How to tilt a cask without disturbing sediment

Last updated: 29 June 2026

Most publicans tilt a cask without thinking, and lose profit every single time they do it. A tilted cask in your cellar isn’t just about pouring a cloudy pint — it’s about sediment suspension, oxygen contact, and the slow degradation of beer quality that your customers won’t notice until they’ve already complained. The difference between a proper tilt and a careless one is the difference between pulling 72 clean pints from a cask and pulling 68, with four of them half-clear. That’s lost revenue you never see, because you’ll assume the cask just didn’t yield as much as you expected.

Tilting a cask properly requires understanding why sediment settles in the first place, what happens when you disturb it, and the exact sequence of moves that gets you what you need without destroying what’s already balanced. This guide covers the real technique — the one you’ll actually use, day in and day out, in a working cellar.

Why sediment matters in a cask

Sediment in a cask is not dirt — it’s yeast, tannins, and hop particles that settle naturally over time as the beer stabilises. A cask sitting upright in your cellar for 48 hours will have most of this material at the bottom. When you tilt too sharply or too often, you suspend it back into the liquid, and the next 15 to 20 pints you pull will be cloudy, flat, or both.

Why does this matter to your margin? Because those cloudy pints are either returned (lost revenue, wasted cost of goods), or they’re drunk by a customer who won’t come back, or they’re poured down the drain by your staff because they look wrong. Most pub operators never track these losses because they assume cask variance is normal. It isn’t — it’s waste, and it’s preventable.

Sediment also affects beer stability. Once suspended, particles in the liquid continue to degrade the beer’s flavour profile and shelf life. A cask with disturbed sediment will drop quality noticeably after 48 hours. A properly settled cask will hold its condition for 10 days or more.

The number that actually matters is wet GP by line, not a single headline stock figure. Draught hides losses in poor cellar temperature and bad line cleaning waste — and in improper cask handling. When you start tracking individual cask condition and tilt technique, you stop guessing at variance and start seeing exactly where the cost goes. A 1% stock loss on wet sales quietly costs a typical pub £3,000–£5,000 a year, and most of that comes from cellar technique, not shrinkage.

The correct tilt sequence

The technique is not complicated, but it requires discipline — and it only works if you do it the same way every time.

Step 1: Check the cask position before you move it

A cask should be resting on its bilge (the curved bottom side) in a cradle or wedge, with the shive (the top hole where you draw beer) facing slightly upward at an angle of approximately 15 degrees. If your cask is resting flat or at a steep angle already, it’s been settled that way and the sediment has arranged itself accordingly. Don’t fight that — work with it.

Step 2: Plan your tilt in advance

Before you touch the cask, know exactly what you’re reaching for. If you’re tilting to check the cask’s remaining content or to draw a sample, decide that now. Random tilts are what destroy casks. Purposeful tilts, done once and settled again, minimise disturbance.

Step 3: Apply steady, controlled pressure

Place your hand or body weight on the lower edge of the cask (the end nearest the floor) and tilt it very slowly toward you or sideways, whichever direction gives you access. The angle should never exceed 45 degrees. The tilt should take a minimum of 5 to 10 seconds — this is not a quick jerk, it’s a slow rotation.

Step 4: Hold the tilt and wait

Once you’ve reached your working angle, hold it still for at least 30 seconds. This gives the suspended sediment time to begin resettling. You’ll feel the weight shift slightly in the cask as the material moves. This pause is not optional — it’s where the magic happens.

Step 5: Do your work (dip, sample, measure) quickly

Now you can dip the cask, insert your sample glass, or do whatever you came to do. Work as quickly as possible while keeping the cask at that stable angle. The longer you hold the tilt, the more risk of sediment re-suspension from vibration and air movement.

Step 6: Return to rest slowly

Lower the cask back to its resting position with the same controlled, slow motion you used to tilt it. Never drop a cask back into place — that shock will suspend every particle you’ve just allowed to settle.

The entire sequence, from first tilt to final rest, should take 2 to 3 minutes. Not 30 seconds. Not while you’re chatting to a delivery driver. Two to three deliberate, focused minutes.

Common mistakes that destroy beer quality

The most common mistake is the quick tilt. A publican needs to check cask content during a busy service, so they grab the cask edge, yank it up to 60 degrees for 10 seconds, squint at it, and push it back. That entire sequence took 20 seconds and just destroyed the last quarter of that cask’s usable yield. You won’t know it until those cloudy pints start appearing three hours later, when you’re in the middle of service.

The second mistake is the repeated tilt. You tilt to check the level. An hour later, a staff member tilts to draw a sample. By lunchtime, three different people have tilted that cask for three different reasons. By the evening service, the sediment is thoroughly mixed and you’re pouring murky draught for the entire shift.

The third mistake is tilting a cask that hasn’t been rested long enough. A cask arrives on the dray, gets put into the cradle immediately, and a staff member tilts it within the first hour to check the volume. The sediment hasn’t settled from transport yet — you’re suspending material that hasn’t even begun to drop. That cask won’t be in proper condition for 48 to 72 hours, no matter how gently you handle it after that first tilt.

The fourth mistake — and this one is silent, because you’ll never see it — is tilting without understanding that SmartPubTools and proper cellar discipline mean you shouldn’t need to tilt a cask more than once a week. If you’re tilting multiple times in a single shift, you don’t have a tilt problem — you have a stock control problem. You don’t know what’s in your casks, so you’re constantly checking. The fix is not better tilting technique; the fix is a weekly count routine that tells you exactly what’s where, so you only handle a cask when you have a planned reason.

Cask position and temperature control

The tilt technique only works if the cask itself is in the right environment. Temperature is your silent killer here.

A cask stored in a cellar above 14°C will have sediment that stays suspended for longer, because warmer liquid has less density and particles move more slowly. A cask at 11–12°C will have sediment that drops much more quickly and stays settled. The difference between a 13°C cellar and a 10°C cellar is the difference between needing to wait 45 seconds for sediment to resettle and needing to wait 20 seconds.

If your cellar is running warm — say, 15°C or above — your tilting technique won’t save you. You’ll still get cloudy pints because the sediment isn’t settling properly at all. The cask position becomes secondary to temperature control. Get the cellar temperature right first; then worry about tilting.

The position of your cask in the cradle affects how quickly sediment reaches the bottom. A cask that’s resting at a 20-degree angle will settle faster than one resting flat, because gravity is doing more of the work. But a cask resting too steeply will cause sediment to build up unevenly, and you’ll get inconsistent quality throughout the cask’s life. Aim for a 12- to 15-degree angle as your standard resting position — not flat, but not steep.

How to measure cask content without full tilt

The best way to check a cask’s remaining content without disturbing it is to use a cask dip stick — a long, thin measure rod that you insert straight down into the cask at a near-vertical angle. Instead of tilting the cask, you’re measuring from directly above.

A proper dip measures the depth of liquid inside the cask from the top. Once you know the depth, you can calculate the remaining content using a simple chart (every cask manufacturer provides these). The entire operation takes 30 seconds and involves zero tilting.

If you don’t have a dip stick, the next best option is a light tilt (no more than 25 degrees) combined with a visual inspection of the shive area. You’re not trying to see the bottom of the cask — you’re just trying to see enough of the liquid surface to estimate the content. This is less accurate than a dip, but it’s faster and causes minimal disturbance.

Most pubs that move from guesswork to a disciplined measuring routine find that they recover 1–2 GP points within a couple of months, simply because they stop losing beer to poor cellar discipline. At my own pub, I was running stock on a tangle of spreadsheets and still losing track of partial kegs and spirit measures. I built a simple count routine around a dipstick and a set of scales, and the weekly variance went from guesswork to a number I could trust within a fortnight. That’s not magic — it’s just the difference between measuring and assuming.

Tracking cask data accurately

Proper cask handling only matters if you’re actually tracking what the cask is telling you. A record of when the cask arrived, how many pints you’ve drawn, the date of the last full tilt, and the cellar temperature at that time — these become your evidence that you’re running cask quality properly.

The StockTap pub stock app lets you log each cask, record its condition during weekly stocktakes, and track drift over time. Instead of tilting a cask three times a week to wonder what’s left, you dip it once, log the result, and move on. You can see which casks are holding condition and which ones are dropping faster than they should — which tells you something is wrong with your handling, your cellar temperature, or your line cleaning.

Most stock loss in draught is actually measurement error and forgotten wastage. When you start logging cask data weekly against till data, you see exactly where the loss is. Is it happening on specific lines? Specific days? Specific pints? The answer changes how you investigate. If you’re losing 10 pints a week from your best-selling ale, but that loss only appears on Friday and Saturday nights, your problem is not the cask — it’s staff free-pouring, or a blocked line, or a temperature spike during service. You’ll never find that without tracking.
