Track Cask Ale Margins Like a Pro in 2026

Last updated: 10 April 2026

Most pub landlords have no idea what their cask ales actually cost them to pour. You buy a £90 cask, pour it over a week, and hope you’ve made money. That’s not management — that’s gambling.

I spent five years watching cask margins slip away because I couldn’t see the numbers clearly. Waste, over-pouring, spoilage, wrong pricing — it all added up. Then I started tracking every single cask properly, and within two months I’d identified £200+ in unnecessary losses each week.

A cask ale margin tracker is the difference between running your cask programme like a business and just hoping it works out. This guide shows you exactly how to track margins, what numbers to watch, and the systems that actually work — based on real data from working pubs.

What Is a Cask Ale Margin Tracker?

A cask ale margin tracker is a system that records the true profitability of every cask you buy and sell. It captures four core data points: what you paid for the cask, how many pints you actually poured, how much you sold it for, and how much was wasted or given away.

Most pubs track only the purchase invoice and the till revenue — they miss everything in between. That’s where margins disappear.

The tracker works by giving you a single view of each cask from delivery to disposal. You know the cost, you know the revenue, and you can see exactly what percentage became profit. Over time, you spot patterns: which brands pour clean, which ones waste, which styles sell faster, and which are dead weight on your bar.

At The Teal Farm, I used to run a simple tracker on paper — just four columns and a spreadsheet. Took 20 minutes a week. Within a month I could see which casks made £120 profit and which made £40. I stopped ordering the slow ones entirely and added a second line of the fast ones. Margins jumped 8%.

Why Cask Margin Tracking Matters for Pub Profits

Cask ale is one of the last remaining high-margin products in hospitality. A pint that costs you £1.20 to pour can sell for £5.50. That’s 78% gross profit — if you don’t waste it.

But most pubs don’t see that profit because they don’t measure it. Here’s what actually happens:

• A cask sits on the bar too long and goes flat before half-selling — waste, loss
• Bar staff pour inconsistent measures without realising it — you lose 2–3 pints per cask
• You price a cask the same as last month without checking if the input cost changed — margin shrinks
• A brand doesn’t sell and you discount it to clear — you just taught customers your pricing is negotiable
• You can’t see which cask is costing you until it’s already in your cellar

Without a tracker, these losses are invisible. With one, you fix them in real time.

Tracking cask margins gives you three immediate wins: you stop losing money to waste, you price accurately instead of guessing, and you stock only what actually sells.

Most pub owners find £50–150 in hidden monthly savings in their first week of proper tracking. One landlord in Manchester implemented a simple Pub Command Centre margin tracker and caught that three casks were being consistently over-poured by 4 pints each per week. That was £180 a month he didn’t know he was losing.

The Problem With Manual Spreadsheets

I get it — spreadsheets feel free and flexible. You can track anything. In reality, manual cask tracking fails because it’s too easy to skip.

Here’s what happens in practice:

Monday comes, you’re busy, you don’t write down the cask details. Tuesday you try to remember — was it the 4.2% or 4.5%? By Friday you’ve guessed half the data. By the following week, you’ve abandoned the whole thing.

Even when pubs stick with spreadsheets, they’re missing data they should have. They record the cost and revenue, but not the pints poured or the wastage. They can’t calculate the real margin because they’re working with incomplete numbers.

Manual tracking also creates input errors. Someone writes down “23 pints sold” when it was 32. Someone records the cost wrong. The spreadsheet doesn’t catch these mistakes — they just propagate into your next month’s decisions.

The real problem: spreadsheets take 8–12 hours per month to maintain, and they still don’t give you insight. You’re busy with paperwork instead of running your pub.

More importantly, spreadsheets don’t tell you anything automatically. You finish entering data and then — what? You still have to manually compare prices, spot trends, and figure out which casks are underperforming. A working system should do that for you.

How to Calculate Real Cask Ale Margins

Before you build a tracking system, you need to understand the calculation. Get this right and everything else is just data entry.

The formula is simple, but most pubs skip the most important steps:

Cask Margin % = (Revenue – Cost – Waste) ÷ Revenue × 100

Breaking this down with a real example:

• Cost: You buy a 9-gallon cask for £90
• Usable pints: A 9-gallon cask yields approximately 53 pints when poured correctly (accounting for head space and tap spillage)
• Actual pints sold: You pour 48 pints and sell them all at £5.50 each = £264 revenue
• Waste: 5 pints went flat, were over-poured, or given away. At £5.50 per pint, that’s £27.50 in lost revenue
• Real revenue: £264 (what actually made it to the till)
• Margin: (£264 – £90) ÷ £264 = 66% gross profit per cask

Now — if you don’t track the waste line, you think your margin is (£264 – £90) ÷ £264 = 66%. But your true margin is lower because you lost 5 pints of sellable product. That’s the invisible loss most pubs miss.

The most effective way to track cask margins is to capture four data points at every pour: cask name and brand, purchase price, number of pints actually poured, and number of pints sold. From these, everything else calculates automatically.

Here’s what you need to record for each cask:

• Brand and style: Which cask is this? (Timothy Taylor Landlord, Wainwright, etc.)
• Purchase price: What did you pay? (£88, £92, whatever your invoice says)
• Date on tap: When did you crack it open?
• Pints poured: How many pints did this cask yield? (Track this by keeping a tally or reading your dispense system)
• Pints sold: How many actually made it to customer glasses? (This is till revenue ÷ pint price, rounded)
• Price per pint: What did you charge customers?
• Date emptied: When was the cask done?

Once you have these numbers, your margin tracker calculates the rest: gross revenue, wastage cost, net profit, and margin percentage.

Building a Real Tracking System

You don’t need software to track cask margins — but you need a system that works faster than manual entry and catches mistakes.

Here’s what I recommend, based on what actually works in real pubs:

Step 1: Capture Data at Point of Use

Don’t try to remember cask details from memory. Record them when you tap the cask and when you empty it. Use a clipboard on the bar, a Google Sheet on your phone, or a proper system. Pick something you’ll actually use.

At The Teal Farm, I kept a simple printed sheet next to each tap. Staff wrote down the cask name, tap date, and a daily tally of pints poured. Took 30 seconds per day. When the cask was empty, I photographed the sheet and filed it.

Step 2: Record Your Costs Right

Use the invoice price, not what you remember paying. Costs change monthly. If you’re ordering from the same distributor but paying different prices, your margins are actually changing — you need to know that.

Set up a simple cost log where you paste invoice details as you receive deliveries. Brand, size, cost. That’s all. Takes two minutes per delivery.

Step 3: Measure Pours Accurately

This is where most pubs fail. You can’t guess how many pints a cask yielded. You have to count.

Best practice: use a pour counter (a tally app or manual clicker next to each tap), or use your till system if it tracks by pump. Some modern dispensers have electronic counters built in — use them.

If you’re pouring manually, designate one person per shift to tally pints on the cask record sheet. It takes 3 seconds per pour.

Without pour counting, you don’t know if staff are over-pouring, whether the cask is yielding normal pints, or where wastage is happening. You’re flying blind.

Step 4: Calculate Weekly, Not Monthly

Don’t wait until month-end to look at your numbers. Calculate margin on each cask as soon as it’s empty — while the data is fresh and you can still act on it.

Spending 15 minutes every Sunday reviewing the week’s cask margins takes you from reactive to proactive. You spot problems immediately and adjust ordering before they compound.

Step 5: Use a System That Connects to Your Till

SmartPubTools users with Pub Command Centre can connect their till data directly, which means pint sales are calculated automatically — no manual entry, no guessing. The system knows exactly what revenue came from each product line.

If you’re using a modern till system that tracks sales by product, export that data weekly and match it to your cask records. Modern dispensers often have this built in already — you’re just not using it.

Common Cask Tracking Mistakes (And How to Avoid Them)

I’ve made all of these. So have most pub landlords. Here’s what to avoid:

Mistake 1: Not Accounting for Waste

You record 48 pints sold and assume that’s the margin. But 5 pints went flat, were over-poured, or were given away. Your real margin is 8% lower than you think.

Fix: Track pints poured vs. pints sold separately. The difference is your waste percentage. Monitor it weekly. If waste creeps above 10%, something is wrong — staff training, equipment issue, or the cask is just a bad batch.

Mistake 2: Inconsistent Pricing

You charge £5.50 for Landlord one week and £5.20 the next because you forgot to update. Your margin tracking becomes meaningless because the price in your system doesn’t match reality.

Fix: Set a pricing rule for each cask at the start of the month. Write it down. Train staff. If you change price mid-month, update your tracking immediately. Use your till system to enforce pricing — don’t rely on staff memory.

Mistake 3: Mixing Cask Sizes Without Tracking Them

You order both 9-gallon and 4.5-gallon casks, but your tracker just says “Landlord” without specifying size. A 9-gallon cask yields 53 pints; a 4.5-gallon yields 26. Your calculations are now wrong by 50%.

Fix: Always record cask size. Let the system calculate theoretical yield. Then record actual pints poured and measure the difference. Small casks waste percentage looks different from big casks — you need to see that.

Mistake 4: Not Tracking Empty Casks

You empty a cask and don’t record it. A month later, you have invoices for casks you never matched to sales data. Your margins are incomplete.

Fix: Every cask that comes in must have an “empty” record before you buy the next one. If an invoice doesn’t match a cask record, something went wrong — either wrong cask delivered, or you forgot to track it. Fix it immediately.

Mistake 5: Ignoring Seasonal Changes

A cask margin that works in summer might be terrible in winter. Dark ales sell faster in November than August. Light ales the opposite. But many pubs keep ordering the same mix year-round.

Fix: Review your best-selling casks by season every three months. Track which ones perform and which ones die seasonally. Adjust your standing orders accordingly. You should have different cask lists for autumn, winter, spring, and summer.

Mistake 6: Not Separating Margin From Volume

A cask might have a 60% margin but only sell 30 pints. Another has a 55% margin but consistently sells 50 pints. The second one makes you more total profit — but if you only track percentage margin, you’ll keep ordering the first.

Fix: Track three numbers: margin %, pints sold, and total profit per cask. Rank by total profit, not percentage. A 50% margin on 50 pints (£125 profit) beats a 65% margin on 25 pints (£72 profit).

Frequently Asked Questions

The Real Impact of Proper Cask Tracking

I’m going to be direct: most pubs leave £1,500–3,000 per year on the table because they don’t track cask margins properly. That’s not guessing — that’s based on watching pub after pub find exactly these numbers once they implement a real system.

The wins come from three places:

• Waste reduction: Once you see the number, you fix it. 3–5% reduction in waste is normal in the first month. That’s £300–500 annually on a typical cask range.
• Right-sizing your range: You stop ordering slow casks and focus on fast ones. Faster turnover means fresher product, fewer tanks going off, and more profit. This alone generates £500–1,000 annually.
• Smarter pricing: You price based on cost and demand data, not guesses. You find the casks where you’re under-charging and adjust. Additional £200–800 annually.

At The Teal Farm, I implemented proper tracking over a weekend using a simple spreadsheet and a tally sheet next to each tap. Within three months, my cask programme profit increased by 12%. That’s genuine money.

The barrier to entry is low. You don’t need expensive software. You need a system you’ll actually use and the discipline to record data when you tap and empty casks. That’s it.
