage was likely and can investigate.

FIFO Stock Rotation: Why It Fails Most Pubs

FIFO — First In, First Out — is the standard pub stock rotation method. It’s simple: oldest stock moves to the front, newest stock to the back. In theory, nothing sits on a shelf long enough to go off. In practice, it fails because pubs treat it like a nice idea rather than a daily enforcement system.

FIFO only works if someone checks every bottle and cask every single day, and your cellar layout physically supports moving stock forward. Most pubs don’t have the cellar space to do this properly. A typical tied pub cellar in the UK is cramped, with kegs stacked three-high and bottles wedged into shelves. You can’t rotate properly. So FIFO becomes theatre — everyone nods along, but nobody actually does it.

What Actually Works: Date-Based Culling

Instead of FIFO, I use a date-sticker system. Every bottle and cask gets dated the day it arrives (or the day it’s opened, for draught). Every Friday, I walk through the cellar with a list of what should be pulled. If a cask was opened more than 21 days ago, it comes off. If a bottle is beyond its best-before date, it goes. No exceptions. No judgment.

This is mechanical. It doesn’t rely on staff memory. It doesn’t depend on cellar layout. And it’s cheap — date stickers cost pennies. When you pull stock early, it feels wasteful, but you’re actually preventing the spoilage that costs more.

The Real Cost of FIFO Laziness

A customer complains that a pint of bitter tastes off. You’re out the cost of that pint plus a replacement. But the real cost is the cask sitting in your cellar degrading, probably serving another five or six off-tasting pints before it gets pulled. That’s £20–£30 in lost goodwill and stock. A date-based system catches this before it becomes a problem.

Cellar Management and Temperature Control

The cellar is where most wastage begins. If your cellar environment isn’t right, everything else you do becomes harder. Temperature, humidity, light, and cleanliness all matter.

Temperature: Non-Negotiable

Cask and draught beer needs 10–14°C. Most UK pub cellars run closer to 12–13°C, which is fine. But if you have a cellar next to a boiler, or a bar where afternoon sun heats the walls, or a cellar door that’s left open during summer, temperature swings up to 18°C or higher. That kills product. Spirits should sit at 15–18°C, stable. Get a decent thermometer, log it daily, and if temperature is drifting, fix it. Insulation, a vent, or air conditioning — depending on the problem.

Humidity and Ventilation

A damp cellar breeds mould and damages labels. A dry cellar dries out cork seals. Aim for 60–70% humidity. If your cellar is in a basement below ground level, you may have moisture problems. Proper ventilation helps. A cracked cellar window is better than sealed air.

Light and Cleanliness

Keep the cellar dark. Sunlight damages beer. Clean the cellar floor regularly — standing water attracts pests and creates smells that can taint product. A clean cellar also makes stock rotation visible. You can actually see what’s where.

All of this sounds basic, but I failed my first EHO inspection on cellar cleanliness alone. The inspector noted mould on shelving and general clutter. I got a pass on the re-inspection, but it cost me time and money. Now we have a cellar cleaning checklist and someone responsible every week. It’s also part of your pub fire risk assessment — blocked access to a cellar is a fire safety issue.

Staff Training That Actually Sticks

This is where most pubs fail. You tell staff once not to waste stock, and then you expect them to remember. They don’t. Training has to be repeated, specific, and tied to something staff care about — usually money or avoiding trouble.

Make Wastage Visible and Personal

Show your staff what wastage actually costs. A spilled pint costs £3–£4 in product. A broken glass is another £0.50. Forty spilled pints a month is £120–£160 in lost margin. If staff know a high wastage week means reduced hours or no staff party fund that month, behaviour changes. This isn’t punishment — it’s accountability.

Create a Wastage Procedure

Every spill, every breakage, every early pull gets recorded on a simple log. Not to blame anyone, but to spot patterns. If one person is spilling pints regularly, that’s a training issue. If breakage happens mostly during quiz night, you need more glasses and better space management. If early pulls are high, there’s a cellar problem.

I track wastage by category and review it in our monthly staff meeting. It’s not accusatory — it’s “Here’s where we’re losing money this month. How do we fix it?” Staff actually engage with this, especially if they see the number improving.

Tie Training to Pub Command Centre

When staff understand that Pub Command Centre is tracking their stock usage and comparing it to till records in real time, they take more care. It’s not Big Brother — it’s accuracy. At Teal Farm, we use the cellar management screen to flag which kegs have been open longest, which casks are near their pull date, and which product types are drifting away from till records. Staff know the system is watching for waste, not watching them. The distinction matters.

Systems That Catch Wastage Before It Costs You

An integrated system that tracks cellar stock, temperatures, till records, and staff activity in one place catches 70–80% more wastage than a spreadsheet or manual system. This isn’t marketing speak. I’ve done both. Spreadsheets work until they don’t — someone forgets a column, a formula breaks, or you realise three weeks later that you lost the data.

The Right EPOS System Matters

A good EPOS system should tell you exactly what you sold. But most EPOS systems stop there. They don’t connect to your cellar. They don’t show you temperature data. They don’t flag when a cask has been open too long. Review our best pub EPOS systems guide — look specifically for systems with cellar integration, not just till records.

At Teal Farm, we found that EPOS alone wasn’t enough. We needed something that also tracked our cellar. That’s when we moved to a system that logs everything in one place.

Cellar Tracking Software

This is the missing piece for most pubs. You need to log:

• Date received for every cask and bottle
• Date opened for draught products
• Cellar temperature, daily
• Date pulled, and reason (consumed, spoiled, overstocked)
• Any spillage, breakage, or unusual issues

This sounds like a lot of data entry, but if the system is designed for pubs, it should take 10 minutes a day. If it takes longer, it won’t stick.

Weekly P&L Visibility

Once you have cellar data and till data, you need to see the picture together. Your pub profit margin calculator should show you:

• Gross profit by category (wet, dry, food)
• Actual vs expected stock usage
• Wastage as a percentage
• Variance from last week and year-to-date

When you see that your GP on cask is 68% but it should be 72%, you know there’s a problem. You can then drill into cellar logs and till records to find it. This level of visibility is transformative. It’s the difference between running a pub on gut feel and running it on numbers.

At Teal Farm, our best revenue year was 2025, partly because we got serious about wastage measurement and fix in 2024. Labour cost averaging 15% against the UK benchmark of 25–30% doesn’t just come from cheap staffing — it comes from systems that work. One of those systems is knowing exactly where our stock goes.

The Math: What Wastage Actually Costs You

Let’s say your pub turns over £4,000 a week in stock. A 5% wastage rate is £200. Over a year, that’s £10,400. A lot of pubs think they’re at 2–3%, but if they actually measured properly, they’d find 5–8%. The difference between 3% and 8% is £2,600 a year. That’s real money.

When I first took on Teal Farm three years ago on my birthday, I did a full ingoing audit. The previous licensee had never measured wastage properly. There were casks in the cellar that had been open for months. The temperature varied wildly. I found probably £500 in spoilage that should have been pulled weeks earlier. The new owner wasn’t stealing — they just didn’t have systems.

If you’re currently running without proper measurement, you’re almost certainly losing more than you think. The first step is measuring. The second step is fixing. The third step is staying fixed with routine discipline.
